I've had a long line of failed television programs, pilots that were never picked up, series that didn't go very long. I've learned that there's really nothing you can do. If it's not in my control, I try not to worry about it.

I'm actually reading 'World War Z' again! It's incredibly realistic and it's written as an oral history through interviews with different characters. Max Brooks wrote this book in so many different voices. There are about forty or so. It's incredible. When I finish 'World War Z' I'm going to go back and start again on the 'Game of Thrones' series.

You have a dramatic portion of your television program and you treat it dramatically, and then you have a comedic portion of your program, and you treat it differently. Why do you change who are between the two pieces? You're the same person. Just go.

I think about my own daily choices every day in terms of how to find happiness.

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.

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.
