Twenty years in the past, Professor Charles Xavier and Erik Lehnsherr meet young Jean Grey at her parents' house to invite her to join their school, the X-Mansion. Ten years later, the industrialist father of Warren Worthington III discovers his son is a mutant as Warren tries to cut off his wings.
In the present, Worthington Labs announces it has developed an inoculation to suppress the X-gene that gives mutants their abilities, and offer the "cure" to any mutant who wants it. The cure is created from the genome of a young mutant named Jimmy, who lives at the Worthington facility on Alcatraz Island. While some mutants are interested in the cure, including the X-Men's Rogue, many others are horrified by the announcement. Lehnsherr re-establishes his Brotherhood of Mutants with those who oppose the cure, warning his followers that the cure will be forcefully used to exterminate the mutant race.
With help from Pyro, Lehnsherr recruits Callisto and several other mutants. They attack the mobile prison holding Mystique to free her, also freeing Juggernaut and Multiple Man. Mystique saves Lehnsherr by taking a shot of the mutant cure aimed at him, rendering Raven Darkhölme human. Hateful of humans, Lehnsherr abandons Darkhölme, much to her shock and disappointment. Meanwhile, Scott Summers, still distraught over the loss of his fiancée, Jean Grey, drives to her resting location at Alkali Lake. Jean appears to Summers but, as the two kiss, Jean kills him. Sensing trouble, Xavier sends Logan and Storm to investigate. When they arrive, they find only telekinetically floating rocks, Summers' glasses, and an unconscious Jean.
When they return to the X-Mansion, Xavier explains to Logan that when Jean sacrificed herself, she also freed the "Phoenix", a dark and powerful alternate personality which Xavier had telepathically repressed, fearing the Phoenix's destructive potential. Logan is disgusted to learn of this psychic tampering with Jean's mind but, once she awakens, he discovers that she killed Summers and is not the Jean Grey he once knew. The Phoenix emerges, knocks out Logan, and escapes to her childhood home.
Lehnsherr learns of Jean's resurrection through Callisto, and the X-Men arrive at the Grey home at the same time as the Brotherhood. Lehnsherr and Xavier go in alone, and both vie for Jean's loyalty until the Phoenix resurfaces. She destroys the house and disintegrates Xavier before leaving with Lehnsherr. The Brotherhood decides to strike Worthington Labs, and the government sends multiple teams to attack the Brotherhood's base in the forest, with information gained from Darkhölme, furious over Lehnsherr's betrayal. However, the life forms in the camp are all copies of Multiple Man, and Lehnsherr uses his powers to move the Golden Gate Bridge so he and his army can get to Alcatraz and facilitate the attack on Worthington Labs. The remaining X-Men confront the Brotherhood, despite being significantly outnumbered, and arrive just as the military troops who thus far have been neutralizing the attacking mutants are overwhelmed by the Brotherhood.
During the fight, Kitty Pryde saves Jimmy from Juggernaut, who had been sent to kill him. Logan has Colossus throw him at Lehnsherr and distract him long enough for Hank McCoy to inject Lehnsherr with the "cure" and thus nullify his powers. Army reinforcements arrive and shoot at Jean just as Logan had calmed her down. The Phoenix is awakened by the attack and disintegrates the troops in retaliation. The Phoenix then begins to destroy Alcatraz and anyone within range of her powers. Logan realizes that only he can stop the Phoenix due to his healing factor. When Logan approaches her, Jean momentarily gains control and begs him to save her. Logan fatally stabs Jean, destroying the Phoenix, but mourns for her death.
Sometime later, mutant rights are finally obtained and Xavier's school is still operating with Storm as headmistress. The President of the United States appoints McCoy as ambassador to the United Nations. Rogue reveals to Bobby Drake that she has taken the cure, much to his disappointment. Meanwhile, Lehnsherr sits alone at a chessboard in a San Francisco park. As he gestures toward a metal chess piece, it wobbles slightly, indicating his powers to be returning and the "cure" to be temporary.
In a post-credits scene, Moira MacTaggert checks on a comatose patient who greets her with Xavier's voice, leaving her startled.Hugh Jackman as Logan / Wolverine
A Canadian mutant born with hyper-acute, animal-like senses, claws on his hands, and an accelerated healing factor that made it possible to implant a coating of the indestructible metal alloy adamantium on his skeleton. Jackman was pleased to see that the script allowed Wolverine to expand his character choices, as instead of questioning whether he would remain a loner or join the X-Men, Logan now is asked if he will play a leadership role in the X-Men.
