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)
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)
Revealing mistake: When the dark-haired kid's hand gets cut off, no blood is ever seen spurting from the stump. (00:07:25)
Revealing mistake: When Bruce is hijacking the old woman's car, what he is pulling out of the driver's seat is obviously a stiff, non-moving dummy. (00:57:35)
Visible crew/equipment: When Bruce returns to his trailer after running away, you can see the entire film crew reflected in the shiny side of the trailer. (01:01:05)
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)
