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.

It's a trap I've fallen into earlier in my career - trying to be liked. Don't do it. When I watch TV and I see someone trying to make me like them, acting cute or quirky or goofy, I'm not impressed. Don't act like America's watching you. Just latch onto your character. Characters are flawed. Be unlikeable. Be flawed. Be a person.

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 job changes very little because I've found that the more you try to be funny, the less funny you become.

Oh, boy. I'm still in touch with about 90 percent of my exes. They would describe me as being unlucky in love.

I live in Los Angeles and I like to do a lot of hiking. I live a very relaxed life.

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.