Halle Berry as Ororo Munroe / Storm
A mutant, who is one of Xavier's earlier students and the leader of the X-Men in Cyclops' absence. Storm is a woman with the ability to manipulate the weather. Berry had stated during interviews for X2
that she would not return unless the character had a significant presence comparable to the comic book version, leading to a larger role in The Last Stand'
s script. Berry declared that her ethnicity made the actress identify with the cure plot: "When I was a child, I felt that if only I could change myself, my life would be better. As I've gotten older, I've come to terms with what utter nonsense that is." The character was given a more modern haircut, and costume designer Judianna Makovsky opted to give Storm more black clothes, a color she only wore in the leather costume for previous films, to make her "tougher and sexier".
Ian McKellen as Erik Lehnsherr / Magneto
Leader and founder of the Brotherhood, Magneto is a mutant Holocaust survivor who wages war against humanity in the name of mutant superiority. He has the ability to control and manipulate metal, making him one of the most powerful mutants. Well-known for his homosexuality, McKellen found a parallel of the cure with many prejudices: "It's abhorrent to me, as it would be if a person said I need curing of my sexuality, or if someone said that black people could take a pill that would 'cure' them of being black." McKellen's shooting schedule had to accommodate his work in both The Da Vinci Code
and the London theatre, going as far as filming the actor in England to later superimpose into the Vancouver plates.
Famke Janssen as Jean Grey / Phoenix
A mutant former member of the X-Men, a Class 5 mutant who possesses potentially limitless telepathic and telekinetic powers. The X-Men learn that she has survived the flooding dam from the previous film, but when the rest of the team finds her, Grey has given in completely to her aggressive alternate personality of her powers, the Phoenix. Her mutant powers rival those of Xavier. The writers described the multiple personalities was "an Oedipal drama played out", where the Phoenix was "someone embodying [a] Greek goddess" , while Jean Grey kept the character as "a human, grounded in Freudian terms, a victim, a schizophrenic. To mark the change of Jean Grey into Phoenix, her wardrobe focused on red colors, and everyday fabric in contrast to the leather costumes of the X-Men. Digital make-up also made Jean's face darker with her skin showing some veins and her eyes turning black, signifying the Phoenix personality of her powers.Haley Ramm as Young Jean Grey
Anna Paquin as Marie / Rogue
A young mutant woman whose power causes her to temporarily take on the powers of anyone she touches, leaving her victims (mutant or human) unconscious, Rogue's lack of control over her power causes a great deal of strain on her relationship with Iceman. Paquin declared that while Rogue did not have "a large physical component in this movie", the "adult decisions" the character was forced to do made for more intensity on the emotional side.
Kelsey Grammer as Dr. Hank McCoy / Beast
A mutant former student of Xavier's Institute for Gifted Mutants who is now a member of the U.S. Cabinet as the Secretary of Mutant Affairs, Beast is a brilliant scientist and statesman. He is covered in blue fur and has heightened strength, reflexes and agility, as well as pointed fangs and a lion-like roar. Grammer's make-up took three hours to apply, it involved applying latex prosthetics before painting his eye area and lips blue, applying various hair pieces and wigs, and a muscle suit covered with a hand-punched fur suit.
James Marsden as Scott Summers / Cyclops
A mutant, who is X-Men's field leader, Cyclops emits powerful energy blasts from his eyes, and must wear specially made glasses to prevent the destruction of anything he looks at. Although he is in a committed relationship with Jean Grey, her Phoenix persona kills him early in the film. Marsden saw no problem in having a smaller role, as the films opted to feature Wolverine as the standpoint character, and feeling that "it's difficult when you have however many new characters that you're trying to introduce to an audience in 90 to 120 minutes, to give everyone their due."
Rebecca Romijn as Raven Darkholme / Mystique
Magneto's mutant blue-skinned right-hand woman possesses the ability to shape-shift to mimic anyone's appearance, as well as fight with incredible agility, reflexes and strength. She jumps in front of cure darts intended for Magneto and, after she loses her mutant abilities as a result, Magneto abandons her. Romijn described this story as "a traumatic experience" for Mystique, given that the previous movies implied that she and Magneto had "a deep-seated bond", and becoming "a frail mortal would be her worst nightmare".
