I'm scared of actors with a scheme.

It's important to travel and move and have a continual set of experiences so you've got more to feed back into your work. For me, it's a natural thing.

Culture civilizes us, and that's why every single despotic regime has tried to smash [the arts].

Film just chews up actors like nobody's business, and I'm not particularly interested in being chewed up. I think the camera can only look at somebody's face for so long. I guess you have to accept the roles you think are right at the time. You can build a career, but these days there doesn't seem to be that much interest in people being actors.

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.

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!

o matter how much research you do, or invention you do, whether it's a character from a novel, a completely invented character or someone who actually existed, it's a work of faction. By the very fact you only have an hour and a half or two hours to tell a story, you're telescoping events and it is, in the end, a work of imagination.
