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.

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.'

I've done TV and I've done film, and I'm not snobby about it. It's about the project.

I don't think you can be involved in film and not be a fan of theirs. The one that I just go back to and can watch anytime it's on TV and I'll watch to the end, is Fargo. I think it's, like, a perfect film, it's genius.

It's just the way I'm made. I do feel confident in what I do. It doesn't always work out 100% of the time, but generally I think I can do it quite well. But the other part of my job is doing the press and stuff. And I'm rubbish at that. I'm really not good at that at all - this quite important part of what I do.

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.
