During the filming of the scene when Torrance, Missy, Jan and Les carpool to a football game, a driver, angry that the film's motorcade was making him late for dinner, attempted to drive the camera truck off the road. It appears the character of Les is just an overly cautious driver who keeps checking his side mirrors. Huntley Ritter is really watching Mr. Road Rage get pulled over by the Highway Patrol.
The high school pictured in the movie is actually San Diego State University. A statue of the founder of the university can be seen in the shot at Missy's car before Torrance and Missy go to see the Clovers.
The Advanced Chemistry textbook that Torrance is studying is not a real book at all. The PHD writer is actually the Assistant Propmaster's name. Though not real, the book is credited at the end of the film as an actual book that was cleared for use.
During the first football game scene, the male cheerleaders behind Missy (Eliza Dushku) are not making the Torro "bull" hand signal like the rest of the cheer team. Instead, they are making "the shocker" hand signal.
The Toros gym scenes were filmed at Academy of Our Lady of Peace (OLP), a Catholic girls school in San Diego. OLP cheerleaders cheer for their school, as the Pilots, and for St. Augustine, a Catholic boys school. In the movie, real OLP cheerleaders appear at the regionals and nationals, in their Saints cheer uniforms. In the regionals, they are after the Broncos, praying. At the nationals, they are sitting next to the Clovers as the winners are announced.
In the scene where the Clovers are writing someone to ask for money for the competition, the woman they are writing to is named Pauletta Patterson. This is the same legal name of Gabrielle Union's character Mary Jane Paul on Being Mary Jane.
Eliza Dushku and Clare Kramer (Missy and Courtney) were both on the T.V. series Buffy the Vampire Slayer at one point. Eliza was Faith, a second vampire slayer gone bad girl in season three. Clare was the god Glory who takes Buffy's sister to open a portal to hell. Nicole Bilderback (Whitney) also cameoed in a couple of episodes in season three as a Cordette.
In this film Lindsay Sloane plays a bitchy head cheerleader who picks on the junior members of the team. In 'Sabrina the Teenage Witch' she played the junior member picked on by the bitchy head cheerleader.
When Missy hands in her form before auditioning for the team, the section for her name only has her first name on it, with no last name. Also, her address, written as "7762 Winnocks Neck Rd," could only be located in Scarborough, Maine. Missy said she's originally from Los Angeles, so either she moved from Maine very recently, and used her old address, or the movie made up an address to pretend it's where she moved to.
Despite playing brother and sister Cliff and Missy Pantone and are both high school students of the same age in this movie that isn't in reality. in fact Jesse Bradford who plays Cliff is actually 1 year and 7 months older than Eliza Dushku who plays his sister Missy.
In the scene where Missy auditions for the team, she holds up her application. Only her name and street address are visible. The address reads 7762 Winnocks Neck Rd. This is a combination of the address of the actual house used as the filming location for Missy's house (7762 Starlight Dr.) and the street on which prop master Brenton Lane used to live in Scarborough, ME (Winnocks Neck Rd.).

According to the National Federation Interscholastic Spirit Association, many of the stunts the teams perform in the national competition, including fly-overs, basket-tosses with head-over-heels rotation, and stunts more than two bodies high, are illegal at the high school level.
A clip from Blaque's song "As If," which was recorded for the movie soundtrack, is included in the medley used by the Toros for their routine at Nationals. The three members of the singing group star, along with Gabrielle Union, as cheerleaders on the Toros' rival squad, the Clovers.
