I think the difference between finding happiness, or moments of happiness, is how you choose to interpret things. That's a rather shocking responsibility. That we're responsible for our own happiness. It's not those around us.

I have a massive divide between being a competent human being and being completely hopeless, when it comes to logic.

I play Nitin Sawhney's 'Letting Go' repeatedly, nonstop. I find it transformative. I'm so glad iPods were invented so I didn't have to drive everyone around me mad with the repetition.

I grew up with my stepfather in Brighton, but I did spend a lot of time with my natural father, and I was loved by both, so I suppose the advantage of this was that I wasn't bound by one set of experiences I always had an alternative.

I think it's incumbent on actresses to bring something else to the part which isn't in the script.

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.

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.

I feel awful for women who are trying to raise kids on their own, with zero income and no fathers present - that's single motherhood.

My kids always say to me, 'Can we watch TV?' I say, 'Absolutely!' because then I can get something done. But then they say, and I wait for it, 'But can you watch with us?' My moment of freedom vanishes. So not only do I not think TV's that great and I hate sitting in front of it, but I have to with them.

Scribbling things down is my therapy. I filter later.

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.
