My parents' long and happy marriage was a great ideal to live up to, but a tough one.

Ewan McGregor is a very genial and entertaining man, and Pierce Brosnan is possibly the nicest man in the world. Actually, it was quite a genial set The Ghost Writer, but the weather and the colors and the actual surroundings were oppressive. But it was a created atmosphere. What was so striking is that Roman Polanski had his crew from The Pianist, and we were shooting in Berlin, so there were German and Polish and French people, and I was just sort of enjoying being in this mix of people, all kind of rubbing along together. That felt good.

There are movies where I've walked onto the set and felt, "This is home," and I'm confident in myself and my work, but that was my first experience of live TV. At that stage, Friends was at its unassailable height of popularity and brilliance.

When the Hollywood thing happened, I thought at some point I'd get to the front of the queue: 'Yes, hello, I'd like to play that role.' But you don't. You just join a different queue.

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.

The best Christmas present I got from my husband was a week to do whatever I wanted.

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!
