The film is an inside look at the world of Roller Games, then a popular league sport-entertainment, a more theatrical version of Roller Derby.
The story focuses on K.C. Carr (Welch) who has just left her former team in Kansas City, Missouri to start her life as a single mother over again in Portland, Oregon with a team called the Portland Loggers. Loggers' owner Burt Henry (McCarthy) is clearly interested in her, and K.C. and Burt date. But Burt has a rather ruthless side to him: he trades away K.C.'s best friend on the team, and when he sees that star male skater "Horrible" Hank Hopkins is interested in her, he manipulates the audience into booing Hopkins, causing him to go crazy and lose his job. Henry's endgame is to set up a match race between K.C. and her teammate and rival Jackie Burdette (Kallianiotes), with K.C. deliberately losing so that she can join Henry at a new team he's setting up in Chicago. But K.C. doesn't trust Henry anymore (or his promises to let her bring her daughter along) and wins the match race.Raquel Welch as K.C. Carr

The film was written by Barry Sandler as a UCLA MA Thesis, with Welch in mind for the lead. "Raquel was a huge star at the time--kind like the pop culture goddess," recalled Sandler. "I just thought it would be great to see her as a roller derby queen; it seemed like a perfect meshing of pop culture with that role."
Although Sandler and Welch shared the same agent, ICM, he was a very new screenwriter and was unsure if the script would actually get read. He delivered a copy personally to the house Welch then shared with her husband and manager, Patrick Curtis. Curtis bought the script in March 1971 for their production company, Curtwel Productions. "She was a huge star at the time, and that meant if she wanted to do it, the movie would get made," said Sandler.
"I believe that he had me in mind when he wrote it," said Welch. "The girl is more than a little bitchy."
Sandler says the original script was very different to what the movie became:
[It was] a dark, gritty, character piece, more in the vein of Requiem for a Heavyweight. It’s about this young woman from Kansas City who goes out to Hollywood dreaming of fame and fortune, making it in the movies, and she’s really not good enough to do so, but she’s desperate to make her name and to get attention. She struggles and struggles, and never makes it, and then one day, she meets this kind of beat up, bruised up, burnt-out ex roller derby queen who kind of takes her under her wing and coaches her, and tries to get her involved in the roller derby. It sort of shows her becoming a roller derby star, and the irony is that she makes it in the roller derby, but as a black-trophy...as a bad girl who gets hissed at, beat up, and spit on every week. The irony is that she is able to find the stardom she desperately yearned for, but not as a movie star--as a star on the roller derby track getting booed at and spit at every week. And so it’s kind of dark, and much grittier and different, kind of almost along the lines of Midnight Cowboy.
The film was originally going to be made at Warner Bros, then at United Artists. Eventually Welch divorced Curtis and made the film for her own company in association with Artists Entertainment Complex and Levy-Gardner-Laven. The film was part-financed and distributed by Metro-Goldwyn-Mayer, whose president, James T. Aubrey, was romantically linked with Welch for a time.
Over the course of moving from studio to studio, the script was heavily rewritten. Sandler later said if the film had been made at Warner Bros, "they would have stuck to" the original conception
Warner Brothers was a much more adventurous studio at the time. They were making The Devils and A Clockwork Orange, Performance…they stuck with those kinds of movies.... MGM wanted to sell Raquel Welch in a tight roller derby jersey, running around the track. Listen, they weren’t stupid, they were smart to do that. It certainly made them a lot of money, and it would have been a much riskier project to go the other way. They weren’t sure whether Raquel could pull it off. I think she could have, but they wanted to play it much safer and go with a much more straight-on roller derby story. So, the film was made like that, and I think it’s pretty good, but it’s a different kind of movie than the version I envisioned.
Raquel Welch discussed her character in detail to the press:
The motivation of the character I play is simply to make a buck in life and to attain a sense of identity. There's a futility in what she does. The shape of the track is her life, round and round, going nowhere. But the pros, the real skaters who worked with me, they were terrific. Most of them suffer from the same image I do. They're on skates, they're padded up, they're on a raised track. Most people tend to think of these girls as Amazons. But most of them are even smaller than me. They're not as muscular or as butch as you'd expect. I have a similar problem. Most people are disappointed if the door hinges don't shatter off when I walk into a room.
