It's all about escapism. That's essentially what all movies are about. It's a vicarious thrill.

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.

You set the tone on the set that you want to see in the film.

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.

It becomes pretty crystal clear once you watch that first assembly [movie cut] the things that are just grinding it to a halt, so to speak, or slowing it down, or getting in the way, yeah.

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.'

I love confidence in a guy. I don't have it, but there's nothing sexier.
