As an actress I take roles I find interesting.

I have a real thing for Mexican directors. And I love Guillermo del Toro and Alejandro Gonzalez Inarritu.

As I've got older, and since I cut all my hair off, I've felt a bit more liberated about trying different things out.

Most people are really nice but some stare, like you're some kind of zoo exhibit and not a real person with real feelings.

If I could wear any label forever it would be Burberry. It covers a huge span of stuff. You can't go wrong with a classic trench and a pair of jeans.

The character is everything that I felt really strongly against - she's superficial, materialistic, vain, amoral. She's all of these things, and I realised that I really hated her. How do you play someone that you hate? But I found it really interesting and it gave me a whole new insight into what my job, or my role as an actress, could be.

Harry Potter's like Santa Clause: something you can't see but wish was real so badly that you end up believing in it.
