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: 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: 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.
