I think that when you're an actress, you have to think about what kind of a role model you're going to be. I hope that I'm a good role model for young girls. I'm not going to, if people still want me in their movies, I don't want to be one of these girls who goes around partying every night and is in rehab. I don't want to do that.

I'm very much for strengthening our industry at home. It's great now there's a lot of work happening but I think with Irish film in particular, the views were starting to get a little stereotypical and we were pigeonholing ourselves a little bit. We needed to get out of that.

There are a lot of people who say, 'Yeah yeah, I'm a feminist,' and they're not, actually. I wouldn't want to throw that word around, because it's a very strong thing.

I certainly don't feel like I am desperate to run away from a film set. I love the hustle and bustle. Everything is sort of mad right before a take, and then it just settles, and you've got these two minutes of a bit of magic. I just love that in film.

Vampire teeth really aren't very efficient, are they? It looks very messy. I'm not sure it's the best way to get a pint off anyone.

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 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.
