I'm a dual citizen, as are my husband and children. We have got eight passports between us; we're weighed down by them whenever we go anywhere.

The harder the circumstances under which you're making a movie, generally the better the friends you make. You're far away from home and so you're kind of lonely, and you end up all gravitating towards each other and the bar every night. It tends to be inversely proportionate to the comfort level on the movie, how close you become to everybody.

I want any excuse to come home. My dad is not a spring chicken any more. If anyone says, 'Go buy a postage stamp in London,' I'll go and do it.

Accents are very tangible, blessedly, and if you have to do one, it's a way of getting into character. I can read it through a few times and pretend I know what I'm doing!

I had friends at school, but I was never part of a gang and I dreamed of that sense of belonging to a group. You know, where people would call me 'Em' and shout across the bar, 'Em, what are you drinking?' after the show.

I'm physically completely mal-coordinated. My best friend used to make me run for the bus just to give herself a quick, cheap laugh because I definitely don't have that sophisticated cool thing down.

I was determined not to become an American citizen but I did it for completely cynical reasons: to avoid paying inheritance tax in the U.S.