Shawn Ashmore as Bobby Drake / Iceman
A young mutant, Iceman can create constructs of ice or blasts of cold. Ashmore's commitments to X-Men
made him decline Bryan Singer's invitation to play Jimmy Olsen in Superman Returns
. The actor was content with his bigger role after Bobby joined the X-Men main team in X2
, as during the predecessor's production he wondered "When do I get to freeze something or get into a fight?"
Aaron Stanford as John Allerdyce / Pyro
A mutant who was a former student of Xavier's School for Gifted Mutants with a grudge against his former friend Bobby Drake, Pyro has the ability to manipulate fire, generated through wrist-mounted lighters. Stanford stated that with the Brotherhood, Pyro "is allowed to fully explore his power" for lacking moral restraints. The actor was comfortable with returning to the role, particularly for following The Hills Have Eyes
, which had an exhausting shoot in the Moroccan desert, while Pyro was nowhere as physically demanding – "My character's pretty much stand-and-deliver, stand there and throw fire at people. There's no acrobatics."
Vinnie Jones as Cain Marko / Juggernaut
A mutant criminal recruited by the Brotherhood in a prison truck, Juggernaut is incredibly strong, fast and, once he gains momentum, he is nearly unstoppable. The film's version of Juggernaut is depicted as a mutant and his relation to Charles Xavier was never mentioned. Matthew Vaughn cast Jones, who he met producing the Guy Ritchie gangster movies where Jones begun his acting career. The actor had to go through a four-hour make-up process to portray Juggernaut, which included a muscle suit and a prostethic chin. The costume tried to retain the bullet-shaped helmet of the comics without going excessively over the top.
Patrick Stewart as Professor Charles Xavier
A mutant with uncharted telepathic powers, and founder of Xavier's Institute for Gifted Mutants. Xavier is an authority on genetic mutation and an advocate of peaceful relations between human and mutant kind. Stewart signed to the film without knowing Xavier would die, and not meeting original director Matthew Vaughn – both would meet in Manchester, where Stewart was filming Eleventh Hour, but eventually Brett Ratner called to introduce himself as the new director.
Ellen Page as Kitty Pryde
A mutant with the ability to phase through matter and walk through solid objects, her clear affection for Iceman further adds to the tension already present between Iceman and Rogue. Maggie Grace was considered for the role, before Ratner invited Page, who impressed the director with her performance in Hard Candy
. The actress initially declined, not wanting to yet jump to Hollywood filmmaking, but accepted after reading the script. Page said part of her motivation was having a new experience: "I thought, well, when else am I going to have a chance to wear a leather suit and run through exploding things? Why not be a superhero for a change?"
Ben Foster as Warren Worthington III / Angel
The mutant son of an industrialist, who has feathered wings which allow him to fly. The static wings were models with a 15 feet (4.6 m) wingspan and 5 feet (1.5 m) height glued to Foster's back, replaced with computer-generated ones when movement was required.Cayden Boyd as Young Warren Worthington III
Dania Ramirez as Callisto
The leader of The Omegas, Callisto is a mutant with enhanced superhumanly acute senses, who senses mutants and their powers, and possesses superhuman speed and reflexes. The character combined the powers of the comics' Callisto with another of the Morlocks, Caliban, and was written as someone who could be "beautiful, but with a tough persona". Ramirez had originally auditioned to play the mutant prostitute Stacy X, and impressed Brett Ratner so much the director decided to bring her to play Callisto.
Michael Murphy as Warren Worthington II
The head of Worthington Labs, the corporation developing the "cure", Worthington expects to rid his son of his mutant abilities. The addition of the character allowed to integrate Angel into the cure plot, which also added a parallel between Warren's discovery of his son's mutation with a father finding out about his son's homosexuality.
Shohreh Aghdashloo as Dr. Kavita Rao
A scientist who works at Worthington Labs on the mutant cure, she is killed by Kid Omega. Aghdashloo signed without a completed script, and erroneously said her character would be mutant doctor Cecilia Reyes.
