This may sound mad, but you sort of assume that no one's going to watch what you do. You go on set, have a lovely time, and then you forget anyone's going to see it. So it's always a bit of a shock to be recognized. I get terribly embarrassed.

I had a lovely, feral, free childhood - out and then come back when you're hungry or it gets too dark. I feel slightly cruel that I'm not offering my children the same.

In fact I was slightly badly behaved at school and got in trouble. I would get a bee in my bonnet about something I thought wasn't right, and I would ape about too, to make everybody laugh. That was my way through my girls' school, because I wasn't very academic.

You see thousands of films you forget the minute you come out of the cinema, don't you? Because they don't mean anything. It's the tough ones like 'Breaking the Waves' and 'Nil By Mouth' that stay with you, that you never forget. I'd like to leave a few of those behind if possible.

I feel fortunate that I'm not a beauty. I'm not a classic beauty. I feel it is harder for girls who are like that. There are fewer parts.

Everything with me is pretty close to the surface, but having kids has completely ruined my emotional equilibrium.

If a script is good, you are 10 steps into the part just reading it. But my choices are not all down to my taste. It is about people you have worked with before.
