My job changes very little because I've found that the more you try to be funny, the less funny you become.

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.

I love doing 'Castle.' We pump out 24 episodes in 10 months, and we work long hours. We do lots and lots of takes, and everyone there is a talent machine. It is a taxing endeavour to say the least, but when you get into a groove, it doesn't matter if you're tired, it doesn't matter if you're sick. You can do it.

'Desperate Housewives' is an ensemble cast, where I played a tertiary character. I made a lot of great friends, but that show didn't keep me very busy.

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.
