The cartoon opens with a short special, celebrating Bugs Bunny's 51½ Anniversary. Once that is finished, what happened earlier that day is shown, with a backstage look at the characters (featuring 3D rendering of the scenery). Bugs is shown rehearsing his one line in the special. Elmer Fudd is shown trying to use minoxidil to regrow his hair. Daffy Duck and Yosemite Sam are shown only begrudgingly going along with the act, complaining non-stop until called to their places by the director. They attempt a performance, which results in a series of animated "bloopers".
Bugs Bunny begins to dance, but the music is slightly out of tune and the record skips. He then dryly looks at the camera and says, "Ehh...What's up, Doc?" in an annoyed and sarcastic voice. The director and producers laugh as Bugs walks off stage. He then peeks back in to say "Monotonous, isn't it?", which gets the director and producers laughing again and right when the screen fades to black, the record scratches.
Bugs halts the performance midway, having noticed a loose floorboard on the stage. He then suggests moving the action back and readjusting the camera.
Bugs misses the cane when it flies out.
The cane is thrown before Bugs is ready to catch it.
While waiting for the cane to be thrown, it becomes clear that Daffy Duck has refused to throw it to Bugs. According to Daffy, his contract states that he is not supposed to throw canes to rabbits, resulting in the director agreeing to have someone else throw it in Daffy's place.
Daffy enters the stage at the exact time that Bugs does, saying that he thought it was a vast improvement as he walks away, only to bump his head on the boom mike.
Daffy does not appear when he is supposed to. Offstage, Daffy is heard telling Bugs, the director and the producers to wait, followed by the sound of a toilet flushing. As Daffy then rushes onto the stage dancing, the director yells, "Cut! CUT! CUT!"
Elmer Fudd fires a real gun as opposed to a prop, grazing Daffy's head. Bugs scolds him, but Elmer responds that he thought that it would be "a gweat, big birthday surpwise" if he finally shot Bugs "after 51 ½ years of twying". Daffy starts yelling at Elmer for not using the prop gun and neglects Bugs's insistence on cutting. As he walks away telling Elmer to expect his lawyers to call him, he steps on the loose board Bugs had avoided earlier, and the board strikes him in the face and goes through his beak. When Bugs asks if they can cut now, Daffy grumbles, "You smug son of a—" and is then cut off.
Daffy dances onto the stage with the board still stuck to his face. When he pulls it off, he yanks his beak off as well in the process, but continues speaking and where his beak was, a mouth appears, though he fails to notice it.
Everything plays out correctly until Yosemite Sam emerges from the cake with a scowl on his face and two Cowgirls come up and spruce him up. The director instructs him to act cheerful for the next take. Yosemite Sam goes back into the cake, mumbling "But I hates rabbits".
The spectacular performance is done perfectly, except for one thing, as Bugs puts it – there were supposed to be five rockets. A fifth rocket attached to Sam's belt sends him flying about before crashing into the camera. He then yells at Bugs, calling him a "low down flop-eared son of a kangaroo", along with his usual cursing (which lasts throughout the credits) before being knocked out by an unseen glass object. Bugs then suggests that what had just happened can be fixed in the editing before one of the producers asks, "Can we go to lunch now?"Jeff Bergman as Bugs Bunny, Daffy Duck, Elmer Fudd, Yosemite SamGordon Hunt as Man in Audience, Movers, Director
(Blooper) Bunny was produced at a time when newer Looney Tunes shorts were being released to introduce the Warner cartoon characters to a younger, more modern generation — a process that was, thanks to the tepid reception of 2003's Looney Tunes: Back in Action, eventually discontinued for some time from 2004 to 2009. The film was animated using a combination of both new computer technology and traditional cel animation — a first for a Warner Bros. cartoon — with three-dimensional rendering distorting the background in the "backstage" scenes to give the appearance of a handicam being used. The first "backstage" scene in the film, a sequence that goes on for nearly a minute and a half without a cut, is, according to co-director Greg Ford, one of the single longest uninterrupted shots ever attempted in animated cartoons.
The short features several direct references to some of the previous output of Warner Bros. animation department. During the first, aforementioned "backstage" scene, the name of Bosko, the first true Looney Tunes star, can be seen on one of the dressing room doors for a few frames (ironically, the Warner Bros. studio did not own the rights to Bosko at the time). Midway through the film, there is also a deliberate homage to the "Hunting Trilogy" made popular by Chuck Jones, of whom Ford reportedly holds great admiration. Additionally, during the end credits, the theme song of One Froggy Evening, another Chuck Jones creation, can be heard.
Suppression, rediscovery, and subsequent reputation
(Blooper) Bunny is a self-parody of some of the specials produced for Bugs Bunny's 50th anniversary the previous year, 1990. The short, however, never received its intended theatrical release and was shelved for several years.
Jonathan Rosenbaum, in a review for Chicago Reader, noted: "Ironically, Invasion of the Bunny Snatchers, another Bugs Bunny cartoon directed at the same time by the same rebellious duo, Greg Ford and Terry Lennon, is even more directly critical of studio greed, yet it got a pass and wound up on the TV special Bugs Bunny's Creature Features, perhaps because it was less formally transgressive."
(Blooper) Bunny would not receive a television premiere until 1997, after Cartoon Network discovered the film sitting unseen in the vaults. It is featured on the Looney Tunes Golden Collection: Volume 1, as of 2003, along with an optional audio commentary by co-director Greg Ford.
Jules Faber, in a review for DVD.net, lauded the cartoon as a "highlight" and elaborated further: "Blooper Bunny: Bugs Bunny's 51½ Anniversary is a clever little blooper reel created in 1991 and utilising some brilliantly conceived early 3D rendering making a very funny behind the scenes mockumentary." Chicago Reader also gave the film a positive mention, saying:
Much of what's funny about Blooper Bunny is the temperament of the aging cast: Bugs rehearsing his opening line, "Gosh, I'm so unimportant," over and over; Elmer still trying to grow hair with tonic; Daffy insanely jealous about being upstaged and threatening to have "my people" talk to "your people"; and Sam grouchily declaring as he's being forklifted onstage that he couldn't care less how old Bugs is — he still hates rabbits.
Dawn Taylor, in a review for The DVD Journal, said: "it has some very funny moments, and falls completely flat in others."Written by
