I also know what looks good before the camera, how to move the camera, and how to get a story on the screen.
I love it when characters surprise you, just like real people. When I write a scene I just try to make the characters behave in a way that feels natural to them. Sometimes that means they make a left turn and do something unexpected. Those are always the best scenes in my opinion.
As you get older, you sometimes feel that it's harder and harder to get something new and wonderful to come into your life.
