I've done quite a lot of improv work before, and I wanted to do this film ["The Invisible Woman"] because it felt like a different technique. We were very true to the lines, and there was something quite formal and almost theatrical about it.

I made a film called "The Theory of Everything," which is based on Jane Hawing, who was married to Stephen Hawking - it's based on her book about their relationship.That's what the film will be about - they were both incredible, strong, willful individuals and I feel like that Stephen Hawking himself would say that he wouldn't have survived without the influence of Jane Hawking, and they were an incredible team together.

There's such a sense of theatre in getting glammed up; it's like putting on a play or short film.

I guess I'm a bit of a romantic.

I'm very independent, creatively, always trying to push myself - and I think that comes from my mother.

I always had a very strong sense of independence. I really liked being able to buy my Alanis Morissette Jagged Little Pill album. I wore that as a badge of honor. I love not having to rely on anyone.

It was amazing how much rehearsal helped with the performance - it was almost a theatrical approach to filmmaking.
