Your film is like your children. You might want a child with certain qualities, but you are never going to get the exact specification right. The film has a privilege to live its own life and develop its own character. To suppress this is dangerous. It is an approach that works the other way too: sometimes the footage has amazing qualities that you did not expect.
Werner HerzogWhen you look at my film you see footage that is unbelievably awesome and beautiful and dangerous looking. It's something that is very, very cinematic.
