In 'A Royal Affair' I had to learn to act like a queen and learned Danish. It's so much different to act in another language. It's the nuances in the words.

My dad read 'The Danish Girl' and fell in love with it. He told me, 'You need to do this film.'

I vividly remember watching women in films when I was nine or 10, picturing them being what I'd be like as an adult. I had these real female crushes on certain actresses. And I'd watch them, thinking, 'One day, I'll be that. One day I'll be a woman.'

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.

I endured quite a few injuries when I was younger and had my first surgery on my foot when I was 15. But I love dancing. 'Anna Karenina' was great for me as it meant I could combine the two and I actually went back and did some classes.

I'm a real Swede! In fact, I'm a quarter Finnish.
