With stores like Topshop and H&M you can find really great stuff, but I do like designer things as well, and I'm lucky because they approach me to wear their stuff. I really love Miu Miu.

Sometimes the director will want you to write about the character, sometimes he'll want you to live in the location that the character is from or something like that, but I don't usually make a lot of notes or anything like that.

I think it's important that we have strong, female characters in movies now, which can really leave an impression on people - especially young people - and that they're not 'sexy' or 'cool'.

I'm Irish, so I'm messing all the time. Which means, I'm having a laugh. I'm always making jokes.

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 try as best as I can to have a normal life. People recognise you, of course, and that's very strange. But I sort of leave my working life behind when I go home. That's my other world.
