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

They're truly living in a fantasy world. They claim to represent the public but we're offended by claims they make.

I'm the biggest geek of all. Adventure, fantasy, comic books - I can't get enough.

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 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.

To be matter of fact about the world is to blunder into fantasy -- and dull fantasy at that, as the real world is strange and wonderful.
