Continuity mistake: When Beth and Jam hit heads to pick up his drumstick, she is holding the stick in her right hand. Then next scene, she's rubbing her head with her right hand and holding the stick in her left hand. Then they go back to the original scene and she hands him the drumstick with her right hand.
Continuity mistake: When the kid is running from the security guards he crawls under some trucks. But if you look in the background in between the trucks it is raining, but after he gets out from under the last truck it's not raining anymore.
Continuity mistake: The slice of pizza on the disco guys' windshield changes from shot to shot. In the close-ups, there are hunks of cheese and drippy sauce splattered all over with crust, yet, in the wide shots the windshield is cleaner, with just a small triangle of crust.
Continuity mistake: While the four guys are on their way to Detroit, Trip is hanging out of the sunroof. In the next few shots, you can clearly see that the car has no sunroof for Trip to hang out of. [The Volvo does have a sunroof the whole time, it is actually a moonroof with clean lines that are hard to notice.]
Continuity mistake: In the toilet scene one cheerleader pulls her panties down. They slide to her feet, but in the next shot they are a good 15cm up from her ankles. Unless she can make things rise with her mind, that's not supposed to happen. Also when her panties slide down her legs there is a sound of someone lifting a toilet seat, but she is already sitting down. (00:18:00)
Continuity mistake: The brake pedal on the Trans Am is first shown with chrome trim around it when the driver stomps on the brake to cut off the Volvo. When the rock is put on the gas pedal to send it into the ditch, the brake pedal is seen to have no chrome trim.
