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

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

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 I didn't have children I might be more of a lush than I am. I like booze. I struggle with smoking. And I'm a big swearer. I'm trying to rein it in but I do think it's a nice seasoning of language.

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.

The first time I did a school play was the first time I felt I was good at anything at all. I just loved it.

If the script's good, everything you need is in there. I just try and feel it, and do it honestly. I also don't learn things for auditions, because I feel like it's just a test of memorizing rather than being real. Maybe every other actor would think that was terrible, I don't know. But it seems to have worked for me, so far.

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.
