I have a cat. I'm not a cat-person, but she came with the house that I'm renting. I don't know how many hundreds of dollars worth of bump removals, teeth removals, cleanings and vet fees I've been through. But of course I love her and she's worth it.

When people embrace character, there's latzie. It's the stuffing of a scene that's not written. It's not in the stage direction and it's not in the words. When people embrace character, it informs their living, breathing moments in a scene so well.

I tell you, 'Firefly'? Best job I ever had. Heartbroken when it was canceled, but had it not been canceled, I never would have gotten 'Serenity'. I think 'Serenity' is the most incredible thing I've ever been able to actually get my hands on and do. I can't even tell you how much love I have for that project.

'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.

Whatever our bedtime was as kids, we could stay up an extra half hour if we were reading. My parents didn't care as long as I was under the spell of a Stephen King or a Douglas Adams. Now I read in bed. I read at work. I read standing in line. It's like, 'Hello, my name is Nathan and I am a reader.'

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.

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'.
