I think we all have a general sense of how important the final score is for a film. One of the things that is difficult from the director’s point of view is to edit a film with only the comforting notion that sound will come in later and put a button on the emotion of the scene. The Empire Strikes Back is one of my favorite films. So to be able to see it in a rough form, and how completely unremarkable it feels without the soundtrack, gives us some insight into the timeline of a film and how it feels during different parts of the process. When Lucas made the original Star Wars, before John William’s score, most of the people who watched the early cut considered it a failure. It is pretty safe to say that John Williams deserves credit not only for creating a brilliant score that can be enjoyed in complete separation from the film. But Williams also succeeds in the more important task of giving meaning to each scene and allowing us to feel the film in a way that’s not possible visually.
