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

If a man comes up to me, I'm almost sure he's going to mention Rome, if it's a woman, it'll be 'Grey's Anatomy.'

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.

I was asked to be in the last two 'Harry Potter' films and I couldn't do it because I was busy filming 'Grey's Anatomy.

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.

I live in LA so I worry my kids aren't that connected to Britain, I suppose I don't want them to become American kids. We try to get back three or four times a year. When they go to school they speak with a British-American accent but when they come home to us they go back to their British accent, so I can deal with that.

One of my complaints with American TV characters is that they all have a particular schtick, a hook.
