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.

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 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.

That's what acting is. You're pretending to be someone else.

'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.

I don't mind doing the whole red carpet thing when I have to when it comes to publicizing a movie. But besides that, I don't like those kinds of things at all. Celebrity status is not really something that appeals to me.

I don't feel isolated on a film set. In a way you do because you don't really mix with the outside world; you're just sort of working non-stop for a few months, but you've got so many people around you.