Josef Sommer as The President
The President of the United States is tolerant of mutants, but fearful of the Brotherhood's threats. While creating the role, the producers felt that a "different" president, like an African American or a woman, had become a cliché in itself and went for a traditional route with an elder caucasian man. Sommer was invited by Ratner following their collaboration in The Family Man
Bill Duke as Trask
The head of the Department of Homeland Security, Secretary Trask aids the president of the United States during the war against the mutants. His first name was never mentioned in the film and is portrayed as African American. In the comics, Bolivar Trask is the head of Trask Industries and creator of the mutant-hunting Sentinels. The comics version of Bolivar Trask is later played by Peter Dinklage in X-Men: Days of Future Past
Daniel Cudmore as Peter Rasputin / Colossus
A mutant with the ability to transform his body into an organic steel, while also granting him superhuman strength and a resistance to physical damage while in that form. Cudmore wore a foam latex muscle suit covered with a chrome-plated plastic plus a hard plastic head to have the metal skin on the set, with some digital augmentation being used to enhance the facial expressions. A digital double was used only for stunts that could not be achieved practically, such as the Fastball Special where Colossus throws Wolverine.
Eric Dane as Multiple Man
A mutant and thief recruited by the Brotherhood in a prison truck, Madrox has the ability to create a very large number of copies of himself. The writers considered Dane's performance memorable despite being featured in only two scenes. Madrox's wardrobe invoked the symbols worn in his comics costume.
Other actors who portrayed mutants were: Meiling Melançon as Psylocke, a mutant with the ability to teleport herself through areas of shadow; Omahyra Mota as Arclight, a mutant who has the ability to generate shock waves of concussive force; Ken Leung as Kid Omega, a mutant with the ability to eject spikes from his body, most notably his face (though the character resembles the comic books' character Quill however, the official cast credits read "Kid Omega"); and Cameron Bright as Jimmy / Leech, a mutant who has the ability to neutralize the powers of nearby mutants. Various characters were included at the suggestion of editor Mark Helfrich, who brought Marvel's X-Men Encyclopedia to director Brett Ratner, searching for mutants who could make appearance. Mark Helfrich portrays an unnamed mutant with ash-gray skin. These include Phat, a mutant that is a very large man who can slim down to fit in a smaller space (played by two actors, Via Saleaumua – "large mode" – and Richard Yee – "small mode"); Spike (played by Lance Gibson), a mutant who battles Wolverine in the forest by extruding bony spikes from his flesh – the character was added because the editing team felt that the original cut of the scene portrayed Logan as a cold-blooded killer, which could be changed if another mutant attacked Wolverine before he struck the Brotherhood and Glob Herman (played by Clayton Dean Watmough), a mutant with transparent skin. Various other mutants make cameos at the X-Mansion; Shauna Kain and Kea Wong reprised their cameo roles as Siryn and Jubilee respectively, and three identical girls in the background in one scene are a reference to the Stepford Cuckoos. Olivia Williams portrays Moira MacTaggert. X-Men co-creator Stan Lee and writer Chris Claremont have cameos in the film's opening scene as the neighbors of young Jean Grey. The sergeant directing defensive preparations before the Brotherhood assaults Alcatraz Island is played by R. Lee Ermey. Lloyd Adams portrays the green-skinned mutant that climbs the guard tower on Alcatraz. Many fans believed this was Toad however, the credits list him as lizard man and Brett Ratner confirmed it was Anole. Avalanche and Vanisher also appear however it is not known who portrayed them.
Bryan Singer, the director of the first two X-Men films, left the project in July 2004 in favor of developing Superman Returns. Singer stated that he "didn't fully have X-Men 3 in my mind" in contrast to a fully formed idea for a Superman film and interest in joining that franchise. By the time of his departure, Singer had only produced a partial story treatment with X2 screenwriters Dan Harris and Michael Dougherty, who accompanied him to Superman Returns. The treatment focused on Jean Grey's resurrection, which would also introduce the villainness Emma Frost, a role intended for Sigourney Weaver. Frost was an empath manipulating Jean's emotions in the treatment and, like the finished film, Magneto desires to control her. Overwhelmed by her powers, Jean kills herself, but Jean's spirit survives and becomes a god-like creature, which Dougherty compared to the star child in A Space Odyssey.
New contracts for returning cast members were made, as the actors and actresses had signed for only two films. Hugh Jackman's contract included the approval of director, initially offering the position to Darren Aronofsky, with whom he had just finished filming on The Fountain. Joss Whedon, whose comic book "Gifted" was integrated into the script's plot, turned down the offer because he was working on a Wonder Woman film. Rob Bowman and Alex Proyas were also rumored to be up for consideration, though Proyas personally turned it down, citing feuds with 20th Century Fox president Thomas Rothman while producing I, Robot. Zack Snyder was also approached, but he was already committed to 300. Peter Berg was also considered to direct the film but he too turned down the job. In February 2005, with still no director hired, Fox announced a May 5, 2006, release date, with filming to start in July 2005 in Vancouver. One month later, the studio signed Matthew Vaughn to direct, and pushed the release date three weeks to May 26, Memorial Day weekend. Vaughn cast Kelsey Grammer as Beast, Dania Ramirez as Callisto, and Vinnie Jones as Juggernaut, but family issues led him to withdraw before filming began. Vaughn was also cautious of the tight deadlines imposed by Fox, stating that he "didn't have the time to make the movie that I wanted to make". John Moore was also considered to direct the film at one point.
