Acting is something that I've done since I was so young. I always felt - certainly as a teenager - really cynical about acting. I definitely didn't feel like it was something I wanted to do, and so I really took it for granted.

I am aware that I've generally been more attracted to introspective roles, but it's sort of bizarre, because it's the opposite of who I am in many ways. I think I'm quite an extroverted, loud person. So it interests me that that's sort of the place that I go all quiet, is when I'm onscreen. It's a bit strange.

Plus, doing a zombie movie is quite liberating. It's fun not to take myself seriously all the time.

I always look for an intense experience, an intense ride. There is nothing better than a good zombie movie where you run crazy and blow at monsters! It was a physical shoot and I enjoyed it.

There is no point trying to figure out who is guilty or not at un-balancing the planet. I think we need to figure out and solve the problems together and not isolate from each other.

Playing roles that are intense and damaged has always come more easily to me than doing comedies or lighter stuff - that would be taking a huge risk for me.

Lately I did a film called All I Want for Christmas and it was well received. This gave me a new point of view and a new respect for my work as an actress.
