What's nice about writing and making films is that being able to see a film from the outside - from the inception through production and then completion - just informs what you're doing when you're an actor. And when you're an actor, it informs the decisions you make when you're making a film. It's using two different sides of your personality.

I think you should identify with your character, but plenty of people like themselves and hate themselves. You just have to find out what's truthful for the person you're playing. When people talk about that, I think what they're saying is that as an actor, as Peter, you don't want to make a judgment that comes from your worldview about the character. Your judgments should be coming from the place of the character, and within that space, sure, you could love or hate yourself or whatever you think is most appropriate.

I did my friend's film - this guy Harrison Atkins who's a great filmmaker. He just makes movies with all his friends, and I think that's all what we're striving for - to feel like we're among friends and people who care about each other. I'd like to think that good work comes from that - from a sort of loving and friendly environment.

You would almost think it would be the opposite, but making a film sort of made me freer in my acting.

When you're watching yourself work, you're not really an audience member for yourself. Even being confronted by your own image can be jarring sometimes. The experience of making a movie or a television show is this really full one, and sometimes you see it and even if it's a great piece of work, it's not the experience - i t's almost sad because it reminds you of something that isn't anymore.

It's always nice to have a large role, but if it's a great small part, those can be so much fun. Size is less important than quality, always.

I was born in the West Village in New York, and then when I was about four my family moved to what they joke is the suburbs, the Upper West Side. I lived there for most of my childhood.
