Continuity mistake: Leslie Ash's dark shoes change to white trainers halfway through the Riot Scene.
Continuity mistake: When Steve Martin is on the spinning carnival ride, the positions on either side of him are empty, and then in the next shot both spots are occupied.
Continuity mistake: When Bette Midler is in the phone booth toward the end of the film, calling home and crying, she empties out her purse on the little shelf. A huge roll of money is prominently placed amongst the coins and other items. From shot to shot it can be seen sitting upright and then on its side.
Continuity mistake: In the scene where one of the hall monitors is folding the principal's note into a paper airplane, watch his cigarette. It goes from being in his mouth, to being in his hand and back without him moving it.
Continuity mistake: When Linda Blair deliberately knocks a plate of desserts into one of her suitor's lap, the tray hits him directly in the crotch and the camera shows this. Then there is a cut to Linda Blair's face and then a cut back to the boys clothing and the scene now shows the desserts all over his suit from the shoulders down.
