Whenever I've messed around with radio-controlled things, there's always been a part of me that's thought, I wonder if there might actually be a little guy piloting these vehicles.

There is something beautiful in the mundane if you take enough microscope to it and focus in on something that seems innocuous to begin with.

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].

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.

When I was 15 I lost a tooth and had an implant put in. Cut to 20 years later, I'm doing this part [Andy Bernard] and the script calls for my character to lose a tooth.

I think the culture of Civil War re-enacting is also incredibly fascinating.

The scene [in The Hangover] where the tiger actually pops up behind us, that's actually a Jim Henson tiger puppet. The Jim Henson Company actually supplied that tiger. And it's really cool. Its entire face moves. It has like all these little motors in its eyebrows and cheeks and mouth. It was amazing.