Brett Ratner, who was previously considered to direct X-Men in 1996, replaced Vaughn during pre-production. Ratner said he was surprised to get an invitation, as he thought he would have no chance to do a comic-book film after the cancelled Superman: Flyby for Warner Bros. With a limited knowledge of the X-Men mythos, Ratner trusted his writers on doing something faithful to the comics, having the script drawing all of its scenes from the original Marvel publications.
Simon Kinberg, who had worked in other two Marvel adaptations for Fox, Fantastic Four and Elektra, was hired as writer for X-Men 3 in August 2004. X2 co-writer Zak Penn was separately working on his own draft, and the two joined forces for a combined screenplay in January 2005. Kinberg wanted "The Dark Phoenix Saga" to be the emotional plot of the film, while "Gifted" would serve as the political focus. The duo had seven months to complete The Last Stand's script, and during the first week of work completed the first eighty pages, consisting of the first two-thirds of the plot. This incomplete draft was leaked to Ain't It Cool News, who proceeded to write a negative review.
The writers had to fight Fox's executives to retain the Phoenix plot, as the studio only wanted the cure story as it provided a reason for Magneto's conflict with the X-Men. Still the disputes made them not add much for Jean Grey to do in most of the film's second half, as the executives considered the tone of the Phoenix story too dark for a mainstream summer movie, and that its appeal would be limited to hardcore fans rather than a general audience. Penn defended the divergences from the original Dark Phoenix stories, stating that the Phoenix was not a firebird-shaped cosmic force "because it doesn't fit into the world," and that Cyclops did not have as much screentime as Wolverine because the latter was more popular and "with Cyclops, you can't see his eyes. It's a harder character to relate to for the audience." Killing Cyclops was Fox's decision, based on the availability of actor James Marsden, who was cast in Singer's Superman Returns. The studio considered killing him off-screen with a dialogue reference, but Kinberg and Penn insisted that Jean kill him, emphasizing their relationship. Xavier's death was intended to match the impact of Spock's demise in Star Trek II: The Wrath of Khan, as Fox felt the script called for a dramatic turning point. Kinberg and Penn were originally cautious, but grew to like the idea of killing off Xavier. They decided to write a post-credits scene suggesting the character's return for a sequel.
As the studio was simultaneously developing X-Men Origins: Wolverine, limitations were set on which mutants could be used for cameo appearances in X-Men 3 in an attempt to avoid risking character development for Wolverine. Gambit was considered for both the convoy scene being freed by Magneto and the Battle of Alcatraz along with the X-Men, but the writers did not want to introduce a fan favorite character and "not be able to do him justice." Kinberg reasoned, "there just wasn't enough space", and considered Gambit would only work with as much screentime as Beast. Alan Cumming had been uncomfortable with the long hours he had to take with the prosthetic makeup as Nightcrawler in X2, but still planned to return for the sequel. The part of Nightcrawler was so minimal, however, that the studio felt it was not worthwhile to go through the long and costly makeup process, and the character was cut. Kinberg felt that "there wasn't much left to do with the character. It also felt like he might tread a little bit on the terrain of Beast, in terms of similarities in the characters and their political standpoints in terms of dealing with their mutancy." Nightcrawler's absence was later explained in the tie-in video game. The introdutory scenes tried to emulate the Auschwitz opener for the first film, going with different scenes that resonated later in the plot instead of an action scene like in most blockbusters. Afterwards came a scene in the Danger Room, which was considered for the previous X-Men films but never included for budget and writing concerns. The writers tried to make the simulation not feel extraneous by showcasing some of the character conflicts and abilities in a "Days of Future Past"-inspired battle with a Sentinel. Another repurposed scene was Magneto attacking the convoy to free Mystique, Madrox and Juggernaut, which Penn had previously envisioned for X2.
