The document discusses two narrative theorists - Vladimir Propp and Gustav Freytag. Propp identified seven character archetypes that commonly appear in narratives, including villains, helpers, and heroes. Freytag analyzed narrative structure and identified five parts of a dramatic storyline: exposition, rising action, climax, falling action, and resolution. The author explains how they applied Propp's character types but not Freytag's structural model to their film project in order to keep viewers constantly surprised.
