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.

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.

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 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.

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

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.

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

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.

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.

Scribbling things down is my therapy. I filter later.

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