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.

It's so great in Hollywood now. You have people past 40 sitting and talking about serious stuff, writing and making movies and TV, but there's laser pistols and superheroes and alien monsters involved. It's viable and mainstream.

I love what I do. And why not be nice? I mean, I've seen people who work and they're apparently not enjoying it, and they're making sure everybody knows it.

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

You know, Castle, like anyone else, is a human being first. If you take a human being - especially a vain one like 'Castle' -and you bring in a gorgeous woman and have sparks fly, who can help themselves? What are you gonna do? Sparks happen!

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