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.

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'm not a pin-up, thankfully. I'm not suggesting I feel unconfident. I am beautiful to my husband. I am beautiful to my friends. I feel sexy and all those things with the people I love.

If the script's good, everything you need is in there. I just try and feel it, and do it honestly.

I always assumed I would leave drama school and do 'Lady Macbeth' and all sorts of serious things. It just didn't happen.

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.

I am a bit sickie happy. I am prone to black clouds too, but... I am embarrassed about them. It's like: 'My diamond shoes are too tight. My money clip doesn't fit all my fifties.' I mean - really. Shut up.
