I just love real characters; they're not pretentious, and every emotion is on the surface, they're regular working people. Their likes, their dislikes, their loves, their hates, their passions; they're all right there on the surface.
The whole trick is to make it feel like you're spying on real people's lives as they get through the day. When I'm writing, I have to trick myself as a writer. If I consciously say, 'I'm writing,' I feel all this pressure and somehow it doesn't feel as real as when it doesn't seem to count as much.
I'm always looking for a way to surprise audiences. That's, I feel, my job as a director. I felt that Amy Adams playing a tough woman in 'The Fighter' was a surprise. People saw her as a princess.
The closer you stay to emotional authenticity and people, character authenticity, the less you can go wrong. That's how I feel now, no matter what you're doing.
I got put on jury duty, which is where I learned how to write.
