I fell in love at 14 and I remember that mad, tense feeling and all the mad things you do for the person - all those extremes and all the stuff you don't mind putting up with.

I love the challenge of playing characters forced on life-changing emotional journeys. To work on a project with Billy Crudup and Sam Rockwell is just a dream come true.

I was lucky enough to get a very good agent at the age of 15, and got my first film when I was 16, so it's been rolling on since then.

I'd imagine a great date would be to go skiing. Imagine going skiing. Go ski with someone, if they can ski.

Nothing's been changed overnight. It's like watching your cat grow: you see it every day, so you don't really see it change, you wake up one day and it's a bloody great thing. Your friends come round who you haven't seen for a couple months and they're like, "Oh my god, your cat's grown so much again." And I'm like, "Has it?" But when you're living it... I just find that my life has subtly changed bit by bit, so I don't ever really notice it too much.

The most romantic things are very small, kind gestures from people you love.

I've had friends who have come away who've said, "I shouldn't have become such close friends with the director." You always want to get on with the director, but I personally prefer a relationship where you respect them - you get on really well with them, but they're boss, as it were. It's about trusting your director, for better or for worse. They're the one's seeing what's coming out on the monitors, so you have to try and trust what they say.
