Late in the movie during backstage scenes for the final competition several extras in the background of one shot are wearing University of Washington cheerleader uniforms. They are clearly out of place at this "High School" competition.
When Torrance is staying at Missy's house, she walks into Cliff's room while he's playing the guitar. His left hand never changes position on the neck, yet he's "improvising" a constant succession of chords.
In the gym, after Aaron sells Torrance out to Courtney and Whitney, and she declines to retire her position, when the squad decides to Learn a New Routine for Nationals, Torrance says to Courtney and Whitney, "How about it, girls?". She then looks in a direction that would put Courtney and Whitney in the bleachers several rows up instead of five feet away from her.
When Torrance, Jan and Les pick up Missy in Les' jeep, Missy and Torrance have the short tank tops of their cheerleading outfit on. At the football game, however, which is where they are headed in the jeep, all the female cheerleaders have on long sleeve shirt tops.
Whenever Cliff appears on screen, in some shots, he appears to have a tattoo of a roman numeral on his upper left bicep. In the scene where Missy is practicing her cheers in their living room and Cliff walks in and makes fun of her, his 'tattoo' is severely faded and almost completely washed off from his skin. However, in the final scenes in the movie, during the shot of Cliff in the crowd rocking out to the Toros' routine at Nationals, Cliff's arm is raised and his tattoo is once again visible and freshly filled in. It *is* possible that Cliff could have just liked to draw fake tattoos on his body like his sister did in the audition scene, but being as the film takes place over a several month period, the odds of him continually drawing the same tattoo in the same spot is highly unlikely.
Right before the "You believed in me" scene, Torrance is handed a paper by some of the other cheerleaders, but when she walks off to tell Cliff that she broke up with her boyfriend she no longer has the paper.
The position of Cliff's car when he is at Torrance's house changes. In the first shot of the car, it is far down the road on the left side of the street, facing the house. In the second shot, it is on the right side of the street, much closer to the house, facing the opposite direction.
In the auditions scene, the girl starts off with a top that covers three-quarters of her midriff and has a design on it. By the time she's on the table, she has only her bra on (see Alternate Versions).
During the Clovers' final routine one of the girls that runs by has a belly button ring. No body piercings are allowed during cheerleading competitions, and deductions would result from not following the rules. Similarly, they are wearing body glitter, also illegal.
The Toros do a "fly over" in their routine. (A "fly over" is when a flyer is flipped off a pyramid.) A "fly over" is a highly illegal dismount in high school competition and results in disqualification.
The Toros and Clovers don't seem to have a coach. At High School level all routines must be approved by the coach. Also no team would be permitted to attend a competition unless the coach is present. (As the other teams do.)
At one point, Torrance mentions that they have less than three weeks before Nationals and "since the football team sucks, they can use night games for practice". Earlier she said that Nationals were February 10, which would make it mid-January when she gives her "Three Weeks 'til Nationals" speech. In January, high school football season would be long since over.
When Torrance drops the spirit stick, it is a red, white and
blue wooden stick. This is an NCA spirit stick and they are at a UCA camp. UCA's spirit sticks are blue, yellow and white and are hollow plastic tubes with end caps.
The high school in the football game where Torrance has "cheer sex" with Cliff, the Toros are playing Costa Mesa High School, although the colors were Estancia High School's colors. Estancia is the rival school to Costa Mesa.
At one point in the movie, it is announced that 50 squads have made it to Nationals. This seems to imply one team from every state. However, in California, both the current top in state and last year's winners are able to attend Nationals. This would allow for a total of 51 teams.
One of the cheerleaders from the Toros appears also to be a cheerleader in the Clovers (she is very short with brown hair). They are, in fact, different girls, played by twin sisters. It still seems improbable that they would attend different high schools more than 100 miles apart, but this is not impossible.
After they decide to continue to go to Nationals, you see the
team practicing the Wolves' Wall. In this scene, you can see Carter, who broke her leg, and you can easily see that everyone is in the same clothes that they were in after Torrance was voted Captain.
The goof item below may give away important plot points.
In the end scene when the East Compton Clovers are presented with a check for twenty thousand dollars, in the top left corner of the check it says "Universal Cheerleading Association," when UCA really stands for Universal Cheerleaders Association. Also teams do not normally receive money for winning UCA Nationals.
