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 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.
I make decisions to do movies based on the cast. I'd just been working with Zach Galifianakis on 'The Hangover', and I was thinking, I've got to find something to do with this guy immediately.
