I have read both the original Robert Towne draft of Chinatown and Polanski’s rewrite. That should go down as one of the great rewrites in movie history. It was the work of an artistic genius, and produced one of the most iconic and well-crafted movies ever to come out of Hollywood. Nothing can take that accomplishment away from him.
But Polanski should be arrested, tried, and spend the rest of his miserable life in jail because he raped a child.
