I look completely like my mum. She's very foreign, very Jewish.

It took me so many years to move out. I'm definitely a bit of a Peter Pan, reluctant to grow up. It all seemed really nice at home-why change it? Part of me would prefer not to have any responsibility whatsoever.

I enjoy those small chats you have when people come up and talk to you about your work. It only involves a few seconds of effort to be nice to those people, and I am very grateful for the kind words that people have taken the trouble to express to me in person.

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.

When you write for very young children what they want is something familiar and safe and stereotyped.

Very early on, you figure out that you put your self esteem in the hands of strangers. There's a different commodity. There's the Helena Bonham Carter that everyone thinks they know, who really has nothing to do with me. But you just have to let that go.

All the ancient classic fairy tales have always been scary and dark.
