Alicia Vikander

I push myself hard. I don't like pain, exactly, but as a ballerina, I lived in constant pain. At ballet school in Stockholm, I remember we had a locker where if someone had been to the doctor and gotten painkillers, we divided them among us. In a sense, we were all addicted.

It's a mixed feeling when everything you've ever wanted in making films is coming true, and yet you feel scared because it's happening all at once. Suddenly you're in rooms with people you've looked up to for years, the Judi Denches. You wonder if you're good, if you have what it takes.

The Yas Marina circuit is really pretty impressive. The track itself has some quite slow corners and not a great deal of overtaking opportunities, but it seems to combine a road course with a circuit course.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
