Apart from The Holiday, I haven't really spent a huge amount of time in LA. Not that I avoid it, it's just that I don't often go there unless I'm doing press. The one thing I have discovered about LA with kids is that it's really great for children. They really like the sun and making sand castles.

Having just had a baby, I'm not going to be thinking about my arse.

People say to me, 'You seem to have made this conscious decision to do independent films'. In reality, I haven't. After each movie, I always think, 'how different can I possibly be? Is this going to challenge me, is this going to inspire me, and is this going to make me love my job more than I already do?'

For my own children, I do want for them to look back and remember that it was me in the kitchen, that I was doing the packed lunches, that we were there on the school run, that we did take a bus. I want them to remember those things, because those are the things that I remember from my own childhood and that have been incredibly important to me.

It's my chance to challenge myself to the fullest, which is one of the great joys about my job... I love it when a character requires me to look less than my red-carpet best. It's more fun playing a character that requires you to look like dog s - t.

Ah, my dad's whistle. On holidays when I was a kid, we would all be off in the rock pools along the beach. When it came time to go, we'd hear the whistle and we'd all come running. Like dogs!

I'm not very technically minded. I mean, I don't know how to do e-mail on computers.
