It's so great in Hollywood now. You have people past 40 sitting and talking about serious stuff, writing and making movies and TV, but there's laser pistols and superheroes and alien monsters involved. It's viable and mainstream.

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

'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.

Working on Drive, a lot of fun. This is Tim Minear whom I've worked with before on Firefly of course. He called me up and said I've got a part for you that you will love and I love Tim's writing. I love his stories. I love his characters, his dialogue. He has a knack for reveals and he has a knack for moments.

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 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.

You know, I endeavor to be more like my older brother. He's very magnetic. He's actually very much like 'Castle' in that people are attracted to him, and just want to be near him. You want to know where my brother is in a crowded room? He's the guy with the crowd around him.
