Filming is long - you get very tired, and your skin breaks out and you get lumps and bumps. It's easier if you're allowed to have bags under your eyes.

I'm not going to get an Oscar at 30 - that's done. So I'll think of something else.

I'm always nervous taking on a period role because it's difficult to research - you can't observe it, go out and see it. But it's satisfying because eventually you think, 'I got there.

I like doom and gloom with a sense of humour. Maybe it's a Scottish thing, we like to undercut indulgence with a laugh.

You suddenly find yourself somewhere and you wonder, how did I get in this room? That happens to me all the time, every day!

I spend plenty of time in London and it doesn't scare me, but it's a lonely place, even if you've got friends there. My job takes me all around the world, meeting lots of interesting people. But I think if I couldn't get home, if I couldn't get back to what I consider my real life I'd be frightened.

When I'm doing theatre, I feel like my life's on hold. Even though you might go out for a coffee, or go and see a film, your brain is still there, pulling you back to it.
