"The Theory of Everything" is an extraordinary story because [Jane Hawing] was incredibly religious and [Stephen Hawking] was an atheist, so you have this conflict both on a domestic level between a couple in a difficult situation but also this bigger conflict of science versus religion, so it's a really fascinating project.

I like Nelly's [Ternan] quiet inner strength. I thought there was something about her predicament that I found interesting - that she didn't want to be a floozy mistress, a bit on the side, that she had more self-respect than that.

I was a tomboy running around in the garden. I used to play on a local cricket team. I grew up with all boy cousins, for the most part, and my brother. My mother was in the kind of late-sixties, early-seventies origins of female emancipation. And she was very much like, "You're not going to be defined by how you look. It's going to be about who you are and what you do."

I do sort of appreciate Nelly's [Ternan] view that it would be woman who would suffer mostly from that - who would be ostracized. The rigid societal conventions meant that it was difficult to live outside of them.

It was lucky that Ralph [Fiennes] is someone who understands both film and theater and we were able to understand that scene so well before we took it to the set.

There's so much of a desire in the entertainment industry for newness, a desire to build somebody up and then treat them as old news within six months. I think you'd be naive if you didn't try to hold on to your own way of doing things.

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.
