When we were not shooting [The Hangover] we were sleeping, so pretty much every waking moment we spent together. And, you know, Bradley [Cooper], Zach [Galifianakis] and I were acquaintances before the movie started but we became good friends very quickly and spent so much time together that it was just inevitable we were either going to really hate each other or really like each other. Thank god it turned out to be the latter.

You take a vacation to a place like Thailand and you're ready for the excitement of something new and foreign. But when you're working 14-hour days, all you want is something familiar to ground you. And there's just nothing there.

The piano song that I do in the movie [The Hangover], it's a great example, that was never - that wasn't in the script.

It's a very collaborative environment [making The Office]. We always do takes of how it's scripted, but then we also mix it up a lot too. And it's kind of a crapshoot, you never know which one... I mean a lot of time improvisation doesn't go anywhere and it's not good at all but, so what was written is often times better.

What's cool is that in the story of the movie [The Hangover] our characters are also really kind of getting to know each other and bonding over the course of the movie. And I think you're seeing a real, a literal sort of friendship growing both in us as actors and on screen as characters.

Todd [Phillips] doesn't care. That's part of his genius as a director, he will say anything to anybody.

There are certain relationships in our lives that implode, and it can feel really inexplicable and terrifying. You don't know why, and sometimes relationships end for reasons that one person keeps from the other person, and it's just totally unclear, and it just goes south and it's heartbreaking.
