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.'

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

I find I like to work with a lot of the same actors, because I find that there's sort of shorthand there, and there is this unspoken trust, both ways. They trust me and I trust them. And I know what I'm going to get from them, to an extent. It's just fun, kind of creating this little family.

I think that 'Hangover II' is as funny as 'The Hangover I,' honest to God, but I think that it's a little bit darker, and the stakes are a little bit higher.

I take it very seriously, music. I think it's one of the tools that a director has with which to kind of paint. The right music can sometimes do five pages of scripted dialogue.

There's such an awkwardness to most heterosexual male relationships. You see women who are friends, and they kiss each other good-bye, and they're just so much warmer with each other. But there's this thing with guys where, even between best friends, there's a standoffishness.

My dog's a gentleman.
