I really needed to have something in my life, because I realized there were other things more important than my career. So I love having my children and my family.

I love the ups and downs and the eccentricities of my career. The worst movies have produced some of the best friendships.

The phrase you usually hear after a cut is "That was great. Perhaps we could have another go. Maybe try it this way." Even that much direction is prefaced with a lot of praise and encouragement. It's quite like how you deal with toddlers: positive reinforcement, and then a little suggestion that you might want to try something different. Roman Polanski will stop the take and shout, "No, no, no!" Which is somewhat alarming the first time it happens.

I'm on record as having said "I've done this amazing movie - The Sixth Sense - that no one is going to see." And then it stayed in the top 10 American films for about six months. So don't ask me. I'm the most disastrous PR and marketing predictor.

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.

I couldn't get any of the ingenue roles when younger because at 5 feet 9 inches with a deep voice I was always too... genue. My career has completely happened since I was 29.

If the role is right and it's another situation of having a benevolent genius at the head of it, someone who likes actors, and will protect the actors from the ravages of reality-TV drama. It's a brutal world, and you need to have a strong creative team who can stand up to the network.
