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.

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.

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

I was raised by my mom. She taught me how to be a gentleman; nobody in the movies taught me. I think people are raised by their parents. If you're raised by movies, it's a whole other set of problems. I don't think it's as simple as me saying movies are meant to entertain, but I certainly don't feel moral responsibility in putting this out in the world and being like, "OK, this is going to affect how guys make decisions because they see some of my films or whatever." I just don't.

You know, if I started worrying about what the critics think, I'd never make another comedy. You couldn't pick a less funny group than critics - you couldn't find a more bitter group of people!

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.'

Not every movie has to serve as every audience member's need for completion.