Ratner collaborated with Penn and Kinberg in rearranging the plot structure of the film. Originally, the Golden Gate Bridge sequence was in the middle of the film, where the moved bridge was used by Magneto to free mutants being held prisoners on Alcatraz, and the climax was set in Washington, D.C.. Ratner felt too many recent action films, such as Planet of the Apes and X2 itself, had their ending in Washington, and the Golden Gate sequence "would be the biggest sequence in my entire career", and suggested to instead put the Worthington laboratory in Alcatraz, along with "creating a face for the cure", which became the character of Jimmy/Leech. Kinberg agreed, as he previously argued with Penn about "blowing so many things early in the movie".
X-Men: The Last Stand began shooting in August 2005 and wrapped in January 2006. Much of the film was shot at Vancouver Film Studios, the same location of X2. Locations included the Hatley Park National Historic Site and Royal Roads University, which doubled for the X-Mansion. An old lumber mill next to the Fraser River doubled as Alcatraz Island. The tight schedule made Ratner "begin post-production the day I started shooting," sending the scenes he had just filmed to his editors. The editing team was led by Mark Helfrich, who had edited all of Ratner's films, assisted by Mark Goldblatt in the action scenes and Julia Wong with effects-heavy footage.
According to associate producer Dave Gordon, "This is the biggest production ever filmed in Canada. It used to be X2, now it's X3." The $210 million budget also made The Last Stand the most expensive film to be made at the time. The film's record would be first broken by Pirates of the Caribbean: Dead Man's Chest's $225 million budget. The original cinematographer was Philippe Rousselot, who eventually opted to depart production. Dante Spinotti, a frequent collaborator of Ratner, replaced him, with assistance of J. Michael Muro. Fox Filmed Entertainment co-chairmen Thomas Rothman and Jim Gianopulos debated whether Rogue should give Iceman a passionate kiss at the film's end or simply hold his hand. The two executives screened The Last Stand for their daughters, as well as the studio's female marketing executives, and the hand holding prevailed. Gianopulos stated that the kissing "was all about sex, and we didn't want that." A strong campaign of secrecy about the script was enforced by Ratner and the writers. Even the actors had problems with getting full screenplays, the call sheets did not reveal all the characters, and many scenes were shot in varied ways. Both of the ending scenes were not included on the shooting script, with Ratner taking a small crew during one day's lunch time to film the post-credits scene with Xavier, and later going to London to film Magneto in the park.
In 2014, Kinberg said of the wobbling chess piece at the end of the film, "There is a scene before the credits where Magneto's playing chess, and you see that he can just make the chess piece move, so there's a hint that he's starting to regain his powers. The leap from there was that cure from The Last Stand didn't work exactly the way they thought it would, and so we just leaped forward however many years, and he's got his powers back."
To make sure the visual effects were made in just one year and without exceeding the budget, special effects supervisor John Bruno shipped the 900 effects shots to eleven companies in four countries – United States, New Zealand, United Kingdom and Canada – and did extensive previsualization. Their work begun in April 2005, before the director Brett Ratner had even been announced, and Bruno made sure to emphasize practical effects, "shoot as many practical elements as possible, and only use CG when we had to." For instance, complex wirework rigs were employed which enabled the actors to do some stunts without resorting to digital doubles, including a computer controlled flying rig from Cirque Du Soleil for Angel's flight, and one for Halle Berry's flying spins.
Bruno estimates one-sixth of the effects budget was spent on the Golden Gate Bridge scene, which employed both a miniature of the bridge and computer graphics. The effects team had to work without reference footage due to the city of San Francisco vetting any filming in the actual bridge, including aerial shooting as the area has restrictions on flying helicopters. Framestore had further challenges in matching the varied weather conditions across the film's plates. As compositing supervisor Matt Twyford detailed, "the elements consisted of cold, rainy night live-action footage from Vancouver, sunny day miniature elements, traditional misty day background plates of San Francisco, and of course the CG bridge and fx elements." Another miniature was for the Grey home, which had a destructable equivalent matched the Canadian location and also had a digital equivalent. A notable effect was the "digital skin-grafting", which rejuvenated the faces of senior actors Patrick Stewart and Ian McKellen, made by the Brothers Strause's Lola Visual Effects. Bruno made sure to ask the atomization made by Phoenix was not too vivid and gruesome, instead resembling oatmeal.
