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.
The endings for all my characters seem sufficiently human and messy for me to feel comfortable with them. In some ways they have only moved an inch, but sometimes an inch is a great distance.
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 holy trifecta of directing and filmmaking is character emotion, camera movement and music. When you hit those three, that's magical. That's what I'm trying to do.
