One of the great privileges of having grown up in a middle-class literary English household but having gone to school in the front lines in Southeast London was that I became half-street-urchin and half-good-boy at home. I knew that dichotomy was possible.
I have women coming up to me and saying: 'I love your character! She's so empowered. She takes control she gets what she wants.' That's another side of her. And I respect that in Joan. She says and does things that I would never allow myself to do.
