Audio problem: When Lane plays his sax at the Pig Burger for Monique, the sound was obviously dubbed from a synthesizer. (01:20:20)
Continuity mistake: In the scene where Monique is introduced to Ricky at in the movie you see Ricky remove the red cap of his nasal spray and drops it as he goes to spray it in his nose. When the Camera zooms in on the next shot of him snorting nasal spray you can see him drop the red cap again. (00:08:40)
Continuity mistake: When the kid shows up asking for 2 dollars he has a hat on. A second later miraculously he whips out a comb and starts combing his hair.
Other mistake: After Lane Meyer gets beaten up by the basketball team he goes out to his car and it has a flat tire. Not only does he not notice, but he gets in the car and drives away normally. (00:32:18)
Suggested correction: How is this a mistake? Lane just got raked over by an entire basketball team - he is exhausted, humiliated, injured, and wants to get out of the area immediately so he would not care his car has a flat tire.
