All my movies, as I get the ability to do it, they tend to go a little darker, a little darker.

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 think comedy directors tend to feel a need to justify the bad behavior, and I just never think that. I like bad behavior, I've always liked bad behavior, I'm a fan of bad behavior, and I don't think you have to justify bad behavior.

I just love the look of film. But I have nothing against HD.

My movies before tend to be just funny. But it wasn't a conscious thing I was looking for at all.

Comedy is so subjective. You could be in a room with 400 people laughing at a joke and you could just not think it's funny. You're just sitting there like, 'Am I in the twilight zone? Why is everyone laughing?' It's such a personal thing. People have such a personal visceral response to comedy.

I never had a ton of male friends and it's always been something that's really interesting to me, what brings guys together? The bonding. 'Old School' is a good example of that. And even 'Starsky' and even 'Road Trip.'