Ratner, a fan of John Powell's work in The Bourne Identity, invited Powell to write the music for The Last Stand. Powell was unsure if the Bourne work was "the kind of score that would fit the film" and Fox got reluctant on the composer's availability given he was already scoring Ice Age: The Meltdown at the time of Ratner's contact. But Powell finished the Ice Age score early to accept the X-Men job even if it meant a tighter schedule. Powell included references to the score from the previous two films as "it all had to be in the same family, and the same language". The Phoenix theme used lyrics from Benjamin Britten's Requiem Mass for the choir parts. A soundtrack album was released on May 23, 2006.
The marketing for The Last Stand was darker and more ambiguous compared to the two predecessors. Fox president Tom Rothman declared that the decision was made so the film would "be different from all of the other movies in the summer," with a campaign that "wanted people to stop and not have it be so immediately apparent that we're selling a movie. We're interested in selling an emotion and an idea." The film's official website was launched in October 2005. The teaser trailer release with King Kong the following December was done in conjunction with the studio releasing the film's first official screen shots of the film to USA Today. Diamond Select Toys created a toy line, scanning the actors from the film with likenesses for the first time in the trilogy. Additional product tie-ins came with Harley-Davidson and 7-Eleven. A seven-minute sneak peek aired on Fox Broadcasting two weeks before the film's theatrical release.
Del Rey Books published a novelization of the film, written by comic book writer Chris Claremont, while Newmarket Press published The Art of X-Men: The Last Stand: From Concept to Feature Film. Claremont also worked on Activision's tie-in video game, X-Men: The Official Game, doing the script along with screenwriter Zak Penn. The game's story bridges the events between X2 and The Last Stand, featuring Wolverine, Iceman and Nightcrawler as playable characters, voiced by their film portrayers Hugh Jackman, Shawn Ashmore, and Alan Cumming. Patrick Stewart also appears as Professor X. The game was released to negative reviews and eventually underperformed commercially.
X-Men: The Last Stand premiered at an out-of-competition event of the 2006 Cannes Film Festival on May 22, 2006. Two days later, Hugh Jackman, Halle Berry and Kelsey Grammer attended an advance screening at USS Kearsarge (LHD-3), as the ship was en route to New York City for Fleet Week. The film was released in the United States on May 26, 2006, in 3,690 theaters, while also opening in 95 international markets that same weekend.
On Rotten Tomatoes, the film has an approval rating of 58% based on 232 reviews, with an average rating of 5.9/10. The site's critical consensus reads, "X-Men: The Last Stand provides plenty of mutant action for fans of the franchise, even if it does so at the expense of its predecessors' deeper moments." At Metacritic, the film has a score of 58 out of 100, based on 38 critics, indicating "mixed or average reviews". Audiences polled by CinemaScore gave the film an average grade of "A–" on an A+ to F scale.
Ebert and Roeper gave the film a "two thumbs up" rating, with Roger Ebert saying, "I liked the action, I liked the absurdity, I liked the incongruous use and misuse of mutant powers, and I especially liked the way it introduces all of those political issues and lets them fight it out with the special effects." Stephanie Zacharek of Salon.com gave it a mixed review, noting that it was "only half a mess", and that Ratner "could have stuck a bit more closely to the 'Dark Phoenix' narrative than he did." However, Zacharek did note that that third act captured some of the original story's "majesty". Famke Janssen's performance was praised by critics and audiences. Also impressed with Janssen's performance was Total Film, who said, "Playing the super-freaky mind-control goddess like GoldenEye's Xenia Onatopp's all-powerful psycho sister, her scenes – particularly that one with the house – crackle with energy and tragedy. If only the rest of X3 had followed suit."
Justin Chang of Variety said the film was "a wham-bam sequel noticeably lacking in the pop gravitas, moody atmospherics, and emotional weight that made the first two Marvel comicbook adaptations so rousingly successful." Frank Lovece of Film Journal International said, "A risk-taking script with genuine consequences elevates this above the lackluster direction of Brett Ratner, whose competent mechanics move the story efficiently but with very little soul." Lisa Schwarzbaum of Entertainment Weekly called it a ""diminished sequel, a brute-force enterprise" and said it was an example of "what happens when movies are confused with sandwich shops as franchise opportunities". The Minneapolis Star Tribune characterized Ratner's approach as "Forget subtlety! Let's blow things up!" David Edelstein of New York magazine called it "just another big-budget B-movie. It's a fast and enjoyable B-movie, though." Foreshadowing X-Men: First Class, Peter Travers of Rolling Stone said, "Last stand? My ass. Billed as the climax of a trilogy, the third and weakest chapter in the X-Men series is a blatant attempt to prove there is still life in the franchise. And there is: just enough to pull a Star Trek and spawn a Next Generation saga."
