In all my characters, I try to find an iota of myself, and in Castle, I found a lot. He gets away with a lot, so that's fun.

I kind of found a niche for myself after 'Firefly'. I found something that I enjoyed doing and that I did well, but as far as how I seek out a part, it's always different. It's always something that lights you on fire when you read it. It might be just one scene, it might be one line that defines the character for you.

I thought what would be really just choice for a revamp and a reboot is 'The Greatest American Hero.' I think I'd be just that kind of perfect not prepared for this kind of thing, but thrust into circumstances he's not prepared for... that's another niche of mine. Unpreparedness. Not knowing what to do. I'm good at being that guy.

There are people who have energy that say don't come near me, don't get too close. There's people like Adrienne Shelley who have the energy of come over here and give me a hug and if you're around me you're going to be happy about it.

It's a trap I've fallen into earlier in my career - trying to be liked. Don't do it. When I watch TV and I see someone trying to make me like them, acting cute or quirky or goofy, I'm not impressed. Don't act like America's watching you. Just latch onto your character. Characters are flawed. Be unlikeable. Be flawed. Be a person.

With scheduling and the way projects come up, I take the first thing that interests me and that moves me. If it's going to be fun, if I'm going to have a good time, and I'm going to enjoy the people I'm with, then that's a good enough reason to do it.

I don't have 4 or 5 projects in front of me and an offer on every one saying 'what one would you like to do?' Things come along one at a time.
