Trivia: Although in real life Principal Joe Clark improved the discipline problems at Eastside High School, he did not, contrary to what the film has you believe, improve the academics in any meaningful way.

One of these years in particular, under Clark's tenure, Eastside High's passage rate was as low as 24.1%.

Trivia: A great deal of the film was actually shot in Japan, and it was reportedly very difficult on the cast and crew.
