Castle is a guy living in a fantasy world. He's in his imagination, writing these stories of murder.

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.

My worst day is still a really good day. I complain, but I catch myself and count my blessings. I am truly blessed.

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'.

My dinner spot is usually in front of the TV. I'll grill a steak and whip up a salad and watch 'Hoarders.' I love it because a) I'm kind of voyeuristic, and b) every time I see an episode, I go to the one room where all my unpacked boxes wound up, and I throw out a box of stuff.

I like doing things where I can get dirty, work with my hands, and use power tools. Last weekend, I did some grouting.
