There's comedy even in tragedy. There's comedy in life. And in 'Castle', we go for that comedy.

I have a trophy case that contains all the action figures ever made of me. It also has items I've stolen from my movies, like three guns and holsters from 'Serenity'.

I consider 'Dr. Horrible' a tremendous success. The fact that it won an Emmy I just think lends validity to what we were doing and the point we were trying to make: taking the power into someone else's hands and changing the world.

I realized, dumb people don't know they're dumb. When people try to make me laugh and they try to be funny, that's when they lose me. I find a lot of comedy in honesty.

I'm constantly pitching one episode where we see life through Castle's eyes. I think Castle's just a little off as far as his perception goes. A very, very clever man, but I want to see the world as Castle sees it - kind of a rose-colored glasses, all the women find him irresistible, all the guys find him super cool and do whatever he says.

My first Comic-Con was when I first met Joss Whedon: He introduced me to that world and I'd never been to a convention before that. He and a bunch of the 'Buffy' and 'Angel' writers were all going down in a big van and he invited me along.

When I go to a sci-fi convention, oh God, it's the closest thing to being a rock star I will ever know in this life. I want to be a rock star, don't you? It's a good thing to be, a rock star.
