That's the thing with animated films - I often feel that puppets get the better parts compared to us normal actresses.

J.K. Rowling said Bellatrix's role was going to be significant in the last one, when I showed some reluctance in playing a tiny bit part. Up front, they said, 'You're very significant in the last one.' But significant could mean a lot of things. That could just mean a significant plot point. Doesn't necessarily equal big part.

I also get fed up with the fact that casting agents and directors have this impression of me as being frail and petite. I find it very patronizing. I'm quite beefy and strong. I was a gymnast in school and I have lots of muscles.

I hate this image of me as a prim Edwardian. I want to shock everyone.

When you're up for an Oscar, you just get offered everything. It's fantastic, but a lot of it you're completely inappropriate for.

You become very angry and depressed that you keep getting offered only these exceedingly demure and repressed roles. They're so not me. That's why films like Fight Club were so important to me because I think I confounded certain stereotypes and limited perceptions of what I could do as an actress.

I think Woody Allen is pretty much of a genius. I'm thinking of filmmakers every century or two, but I've never had the luck to meet them. People who create their absolutely own world and are totally inimitable.
