Corrected entry: In the scene for the cheerleading fund-raiser car wash, Cliff comes up with his car and Missy has Torrance come over so Cliff can "check out her rack". Cliff says, "I begged my mom for a brother". This is not possible, as he is younger than Missy.
Correction: Cliff is actually older than Missy, not younger.
Corrected entry: At one point in the film, Missy says, "State Regionals, here we come," but any high school athlete, particularly a cheerleader, would know that a Regional Competition takes place within a state, and those placing highest at Regionals would then move on to the State Competition.
Correction: Character error not film error.
Correction: Missy wasn't always a cheerleader, she was a gymnast. She could have easily been confused about the competitions simply because it was new to her.
Correction: They are actually twins.
