Emotion and Understandability in Screenplay Writing - Eugene Vale
"In order to make the story content understandable, it would seem necessary to choose factors which are well known to the spectator. But this is a fallacy. In the very first part of this book, it was said that the primary desire which forces a person to listen to stories is the wish to partake in the lives of others or to get information about the way others live. This desire is in direct contrast to understandability based on his knowledge, because he wants to learn things which he does not know.
"This apparent dilemma has led to much confusion among producers. In order to satisfy understandability, they would make pictures about average people and, more or less, average events. Although the audiences understood these pictures, they were not interested in them, because they wanted information about things which they did not know. It seemed that the audience preferred to see emperors, adventurers, exotic people, or freaks on the screen rather than to see themselves portrayed. If a producer then went to the other extreme, he found very often that outstanding personalities or extraordinary events were beyond the reach of the average audience; they could not be understood and therefore were not successful.
"To illustrate this confounding difficulty, we need only think of a classic picture like The Bicycle Thief (1947), which was a success everywhere except in its country of origin, Italy, where the events were too familiar, and its neo-realism too close to home.
"The solution for this problem is not simple: the audience wants to learn new and interesting facts that should contain the measures and values which are universal knowledge. Few people are in a position to evaluate and understand the conflicting diagnoses of two brain surgeons. But everyone will be able to understand exuberance or fear. Few people will be able to evaluate an investment banker's decision in a stock issue. But everyone will be able to understand the conflicts resulting from a gangster's violation of law and justice, because the law is universal and all people are subject to it.
"Therefore the problem must be solved by giving new information which can be measured and evaluated on the basis of universal knowledge. And the most universal knowledge among all human beings is the experience of emotions."