Writer Kinberg would later state that "there are a lot of things about 'X3' that I love and there are a lot of things that I regret", detailing that he would have preferred the Dark Phoenix as the main plotline and "I would have fought harder" for that, considering that at the period "the darkness of her story was a little bit daunting on a huge $200 million studio movie" leading Fox to ask for rewrites. Previous X-Men director Bryan Singer declared that The Last Stand "isn't what I would have done" and he was dissatisfied with the busy plot and excessive character deaths, but Singer still liked some parts of the movie, such as Ellen Page's casting – leading Singer to bring her back as Kitty Pryde in X-Men: Days of Future Past – and the scenes with Leech, which he described as "really sweet moments". Matthew Vaughn, who was attached as director before dropping out, criticized Ratner's direction: "I could have done something with far more emotion and heart. I'm probably going to be told off for saying that, but I genuinely believe it." While promoting his own installment of the franchise, 2011's X-Men: First Class, Vaughn would say regarding The Last Stand that "I storyboarded the whole bloody film, did the script. My X3 would have been 40 minutes longer. They didn't let the emotions and the drama play in that film. It became wall-to-wall noise and drama. I would have let it breathe and given far more dramatic elements to it."
The film broke the Memorial Day weekend record with $102,750,665 in its four-day opening weekend. The film's release was also a new single-day record for Friday openings. The opening weekend gross was surpassed six weeks later by Pirates of the Caribbean: Dead Man's Chest, making The Last Stand's opening the second-highest of 2006. Internationally, The Last Stand topped the box office in 26 countries with a total gross of $76.1 million overall, but suffered competition from The Da Vinci Code, which retained the top spot in most markets, and beat The Last Stand in international gross that weekend with $91 million. The film's second weekend dropped 67 percent to $34 million, which was the steepest post-Memorial Day opening drop on record. X-Men: The Last Stand eventually grossed $234,362,462 in the domestic box office and $224,997,093 internationally, for a worldwide total of $459,359,555, the fourth-highest in domestic grosses and seventh-highest worldwide for 2006. X-Men: The Last Stand was also the highest-grossing film in the franchise, until it was surpassed by X-Men: Days of Future Past eight years later.
X-Men: The Last Stand was released on October 3, 2006, on DVD and VHS. It was available in three editions: single-disc, two-disc, and a trilogy box set with the previous two films. Extras included three alternative endings, each with optional commentary by director Ratner; 10 deleted scenes; audio commentaries from Ratner, the writers and the producers; and two hidden Easter eggs. The two-disc edition came with a 100-page commemorative comic book with a new story written by X-Men co-creator Stan Lee, his first original Marvel comic book in five years. The DVD sold 2.6 million units in its first day, exceeding Fox's expectations, and sold a total 5 million in its first week. A Blu-ray edition was issued in November 2006.
In February 2006, Ratner said that The Last Stand could be the final X-Men film: "We wanted to make sure the audiences knew that this was a trilogy. Even though they weren't made together like Lord of the Rings, this is really closure for the X-Men series. … This is the last stand for sure."
However, the next two X-Men films, X-Men Origins: Wolverine (2009) and X-Men: First Class (2011) were instead prequels that took place before the events of the first X-Men movie. The first installment set chronologically after The Last Stand was The Wolverine, released in 2013. A stand-alone sequel, The Wolverine shows Logan heading for Japan to escape the memories of what occurred during The Last Stand. Hugh Jackman and Famke Janssen reprised their roles, while Ian McKellen and Patrick Stewart appear in a mid-credits scene.
X-Men: Days of Future Past, the sequel to First Class, was released on May 23, 2014, with Jackman, Berry, Stewart, McKellen, Paquin, Page, Ashmore, Cudmore, Grammer, Janssen, and Marsden returning in their respective roles. The plot, inspired by the arc "Days of Future Past", begins in a dystopian future years after The Last Stand, and Wolverine's consciousness is sent back into his 1973 self so he could guide the past Xavier and Magneto into preventing the catastrophe. The events of the film end up retroactively changing the continuity of the series, erasing key events in all previous films (except First Class) within series including The Last Stand; with the ending set in an altered timeline where Jean and Cyclops are still alive.
