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

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.

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.

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.

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.

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.

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 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.

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