We played around and improvised a ton [in The Hangover], and I think it's hard to say at this point what's what. Gosh, I wouldn't even know how to take a stab at it. The script was so good that we really didn't need to improvise very much, but I think we just found a lot of moments on the set. It's really cool when you get onto the set of a movie and you start shooting the scenes and you start to actually incorporate the environment.

I mean they [ Bradley Cooper, Zach Galifianakis] are both just really good guys and also they're both extremely funny in very unique ways. We made each other laugh an awful lot, and that goes a long way. And we also went through some hard times. I mean it was hard to make this movie [The Hangover].

They [Mike Tyson and Todd Phillips] actually struck up a really pretty incredible chemistry, those two, and I think they really trusted each other.

February is a month of months, and there is one special day: Valentine's Day on the 14th. I know it's still a ways off, but I just can't wait. Janice, if you're watching, will you make me the happiest man in the world and get out of my apartment?

I loved the show Lost, in part because the writers were so nimble in how they would take things from previous episodes, that probably weren't created with any intent towards a larger narrative, and they would get woven into narratives in a really elegant and exciting way.

You make adjustments according to the specifics of the character.It's something I feel like a lot of my comedic heroes have always done. It's not even necessarily vulnerability, always, but it's an earnestness, a genuine desire to actually do the right thing, but then still make really misguided, stupid decisions along the way.

There really aren't any deletes [in The Hanover movie]. There's like one or two deleted scenes but they're not important or meaningful scenes.
