I love cleaning. I love mopping the floor. If you need your floor mopped, I'm there.

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.

I remember being on Atonement and it felt very right to be there. There was so much excitement every day. I remember very vividly how it felt to be a child on a film set, and that is actually really important to hold on to for as long as you continue to make films.

I play basketball, I surf and swim and go to the cinema and listen to music and read. I like shopping.

When I am on set or rehearsing for the play, the only thing I can talk about is the work I'm doing. In that way, I home in on what I am doing at the time. So maybe I am a terrible multitasker.

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

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.
