The document provides information about several theorists and their approaches to analyzing narratives, including Vladimir Propp, Tzvetan Todorov, Roland Barthes, and Claude Levi-Strauss. Propp analyzed folk tales and identified common character archetypes. Todorov proposed narratives follow five fundamental stages: equilibrium, disruption, recognition, attempt to repair, new equilibrium. Barthes described texts as having multiple meanings accessed through different codes. Levi-Strauss found narratives are structured around conflicts between binary opposites. The document discusses how these theories can be applied to modern narratives like films.
