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.

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.'

I love whiskey and haggis. I can't get enough of either.

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