Continuity mistake: At the beginning of the movie when Flash and the Ebony Sparks are performing, you can see behind Flash, the back-up singer on his right (our left) throw his red sports coat and bow tie on the ground and rips open his shirt. Then when they show a close up of the back-up singers he has it buttoned but is in the process of taking it off. Then when they focus back on Flash, the man's shirt is clearly open, then they go back and he's still trying to open it up and he finally rips it off and goes in the motion of throwing it, but then (less than second) it pans out to show the whole group jump up and do the splits at the end of the song and the man has the shirt on again.
Factual error: Morrison did finish film school in real life. He did not drop out as depicted in the film.
Revealing mistake: Towards the end when Vanilla Ice jumps the motorcycle over Nick's car, you can see the ramp he used through the car's windshield.
Factual error: When Madonna greets her audience for the kick-off night of the Blond Ambition World Tour in Tokyo, we're actually seeing the second show, not the first.
Continuity mistake: In the Fish and Chip van, the guy with the pony tail says, "I'm going to fart." The next few shots have his head alternating in different positions even though there was no time for him to move.
