You can do crap work in a big movie, and it does good things. You can do great work in a movie no one sees, it does nothing. That's the way it goes.

I still think Brooke Shields is aces. She's really smart, interesting, doesn't feel that her time is more valuable than anyone else's. Really hardworking. And I knew that if she was the star of the show, it's going to be a good experience. And it was.

We tried the first evening to go down Division Street and Rush Street, but we couldn't get in anywhere because they didn't like [ Emilio Estevez] sneakers and they didn't like my boots. This was 1983 or '84, so it was ridiculous. We ended up at a jazz club, where you go downstairs and there's a very cool place.

It's more like the inner workings of John Bender. He feels like he's been given a short shrift, he's not been provided the opportunities that maybe these other kids have. So he feels like he begins in a hole. And instead of trying to raise himself up, he wants to bring all of them down. That's a dynamic that's pretty universal. And so that was the real foothold on that. It wasn't like, "Oh, my high school experience is like John Bender's [in St. Elmo's Fire]."

I don't know if it matters what country you're from, size of the city you're from, urban or rural, there are people that are hurting each other everywhere.

Remember to be as smart as you are.

We worked six days a week [on the The Breakfast Club], so you have one day off. So on that Saturday night, it's not like we could all go out and have a drink because Molly [Ringwald ] and Michael [Hall] weren't old enough. And Ally [Sheedy] pretty much kept to herself. So Emilio and I, every Saturday night, would go into Chicago because we were shooting outside of Chicago in Des Plaines. It's so funny, because even though we might be adversaries in the film, we certainly weren't off-camera. He's a very funny guy.
