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.

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.

I've always noticed a difference between working with a director and working with a writer/director. In how much they're invested and how specific they are.

No one wants to see a person on TV who's super-ultra-cool. That's Superman, that's a thing of the past. Heroes are now flawed, and have terrible tempers, you know? They're real people.

I've got a full plate, yes I do. That iPod that's nice. A phone recorder? Nicely done. All right I'm a bit of a tech geek. I have a subscription to Popular Science and I keep up on all this stuff.

I'm the kind of guy who, I need a watch that tells me what day it is. I need to know it's Friday on my watch. I need to look at it and go, 'Friday today.' Tomorrow I will not know it's Saturday until I look at my watch. My watchband broke, I was crippled. I have no concept of time, I have no concept of dates.

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.
