Breakfast Club - I work in a high school, and I can tell you that this is the most honest and relevant high school movie ever made. If you don't believe it, you are either fooling yourself on purpose, or you have forgotten what it is like to be a teen!
Directed by Barry Levinson. With Dustin Hoffman, Tom Cruise, Valeria Golino, Gerald R. Molen. Selfish yuppie Charlie Babbitt's father left a fortune to his savant brother Raymond and a pittance to Charlie; they travel cross-country.
