I'll tell you what I really enjoy. We all go to the movies, we all watch television, we know what they're about, how they work. When the main character is a cop or a spy, it's very exciting, but I also very much enjoy when the main characters are nobodies - a trucker.

The trick is, when you grow up, find work that feels like play.

I love hiking in the hills not far from my house. I'm invested in my hikes. Sometimes kids go up there and spray-paint over the signs; I've found a biodegradable paint cleaner, and I'll scrub the signs so they're nice and clean.

I like to say there's certain things you can't take back: One of them is 'I love you,' and one of them is bullets.

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.

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

I would cancel dialysis to be in the [hopefully upcoming Firefly] movie.
