The document discusses several narrative theorists and their theories for analyzing narrative structure in films. Tzvetan Todorov and Vladimir Propp analyzed narratives based on stages of equilibrium, disruption, and restored equilibrium, and types of characters, respectively. Roland Barthes identified five narrative codes used to create meaning. Claude Levi-Strauss recognized that narratives are arranged around conflicts between binary opposites. These theories can be applied to analyze the narrative structures in films, though their use may be limited in short films due to brevity.
