You want to put out a TV show? If you have the money to do it on your own, by yourself, and you have a TV network, you can do it by yourself. But the nature of the beast is, art needs finance. That's how this industry works. So until the Internet becomes our source of entertainment - and watch it, I believe it will - this is how things go.

I enjoy the art, and I enjoy drawing. I think my printing to this day looks like the printing right out of a comic book.

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'.

Improv as an actor makes you present in the moment. You listen, you're attentive. You're not acting so much as reacting, which is what you're doing in life all the time.

MEN WALK ON THE MOON. To me, this speaks of a time when America wasn't just about the almighty buck. The Russians had put up Sputnik, and the U.S. would not be outdone. I admire that about the American spirit. There's only one spot in history for the first ever of anything.

Castle isn't really affected emotionally by murder. He's thrilled about, 'Oh, my God, I wonder how this happened?'

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.
