My mother was in advertising and worked incredibly hard when she was bringing us up. She was a working mother and a working single parent. That instills in you a sense of determination.

Now younger actresses will have a confidence in those discussions with their agents and be able to say, "Can we make sure that I'm being paid the right amount for the work that I'm doing?"

You have to be brave and not always play likeable people. It's difficult, because there's a demand for the hero or heroine to be very likeable.

I have a great plain blue shirt from APC, and a denim one from Dolce that I wear constantly. It's hard to find the perfect denim shirt, but this is it.

I hate it when, in films, the girl looks perfect in every shot. It's quite nice if there's a bit of dark circles underneath the eyes, if we see the reality of the situation that the person is going through.

I don't have much time for shopping so I pick things up when I can. My favorite labels are APC, Isabel Marant and Agnes B because the clothes are cut small and have a simplicity to them.

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.
