Continuity mistake: During the film "Left foot, Long foot" when he's being interviewed for Inside Chappelle's Show Studio , you can see a bit of blood on the top right of his forehead after he gets up after slipping on the skateboard. In one of the following shots when he is looking around at the crowd applauding him you can see the blood is now down by his nose. The next shot it back up the top of his forehead and the following shot its even further down his nose than before.
Revealing mistake: During the dinner scene where Dave is thinking about Arsenio Hall eating cheese, Arsenio starts complaining about how good the cheese is. After punching one guy, he goes up to another and slaps him in the face. When he slaps him you can see he misses the guy's face by a good inch or so.
