I listen to a lot of Chicago blues, I suppose. It reminds me of growing up, I guess. But I'm also obsessed by close-harmony groups. Actually, I'm fascinated particularly by brother duos, how they blend together. The Everly Brothers, the Stanley Brothers, The McQuarrys. There's something inherently magical about harmony.

I actually envy actors who have a persona: 'This is the way I am. This is the part I play.' And do it over and over and over. To me, that's a lot easier than trying to reinvent yourself every six months.

Why people pick me for the roles that they do is a bit of a mystery.

I think just getting a movie done is an accomplishment in itself.

That's one of the difficult things of being an actor that I'm still not used to. You have to go, you have to show up at these places where you know nobody, and sometimes with really impressive, high stakes people like Roman Polanski.

Somehow that doesn't feel like a natural human thing to do, to go to those dark places, you have to kind of force yourself to do that. And comedy, it's like you're excited to get there in the morning every day.

I love to improvise, but I always thought "Man, it's like the final frontier for improvisational actors, to really go for something emotional, something that's not just chasing the laugh."
