Continuity mistake: When Bruce gets back to his trailer after realising Guan-Di is for real, he places a cereal box and a milk carton next to each other on the table. When it cuts to a close-up of the answering machine, the milk carton is gone. (01:02:00)
Continuity mistake: In the beginning, Jeff and his friend are having an argument about movies. As Jeff says "Yeah, so what", he is staring ahead, even turning his head slightly away from his friend. When the camera cuts to a wider angle, he is looking directly at his friend. (00:02:35)
Continuity mistake: When Jeff and the dark-haired kid are talking in the car, the little disco ball hanging from the rear-view mirror varies between swinging very gently and swinging with large, rapid movements, without anyone touching it. This is especially noticeable in close-ups, when Jeff is shown, the ball is moving violently, when the camera is on his friend the ball is barely moving. (00:01:50)
