In a world awash in screenwriting books, The Science of Screenwriting provides an alternative approach that will help the aspiring screenwriter navigate this mass of often contradictory advice: exploring the science behind storytelling strategies. Paul Gulino, author of the best-selling Screenwriting: The Sequence Approach, and Connie Shears, a noted cognitive psychologist, build, chapter-by-chapter, an understanding of the human perceptual/cognitive processes, from the functions of our eyes and ears bringing real world information into our brains, to the intricate networks within our brains connecting our decisions and emotions. They draw on a variety of examples from film and television -- The Social Network, Silver Linings Playbook and Breaking Bad -- to show how the human perceptual process is reflected in the storytelling strategies of these filmmakers. They conclude with a detailed analysis of one of the most successful and influential films of all time, Star Wars, to discover just how it had the effect that it had.
