I was a semi-professional gymnast as a child. I did rhythmic gymnastics, but I sustained an injury and strained all the muscles in my spine.

I'm certainly really rather tall at 6 foot 3, and I've been this way since I was 14, but for years, women who are even 5 foot 10 have come up to me in the street and said, 'Oh, it's so nice to see a woman who is taller than me. I've always felt like a giant.'

They told me I would find it difficult to find work because of the way that I look and they weren't wrong. [laughs] I thought, "Well, I'll prove you wrong" because I genuinely believed that the world was a more diverse place than they perhaps viewed it to be.

I was really, really lucky because I have always worked. It hasn't always been consistent, but I have always worked.

I had done lots of theater and I really wanted to do screen work. I said to my agent, "Look, I really want to do screen work and I want to concentrate on that now" and he said, "Well, it's going to be tough for you."

I read the books and I really, really wanted to play the part. I started kundalini yoga, kickboxing and running, and completely changed my diet. I felt I wanted to undergo what was necessary for the part. I love a challenge. And I love defying limitation, gender stereotypes and people’s expectations of me as an actress.

I heard that a lot and I just sort of thought, the world was an even more interesting place than the people who were making the decisions were perhaps interpreting it to be.
