Growing up, the image I had of Princess Margaret was completely different. I knew that she was a slightly tragic figure, but I didn't know why. Now, I love her with my all my heart. She was such an amazing person, and getting to 'know' her better was an honor.

I did The 'Acid Test' at the Royal Court, by Anya Reiss, who's the most wonderful, amazing female writer. She was only 19 when she wrote it. She wrote it about three girls in a flat on a Friday night, and that was magic because it was so rare to have three girls in your age group in a play. It just doesn't happen.

I thought, 'If I go to uni, I can read and watch people and take many different subjects - take philosophy modules - and have time to travel in the summers,' which I did. I thought, 'I hope this will make me a better actor,' and it did.

Acting is a very weird job. But if you know you're an actor, you just have to do it. You can't do anything else.
