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 like - there's a better word for it, but I like the danger that a comic brings to a role. It has a feeling, even though everything's scripted and everything's planned what you're going to do. When I see Will Ferrell or Sacha Baron Cohen, there's a feeling that anything could happen.

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

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 think people like comedies and I think concept driven comedies seem to be working when it's a clear concept and you deliver funny stuff.

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.
