I always think I love work, and I knew early on that I wanted to be an actress. Then I meet people who have truly dedicated their lives to acting, and I realise that Im so completely in the back seat.

I'm very different to my mum. I'm not as beautiful as she is, nor - she probably despairs about this - as groomed. I certainly rebelled against her idea of looking well turned-out. I spent several years with a shaved head in jeans and baggy shirts.

My stepfather introduced me to The London Library when I was about 18; the clientele has definitely changed since then, but it is still a wonderful oasis in the middle of London.

I always keep myself busy. I'm writing. Or I'm creating something. Or I'm doing stuff with the kids. I'm up incredibly early in the morning; I go to bed incredibly late at night.

I happen to find motherhood a very natural state, but I know a lot of other people don't.

Growing up, I wasn't allowed dolls, and my brothers weren't allowed guns. I inherited my brothers' clothes. I was never dressed in pink, and they were never dressed in blue; there were none of those rules that people still bizarrely subscribe to.

In terms of 'Solaris,' I didn't really think about the religious aspect an awful lot. There's one scene at a dinner party, and it's discussed, but it wasn't an overwhelming theme for me.
