When you work on a movie or a TV show, you're a family, so if something that's a two-minute thing in the movie is causing a rift in the family, you also have to think about at what point do you fight this, and at what point is this rift worth having in this very small, very tight group of people who are just there to make something great and funny.

I make decisions to do movies based on the cast. I'd just been working with Zach Galifianakis on 'The Hangover', and I was thinking, I've got to find something to do with this guy immediately.

I'm not worried about young people seeing an opportunity and taking advantage of it.

Reality television hasn't killed documentaries, because there are so many great documentaries still being made, but it certainly has changed the landscape.

There's a darkness under 'The Hangover' because ultimately there's a missing person and it's not really that funny. There's a sort of darkness under it that I love, and still people are laughing as hard if not harder than they did in 'Old School.'

I feel like movies when they work they'll find an audience.
