You can spend an entire day walking around in New York, whereas in L.A., it always ends at some point because you have to find a way to get home.

I wanted to be a musical theatre actress - I wanted to play Sally Bowles, forever and ever always.

People get married when they're 18 and spend their whole lives together. I think their greatest fear is that someone will see it as a fling because they were young and it didn't mean anything.

I was quite straight-laced. I was quite academic until I was about 14 and then I went to boarding school where I had the opportunity to continue to be very academic, but got less interested in it and became more involved in acting. And then when I was applying for universities I used a couple of places on my UCAS form to apply for drama school without telling anyone... but didn't get into drama school. But that was the most rebellious thing I did.

I grew up with an older brother, so I'm pretty good at being bashed around.

When I went to the Oscars - the only time I've ever been to the Oscars - a few years ago, I wore this Prada dress covered in cooking utensils. I got drunk at the end of the night and started ripping them off and giving them as presents to people, so that was fun. I'm pretty sure that was the point of it, that's how Miuccia meant for it to go I'm sure.

The toughest part of acting is never a single thing. It's more like a whole character. I find film really difficult - trying to make it feel like a consistent character when you're filming everything out of order.
