"The literary story is hard enough, heaven knows. It calls for a thorough understanding of the kinds of people you set out to depict. It cannot be of high quality unless the author can plot well. And, of course, it must be cast in distinctive style. The picture of the silent screen does not demand literary abilities, but it does require insight into character as well as drama; furthermore, it is founded upon a high order of visual imagination. The stage play, in a certain sense, calls for all the chief abilities of literary stories and silent pictures; and, in addition, it must be managed with dialogue, which is some thing very different from literary language. But the sound picture goes beyond all of these other art forms. To invent a good one, you must grasp character, drama, settings, and dialogue. But you must go beyond these. You need a fanciful ear. The backgrounds of your story now cry out. The tale is filled with noises. And every least sound adds a unique quality to the total effect."
