My skin may have wrinkles but it's because I'm smiling so much. That might sound like some terrible American greetings card, but I feel it's immoral for me to castigate my body for getting older, when it does everything I ask of it.

My husband Rhashan reminds me of my father because he's got great strength of character.

I thought "I've coped with some crazy situations, and I can do this." But working with Roman Polanski is so different from the fashionable and accepted way of directing now.

I don't feel under pressure to work because I love what I do and I wanted to do the projects that came my way.

I didn't know box office was a thing you could possess but I don't have it. I go up for lovely roles and people with this nebulous thing called box office get them so there isn't much I can do about that unless you know where I can get some box-office myself!

Carey Mulligan is completely self-possessed. She knows what she's doing, and again, quite like the big-hitters I was talking about, my job was just to feel and reflect back the amazing performance coming my way. If anything, I was slightly pathetically flying in her tailwind. She's an extraordinary actress.

Ewan McGregor and I said this to each other after we saw The Ghost Writer. Every time Roman Polanski did a "No, no, no!," he was right. It was really as if a sculptor was asked to sculpt the embodiment of despair - that was the attitude he would strike. But as with every sort of inspiring teacher you ever had who was strict and scary, when you get it right, the sun comes out, and it's worth it.
