The document discusses several narrative theories including those proposed by Tzvetan Todorov, Vladimir Propp, Claude Levi-Strauss, and Roland Barthes. Todorov's theory examines the stages of equilibrium, disequilibrium, and restored or new equilibrium in narratives. Propp identified character types like the hero and functions of narratives. Levi-Strauss explored binary oppositions in narratives, and Barthes studied narrative codes like enigmas that hook audiences. The document ends by discussing how aspects of these theories were applied to the authors' own film production.
