When you're looking for stories or movies usually the great stories are about people in their 30s or 40s because they've lived more life and they're usually accomplishing more incredible things. But when there's an interesting story about someone that's your age, you immediately - especially when you're younger - are like, "Wow that's crazy! There's not very many of these."

The comedy really comes from how badly you want these characters to succeed and with a comedy that's often hard.

Sometimes what happens I think is that actors finish a movie and they go, oh my god, I'm never going to work again, even big huge actors, and so they'll take something thinking that something else will never come along. But for me, I freak out - because I'm a bit of a workaholic - the second I finish a movie going oh my god, what am I going to do, but I can start writing the next day so it doesn't force me to make a bad choice acting-wise.

I've learned through experience of playing different characters, some of whom were jerks, that when you play a character who is pretentious or obnoxious, in any way, it's important to knock them down a peg.

I learn a lot from every director that I work with. I sit on set and watch them, every one.

People who are just in a restaurant that you would never know are international arms dealers is kind of interesting, they're at the table next to you and you have no idea, you never know what everyone's up to.

I think our culture has gotten so skewed. People assume that because you're an actor you want to write a book to exploit your celebrity, but my celebrity is only a byproduct of me making movies. I have no intention of being a celebrity.
