I think that I burnt myself out a little bit with my dancing because I did so much of it. I was exhausted so thought that I would try a different kind of performance and expression and acting seemed like a close fit; it was similar in some ways to dancing. My mum showed me some really good films and so I became interested in films and acting.

When I got onto set with him we were given a folder of storyboards. I thought that was pretty incredible because I hadn't worked with anybody who used storyboards before so he obviously had a very precise way as to how he visualized the film from the very beginning. It was every scene, but to his credit he was incredibly collaborative and gave us many opportunities to have our own input and to change things with him, so it was a really great way of working.

Ballet has really helped me in every acting role. You have to be very disciplined, you have to be able to control your nerves and perform under pressure, and all those things you have to use in acting when you're on film or going for an audition.

I didn't shoot any guns then or when we did the scene with Uncle Charlie [Matthew Goode] and Evie [Nicole Kidman] in the hall. I sort of pressed the button but there were no blanks or anything in there because I think it was always going to cut.

One of the producers, Wonjo, was an amazing interpreter. I don't think we really knew how it was going to work at the beginning. Yet it was something that a couple of days into it seemed so seamless and it wasn't something that we noticed or thought about. A couple of times I cornered him and forced him to speak English but we didn't speak much English at all. That said, I don't think anything was ever lost in translation. It was all very easy.

I've had a great experience with pretty much everybody I've worked with.

Director Park asking that if there was a pocket on one side of the piece of clothing then there should be a pocket on the other side. They were a little uncomfortable to wear, yes, because there were a lot of tight, high-waisted things so it was great at the end of the day to slip into some pajamas!
