I don't know what kind of swag I'd get if I were extra Irish. It would just be, like, extra potatoes. Or like a free pint of Guinness.

For me, clothes are about individuality. When I wear things that are different and it works, it makes me feel good.

I've always been quite an active person especially when I was younger. When I was in primary school, I used to play lots of sports. I was a sprinter and I did basketball and swimming and Gaelic football and things like that. So I always thought, I guess, that it would be fun to incorporate that much physical activity and work into a dramatic piece.

I was 12 and I remember every­thing. I mean, I had done two films before that. The first was actually with Amy Heckerling. It was so brilliant to work with her on my first film. Atonement was the third one I'd done, and I remember how it felt to arrive on set every day. I remember how it felt to get my wig off at the end of the day. I remember how hot it was.

I like films where there's a relationship between two women. I always think that's lovely to watch on the screen.

'Romeo And Juliet' is the classic love story. When two lovers are separated and trying to get back to one another, that's fiercely romantic and something you become glued to.

One of the things that would steer me away from a franchise is that I'm playing the same character all the time and I wouldn't want to be known for that.
