L.A. is brilliant, but however long my trip is I'm always ready to leave. But New York I'm never quite happy to see the back of.

A few years ago, if you had told me I'd be moving back to Glasgow I'd have said, 'No way'. But it's changed. It's much more vibrant, bohemian. But I'm 35 and I've become a bit of a homebody, I don't really go out much. Same in New York. My home could be anywhere but I love Glasgow.

They're naughty, all those writers - they mess around with people. I know James Gandolfini got a bit fed up on 'The Sopranos': if he said anything in front of a writer, told them a story from his life, it could make its way into the script.

It's that TV thing. You can be in the biggest film of the year and it will still not have the kind of impact a TV series has. Once you're in people's living rooms, that's it. There's no hiding place.

What I'm normally associated with are darker, more brooding roles.

I'm so not a celebrity.

It was both comforting and terrifying to go in to audition for 'The Girl in the Cafe,' as I'd worked with everyone in the room on 'State Of Play.'
