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 never had a ton of male friends and it's always been something that's really interesting to me, what brings guys together? The bonding. 'Old School' is a good example of that. And even 'Starsky' and even 'Road Trip.'
When I was in NYU Film School I drove a taxi in New York for two years, I felt like I owned my own business with that little taxi.
