I wasn't frightened of people, but I didn't have a clue about the adult world.

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.

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.

I never get the tall, blonde, glamorous roles because I'm not tall, blonde and glamorous. I'm more the wee, disturbing characters because of the way I look or sound.

It's such a stress always trying to get bigger houses and larger cars and better schools. Of course, parents want to give their children the best opportunities in life, but sometimes that can stifle them.

I don't have children, but we all want to protect whatever we love in life.
