This document discusses narrative structure in horror films. It explains that most commercial films follow a three act structure of a beginning, middle, and end. The set-up is the first 5-10 minutes where the main characters, storyline, location, and genre are introduced. During the set-up, a catalyst kicks off the story and a central question is posed that needs resolution. Turning points change the story's direction and raise stakes, while the climax is the big finish where good and bad meet. The resolution ties up loose ends. Students are tasked to watch openings of past student horror films and evaluate how tension rises and falls through specific elements.
