I remember when I was 26. My father died when I was young and my mother didn't have a lot of money, so I thought, 'I want to own a flat by the time I'm 26.' So I worked towards that, literally trying to scrimp and save. But sometimes those plans don't go as you expect.

No, it’s very comforting actually, to know that you’re sitting in a long legacy of actresses who’ve played the role. I’m absolutely all for absorbing all of those influences, so you understand the pedigree of the part as much as you understand the figure in history… because you are playing the part. You don’t say: “Gosh, I want to play Peter Sellers…” because you can sort of do that in your own bathroom.

You learn an enormous lot through failure.

I don't have a sense of entitlement or that I deserve this. You'd be surprised at the lack of competition between nominees - I think a lot of it's imposed from the outside. Can I have my champagne now?

It was fantastic to be able to have my kids on set. Dash, my eldest son, who’s not quite five, was into knights and his godmother had given him a plastic Marks & Spencer knights’ outfit and [first assistant director] Tommy Gormley said that he could stand to protect me during the scene where Clive [Owen] is talking about the immensity of sitting on the throne. I’m actually looking through an archway at my son standing in his knights’ costume protecting me!

I couldn't possibly have played someone with feelings towards a woman unless I had those feelings myself.

People talk about the golden age of Hollywood because of how women were lit then. You could be Joan Crawford and Bette Davis and work well into your 50s, because you were lit and made into a goddess. Now, with everything being sort of gritty, women have this sense of their use-by date.
