I knew it was going to be important that if I had an audience understand who she was, then all those things had to come from a place that was grounded, as opposed to being tics and manners and twitches. I didn't think it was going to be as rich, perhaps, as if I was going to make it more emotional.

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?'

There were days when I would say, 'God, I can't be without Leo'. He was my rock. We were such a team, nothing could break us, nothing could come near us.

I believe it is important to go on insisting that normality is not what we are exposed to. Honestly, among my acquaintances there is no woman wearing XS. No, sorry, there is one: my daughter. The point is that Mia is 11 years old. It's true that you need much time to get rid of the fat girl you once were, but you know I am sincerely grateful for my buttocks.

Since I was 13 or 14, I've always felt older than I actually am.

The highest compliment I could ever receive about my kids - and I can say that this does happen frequently - is when the in-flight crew say to me, 'Your children are wonderful. They are so well-behaved.' Every time I am told that, I could weep.

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.
