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.

You're only as good as your body of work, and everybody has issues, whether it's Steven Spielberg or Martin Scorsese. I'm not comparing myself to those guys, but you learn more from the misses than the hits.

I was taught that you didn't want to be part of the group - that it was better to do your own thing.

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

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

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.

You're never nice to your friends. You're nice to people you don't like!
