I suppose I have played a lot of put-upon women, but it's never bothered me. They've never been weak - they've always got steel in them.

Actually, lots of women, when they're pregnant, feel like steel. They feel incredible.

I've always done drama, but I suppose 'Tyrannosaur' was a bit of a watershed moment for me. It was like when Kathy Burke did 'Nil By Mouth' - suddenly, people were saying, 'Oh, she can do that, too.'

I used to want to be in 'Downton' because I had never been in a period drama, but then I did 'The Suspicions of Mr Whicher' and had to wear one of those frocks and... I didn't feel very comfortable.

I was never one of those surly teenagers who doesn't smile. My lovely godfather said it was always lovely to see me because I was the only teenager who smiled. And I was so in awe of him, I thought it was one of the best things anyone had ever said to me. So it made me want to live up to what he said.

In general, I'm rubbish in heels. I love them, and I own a lot because it's like being in a sweet shop: they're pretty. But I'm not good in them. I don't walk nicely in heels.
