The document discusses several narrative theorists and their theories. Vladimir Propp analyzed Russian folk tales and identified common character types like the hero, villain, and donor. Roland Barthes identified narrative codes that structure texts, such as the action code, enigma code, and cultural code. Tzvetan Todorov suggested narratives follow a three-part structure of equilibrium, disruption, and restoration of equilibrium. Claude Levi-Strauss stated that all narratives are organized around binary oppositions like good vs evil. The document provides examples of how these theories can be applied, such as to the film The Incredibles for Propp's characters and Toy Story for Todorov's structure.
