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.

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.

I think comedy directors tend to feel a need to justify the bad behavior, and I just never think that. I like bad behavior, I've always liked bad behavior, I'm a fan of bad behavior, and I don't think you have to justify bad behavior.

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!

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.

Music is just one of the tools a director has with which to paint and I think it's one of the most effective.

I think a lot of American comedies tend to apologize for their bad behavior in the last 10 minutes of the movie.

I just thinks it's interesting what it takes an actor to find their characters through the wardrobe, or the hair, or the way a character walks.

How many days do you have that are just purely dramatic? How many days do you have that are just purely comedic? It's usually a combination and I think that's what real life feels like.
