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

I kind of fell backwards into acting. I was studying to be a high school teacher. I look now and I understand completely, or actually barely, how much work it is to be a teacher. It's an incredible amount of work.

I'm the biggest geek of all. Adventure, fantasy, comic books - I can't get enough.

I've always fantasized about being on TV. And I was. Then I fantasized about being in the movies. What could be better than captain of a space ship? I get to ride horses, shoot guns, have adventures.

I remember when TiVO first came out I was all about TiVo. I came home and that thing was frozen, and I thought 'This is awful. This is the end of the world'. Then I unplugged it, and I plugged it back in, and still frozen. It was paralyzing. I called them. They said, 'Just unplug it longer.' Fixed. But it also taught me I'm an addict.

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.

It's hard to shake a stick at success.
