I play the piano. I bought an upright piano that is actually electric, so I can practice my scales with headphones on and not make my neighbours' lives hell!

I give everything to my work, and I like complex roles, characters that aren't obvious. I've been very lucky so far, and I'm dreaming of working with directors like Jane Campion, Susanne Bier and the Dardennes. But the gods will decide.

I love fashion from the 1930s and '40s - shoulder pads, high waists, things with structure. That is classy for me. Andrea Riseborough from the Madonna movie 'W.E.' had an amazing wardrobe.

Traditional British desserts with lots of custard are my biggest weakness - I particularly love the puds at St. John restaurant in East London.

I don't like flirting, and when I love someone, I always give everything, maybe too much. And then you have to work at it all the time. I mean, the first months are always great, but afterwards it becomes hard work. It's not as passionate and crazy.

My father is Swedish and my mother is French.

Some people collect butterflies - I love beetles.
