I'm keen to have balance, as much as possible. I put every ounce of myself into my work, but also it's important that I don't miss every single wedding of my best friends. I couldn't do what I do without my friends and family.

But for everyone, I think, there is always a pressure to conform, and I guess as you get older you realize it's less interesting to do that. It starts with you, though, saying, 'I know what I like doing and that's what I'm going to do.

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.

I would work as hard as possible at school so I could keep acting alongside.

Acting has always existed alongside my normal life. It's been a case of learning on the job. I've worked in so many styles, with so many people, so I've picked bits up from everyone and everything.

I think good things come out of having tension with the people that you work with. You've got to be arguing in order to produce something interesting. If everyone's just agreeing with each other, you're not going to push the boundaries.

I've never taken a role where I don't like a person on the page.
