I want my job to include a little adventure, a little more of a heightened reality than what I'm actually living. And 'Castle' has that. He gets this opportunity to tail these homicide detectives, and he's driven by that. He's a little immature, but he's obviously loving life.

I'm not a big prop actor.

I think it's a dance that people want to see. It's a chemistry that people want to see. In the same way that people don't want to see a perfect hero with no flaws who can handle anything, people don't want to see a perfect relationship. There's nothing interesting about that. People want to see you fail.

I like making sci-fi movies because I like watching sci-fi movies. I like watching horror. I like being in a horror movie. I'm a fan. My perspective's a little different just because I get to participate as well as spectate.

I'm comfortable only when there's a mutual attraction. That's what anyone wants. If I find out she's not attracted to me, it brings down my level of attraction to her. If I'm interested and find out she's not, I tend to cool off.

I would cancel dialysis to be in the [hopefully upcoming Firefly] movie.

You have a dramatic portion of your television program and you treat it dramatically, and then you have a comedic portion of your program, and you treat it differently. Why do you change who are between the two pieces? You're the same person. Just go.
