Continuity mistake: First, we see Mr. Renaldi put both arms above his head while lying on the bed. Then in the next shot, he has them both down. His arm changes continue for the next two shots. (00:34:10)
Continuity mistake: In the scene where the boys are fighting in front of the "Avalanche" ride which Medusa has sped up, Amanda hits the emergency stop button and accidently stops the ride upside down. In the very next shot it shows one of the boys fighting in front of the ride, and the ride is now moving.
Continuity mistake: At the beginning of the song "Old Deuteronomy" watch the positions of Jo Gibb and Drew Varley flip flop in the background between long and close shots. Soon afterward, Cassandra slides down to the stage in a closeup and immediately slides down again in the long shot (while singing different lyrics). Apparently the long and close shots were often filmed in different takes and the choreography and positioning of actors were sometimes not matched very well.
Continuity mistake: While standing in the water, the guys' bong jumps from hand to hand between the three of them without being passed.
Continuity mistake: When the movie first begins, Jan is talking to radio talk show host Howie Carr, if you look really carefully at one of the shots, Howie has a pen in his hand that he is holding steady. In the next shot, he is twirling the pen in his hand. The next shot shows the pen steady again.
Continuity mistake: When Henry Bell is ready to jump off Tower Bridge he is soaking wet. He hears a woman crying help, gets down to investigate and is much drier. (00:04:00)
Continuity mistake: At the beginning of the film, Bill is shown coughing up the white gloves that had been stuffed completely in his mouth. However, later in the film, Cobb does not completely stuff the gloves in Bill's mouth.
Continuity mistake: When Karin takes the gun up to her face to shoot herself, she takes it up to her left ear, but in the next shot the gun is at her right ear.
Continuity mistake: When Elwood, Mac, and Buster arrive at the Monster Truck show to sing. We see Mac get out of the car. If you look carefully in the background you can see Elwood already going up to the stage. Then the camera switched to show Elwood getting out of the car.
Continuity mistake: As Buddy and the kid pull away in the car for the first time, Buddy is staring out the right side of the car. The shot cuts to a different angle and he's looking more toward the left.
Continuity mistake: In the scene where Richie is running away from the gaurds he dives over the platform and knocks over the statue with his foot, but when the other gaurds go to jump over it, the statue reapears.
Continuity mistake: Dwayne puts on lipstick, then prepares to put a plastic bag over his victims head. The lipstick disappears just as he is putting the bag over her head.

Continuity mistake: In the marching band scene they all have long shadows, and then suddenly they have no shadows at all.
Continuity mistake: When Sammy is singing, Frank comes over and leans into the mic to sign with him. The camera angle changes and his arm is now around Sammy's shoulder.
Continuity mistake: When the girl goes to the bathroom she drops her cigarette into the sink, you see it bounce and go to drop into the drain, but in the next shot of it is lying across the drain.
Continuity mistake: Birdie and Justin are dancing to a song and when it ends the band announces, "We are going to take a short break and leave you with some fine tunes on the jukebox." The song "To make you feel my love" starts, but as they are dancing you can still see the band playing and someone singing.
Continuity mistake: When Sammie wakes up alone in bed, she can see a rapidly moving shadow inside the bathroom. After she sneaks outside the house around to the window, she looks in and we see Sam in the bathtub, masturbating to magazine centerfolds. The problem is that in this second shot, Sam is very far from the door and there is no shadow visible inside the bathroom. In fact, there is not even a light source on the other side of the door from him. Sammie therefore should not have seen a shadow from inside the bedroom.
Continuity mistake: In the scene where Fantine is dying, she asks Jean Valjean to give a necklace to Cosette. There is a closeup of Fantine's head and neck and Valjean's hands enter the shot and begin to remove the necklace. A moment later she begins to cough and there is a cut to a two-shot of the pair from a few feet away. Valjean's hands are nowhere near her neck in the second shot.
Continuity mistake: After the photo shoot on the beach the characters are passing around a jug of wine that is almost empty in one shot, but each shot after that it is closer to full.
