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 have done much more dramatic work than comedic work, but I think comedy is harder than drama in a way. I think it's one of those things that's constantly discussed - people who do comedy think it's harder, people who do drama think it's harder. Usually drama is the one that gets this highbrow respect.

If you're in something and you feel like it's not going well, what can you do about that? It's out of your hands. No matter what you do, you're not going to fix that as an actor.

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.

I was really able to confirm something that I knew on some level before I'd made a film. The best actors know how to really relax. Because in film, a lot of the decisions are made in the editing room, so when you're trying to guide your performance too much - always it's a push and pull because you can't be too relaxed. Too relaxed and it's like, "What are you doing?" Too tense and it's not good either.

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.
