Continuity mistake: At the end of the very last drum scene, all the A&T snare drummers drop their sticks onto the other drummers' snares. They all drop them, most the sticks fall to the ground, the shot changes and you see all the sticks still bouncing on the drum, and the snare drummer closest to the camera is just dropping his stick.

Continuity mistake: In the scene in the cafeteria where Ernest is pigging out, Ernest is shown eating half a burger, then the shot changes to his friends watching him. When the scene changes back to Ernest he's shown taking a bite out of a whole new burger, but only a few seconds went by. When did he have time to get a new burger?
Diedre: Hey Devon, ya know, if you keep messing up, Ernest actually might get a chest.
Ernest: And Diedre might get strong enough to pick up a hot comb.
Trivia: The main drummer for Morris Brown at the end of the movie during the tie breaker is the actual drummer used for close up shots of Devin's hands when he has to drum.
