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.

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'm sure I cause just as much consternation for editors as any other actor, it definitely makes me feel more comfortable understanding how and why all the different camera setups exist.

I'm a very jaded and cynical person.

The improv stuff, that's always surprising so a lot of times that's really funny.

When you're playing a fictional character reacting to the real world, it's incredibly difficult and confusing and kind of messes with your values a bit.

A lot of kind of like the way that Andy [Bernard] talks, you know, the writers pick up on those things - little moments that I inject and then they start to write it in later. It's hard to say if a whole storyline is spun out of an improv. I feel like it has happened on The Office, I just can't think of it.
