I really just like acting. I'm not always aware of what is hip and what is popular and what is zeitgeist.

It's a roll of the dice in the movie business. I mean, every single movie is a roll of the dice. Any movie on paper could look like it's going to be fantastic. You know what I mean?

I've done movies that I've been advised not to do. 'Dog Soldiers,' the movie I did 11 years ago now, I remember my agent at the time was like, 'You shouldn't do that. It's a weird film about werewolves,' and it became a cult hit.

In the late-'80s, there was a big push to make American football big in Scotland. The Super Bowl was on TV, but it didn't really catch on. When I was a kid, though, I became a big Miami Dolphins fan. I don't really know why - I just liked the logo, I guess. I didn't really know what was going on.

Grey's' is just a machine. I wasn't really prepared for the epic nature of how popular the show is.

I'm always very excited by something that's a curveball or from left field.

I suppose I am a frustrated musician so I annoy my family by playing guitar in the house. I used to be into acoustic stuff but my son Joseph is learning drums, so now I have an electric guitar and we play Metallica. We have an amp and a PA in the garage with his drum kit.
