Corrected entry: If you watch the film with English subtitles, then there is a spelling mistake when Enrico is in the van with Wayne. Wayne says "We'll take a peek at it" but peek is spelled peak, meaning the top of something.
Corrected entry: When Zack and Enrico are standing in front of the electric fence, Enrico tricks Zack into looking away, and then runs and jumps onto the train, while Zack sort of runs after him. In that shot, you can see no fence, but when it cuts back to Zack, he's standing right behind the fence again.
Corrected entry: When the two brothers, Blaine & Duane, are chasing the hardware guy who stole their key, Blaine goes onto the car's hood while Duane drives. When he's on the hood, he accidentally tears off the hood ornament. But later in the scene, the hood ornament is attached again.
Corrected entry: When Cuba Gooding is convincing Marty the bus driver to give him his uniform, he only takes his pants, jacket and hat. At a later time right before the Lucy look-a-likes chase him, he has socks which the cab driver took from him and he has a white shirt which again he never took from the bus driver. (01:23:14)
