Other mistake: When Joe Clark first comes to Eastside High as principal, he takes it upon himself to confront the staff. At one point, as he begins to turn his back, watch his lips. His mouth does not match the words being spoken.
Other mistake: When Mrs. Barrett spoke out at the parent's meeting after the expulsion of the bad kids, she shouted out 'he insulted the black football coach'. Joe Clark insulted him at a staff meeting, and she wasn't there. How could she have possibly known about it?
Suggested correction: Because Clark demoted a black coach and replaced him with a white coach. Some black people would consider that an insult.
