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.

What I know of Steve Trevor is everything that I learned from 'Wonder Woman,' the television series with Lynda Carter. And I don't remember much. I do remember his uniform, though.

I told myself a while back, 'Love what you do, but don't fall in love with what you do.' That way you won't be brokenhearted if ever it gets canceled five episodes in - which has happened to me.

It's a thrill to be a fan amongst fans.

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

I don't spend a lot of time online. My mother's really good at picking out if she sees a really great review, and she'll forward it to me. She's like my little Internet filter. It's always nice to see something going up; if I want to find something on Nathan Fillion, I do know where to look, but I've got a nice little delivery system in my mom.

Somebody once said that you can never act and be another person; you're only acting facets of yourself. I think there's a lot of truth in that.
