"People often repeat the fallacy that "film is a passive medium". The statement is usually elaborated like this: "When I read a story in a book, I have to use my imagination to conjure up what the characters look like, the sound of their voices, the appearance of their surroundings, the house, the landscape. When I see a movie, those things are all nailed down for me, so I don't feel as involved." What the person is describing are the most obvious aspects of a given story, that is, its physical properties. They are, in fact, the least interesting and least important components of a story. I do not read books in order to imagine the physical appearance of things."
