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.

The nature of the beast is, art needs finance. That's how this industry works.

Somebody told me long ago that in acting, it's okay to steal, just steal from the best.

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.

There's comedy even in tragedy. There's comedy in life. And in 'Castle', we go for that comedy.

I'm constantly pitching one episode where we see life through Castle's eyes. I think Castle's just a little off as far as his perception goes. A very, very clever man, but I want to see the world as Castle sees it - kind of a rose-colored glasses, all the women find him irresistible, all the guys find him super cool and do whatever he says.

I am one of the lucky few who is successful in their career, and I'm really enjoying myself.
