I get very close to people when I'm shooting them. We would go and shoot a scene with Lucy, and I would spend the whole time telling her about Rob. Then I would go shoot a scene with Rob and tell him all about Lucy. Eventually they wanted to know each other. These are two people who would never have overlapped in any other way or context. We brought to the garden at Rob's office and just sat and watched what unfolded. I remember weeping behind the camera, because I was so moved by the way they connected.
