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 set the tone on the set that you want to see in the film.

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.

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

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.'

Every weekend in history has worked for movies if the movie connects.

I just love the look of film. But I have nothing against HD.
