Acting is something that I always wanted, but I never paid attention to the notion that it might actually work out. You have all sorts of ideas about what you want to do - at one stage, I wanted to be a jockey - but this is the one that's a big deal.

I did 'Nobody Walks' right after 'Dredd.' Well, actually, I got off the plane from Capetown where we shot 'Dredd' and tested for 'Being Flynn' that same day. Then I came out to L.A. to make this film right after that so it was all very back to back.

I'd always wanted to be an action heroine. That's a chick dream, getting to wear a leather bodysuit and be blonde and kick ass. But, what really attracted me to 'Dredd' was the script. It was fantastic! It was about people and characters, and not just about explosions and fighting.

I didn't have an incredibly active social life as a teenager. I always wished it was a little bit more exciting than it was.

I think 3D can be an incredible thing on a movie and a terrible thing for a movie, depending on what kind of movie it is. And I've seen movies where I thought the 3D really enhanced the experience, and sometimes where I thought it just detracted from it.

I can say I love working with women. Film is a man's world, and I really appreciate the opportunity to collaborate with women, especially young women.

I don't believe that if I came out as bisexual the world will change. But it's really important for people to be truthful about who they are and fight for equality. We need to help the world usher itself into the next phase.
