I told myself a while back, 'Love what you do, but don't fall in love with what you do.' That way you won't be brokenhearted if ever it gets canceled five episodes in - which has happened to me.

The truth is I'm a dork. I collected comics. I still love cartoons. I'd rather be at home on a Friday night than out at some club… My sense of humor is that of a geek. My likes and dislikes are that of a geek. I've memorized every crappy sci-fi movie there is, but still haven't seen Schindler's List.

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

I've had a long line of failed television programs, pilots that were never picked up, series that didn't go very long. I've learned that there's really nothing you can do. If it's not in my control, I try not to worry about it.

I don't expect anybody to know who I am.

The secret to comedy is not playing the comedy, but actually playing the situation, playing the drama of it.

I love what I do. And why not be nice? I mean, I've seen people who work and they're apparently not enjoying it, and they're making sure everybody knows it.
