I wouldn't go down the route of having an assistant. I don't want to be like that. I want to be normal.

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 love New Zealand. It's my favorite place to shoot. It's one of my favorite countries to visit. The people, the food, the landscape, everything about it I love.

I've basically grown up with Harry Potter, as so many kids my age have. It's kind of a part of my life.

When I was younger, I would mess about and have a laugh with everyone. I was doing Atonement when I was about 12, and as we went to do this very serious scene, the director Joe [Wright] came up to me ... I'd been giggling right up to the beginning of the take. And he came up to me and said, "Okay, you need to be serious now." I completely idolized him.

There's so many modern films where the fans take one side or the other. I'm hoping this isn't going to be like that; I'm hoping it isn't that kind of film at all. What I would love for the audience to take from it is to understand why she was so stuck in the middle and confused.

Everyone thinks I'm ethereal. But I'm not like that, you know. I'm not ethereal. Well, I might have a little bit of that quality to me, that 'old soul' thing, but I'm not ethereal.
