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.

MEN WALK ON THE MOON. To me, this speaks of a time when America wasn't just about the almighty buck. The Russians had put up Sputnik, and the U.S. would not be outdone. I admire that about the American spirit. There's only one spot in history for the first ever of anything.

When people embrace character, it informs their living, breathing moments in a scene so well.

I want my job to include a little adventure, a little more of a heightened reality than what I'm actually living.

Being in the industry, I've seen many situations where someone will get the call from the network where they say 'You guys have 5 episodes to wrap it up.' Then all your long-term story arcs gotta get wrapped up in five episodes because that's how many episodes you got left. I would hate to see that happen to 'Castle'.

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.

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.
