Audio problem: In the scene where Jack Brown (Richard Pryor) is talking to Eric about "Earning a friend" there is a problem with the lip-sync when the camera changes to an overshoulder of Richard. His mouth is moving but the spoken text is different. This occurs repeatedly during that scene.

Continuity mistake: In the scene at the fund raising party where Jack and Master Bates are messing up the party, the Grand Wizard of the KKK is pushed into a bowl of chocolate pudding. The amount of pudding on his face constantly changes in subsequent shots from completely covered to partially to completely to partially to finally completely covered.
Continuity mistake: When Jack Brown gets in the Wonder Wheel, he did not hook his feet into the foot straps, he only steps on the foot straps. When he is rolling in the Wonder Wheel his feet are supported by the Wonder Wheel as if strapped in properly. Since he was not strapped in his legs should have fallen down when he was upside down.