"It's all set up, as everyone knows," said Welch of skating. "It's too bad it couldn't be a more legitimate sport. The skaters have great athletic ability. I'm not much of an athlete... For the film I had to learn to skate again. I hadn't skated since I was seven."
Filming was to have started in February 1972. Welch practiced skating for several months, training with pro teams, wearing a wig and dark glasses and posing as a journalist looking into a story. In January a rink was constructed on the MGM soundstage, enabling Welch to practise daily. She broke her right wrist during a speed skating session, forcing shooting to be put back eight weeks until April.
Filming took place in Portland, Oregon. Two weeks into the shoot Welch suffered a cut lip and swollen face during a fight scene with co-star Helena Kallianiotes. An MGM spokesman said the two actors "got carried away" and Welch "got slugged". Welch later said she also bruised her knees, got a spasm in her trapezius, had some hematomas on her head and several headaches.
The film used real life roller derby stars as extras, such as John Hall and Danny "Carrot Top" Reilly from the L. A. Thunderbirds. Real roller derby venues in Kansas City, Fresno, and Portland were also used for key scenes.
"The film was fun," said Welch. "I like to be in physical pictures. And the Roller Games is a microcosm of this country, the kind of thing we create."
The game is almost show business, it's a carnival atmosphere, but I can understand its popularity. Most of the spectators are basic people and there's something cathartic about watching people get dumped. The yelling creates a certain kind of intensity. The type of violence draws you in, makes you involved. The skaters are tough but I think all women are tough. The skaters aren't any tougher than most of the women in the world, underneath. Skating is a batchy, sweaty, funky life. I don't want to do another film about it. I've done my number. But I enjoyed it.
Welch later said this was the first of her films that she actually liked.
The songwriter Phil Ochs wrote a song with the same title that he had intended as title song for the film, but was rejected by Metro-Goldwyn-Mayer. Ochs had A&M Records issue the song as a single anyway, and hoped to publicly debut the song at the Los Angeles Thunderbirds' track during a Roller Games television taping at Los Angeles' Olympic Auditorium, as many of the Thunderbirds skaters had appeared in the movie as extras and announcer Dick Lane had a small speaking role; Thunderbirds owner Bill Griffiths Sr. rejected that idea as well. Don Ellis contributed the score of the film.
The New York Times wrote that:
Jerrold Freedman has directed "Kansas City Bomber" with an eye to hard-hitting action and gutsy detail. But I don't think his eye is really sharp enough or fast enough or even wide enough open. His roller-games scenes seem authentic but rather unexciting; and his major stylistic contribution is to indulge a penchant for zooming his camera back, leaving characters trapped behind windows in pretentious and often ludicrous dramatic isolation.... The film's one incredible performance comes from Helena Kailianiotes, as Jackie Burdette. Slouching sullenly in doorways, staring moodily into space, cadging booze from a bottle hidden in a skating boot, she goes to the dogs with an inappropriate passion rich enough to suggest an over-the-hill Sarah Bernhardt being traded off to the minors by the Comédie Française.
Gene Siskel thought the movie was "more than good fun. It's a gas."
Kevin Thomas of The Los Angeles Times thought Welch "comes through with a characterization as unexpected as it is persuasive" and said the film "is a well observed slice of contemporary Americana" which "marks Raquel Welch's coming of age as an actress and is a personal triumph for her after surviving more rotten movies than anyone would care to remember."
Joyce Haber called it one of the worst films of 1972.
James Aubrey later claimed the film was one of MGM's most successful releases of 1972, after Shaft and Skyjacked. The success of the film caused the share price of Artist Entertainment Complex to rise. Barry Sandler says the film was profitable and proved lucrative for him.
Helena Kallianiotes was nominated for a Golden Globe for "Best Supporting Actress – Motion Picture"
The film was heavily publicized during filming. This inspired Roger Corman to finance an exploitation film set in the world of roller derbies, Unholy Rollers.
Welch sent up the film as part of her Las Vegas act in late 1972.
Welch later said she was "good" in the film just as she was good in Myra Breckenridge and The Last of Sheila, "but being good in a bad film doesn't do anything for your career." In 1978 she said the film was one of the few in her career with which she was happy, the others being L'Animal and The Three Musketeers.
