This document discusses narrative theory and its application to analyzing horror films. It introduces three prominent narrative theorists - Tzvetan Todorov, Vladimir Propp, and Claude Levi-Strauss - and summarizes their approaches. Todorov viewed narratives as progressing through equilibrium, disruption, recognition, attempt to rectify, and new equilibrium. Propp identified character archetypes and their narrative functions. Levi-Strauss saw narratives as organized around conflicts between binary opposites. The document aims to consider if narrative theory can be a useful tool for discussing storytelling methods, traits of the horror genre, and hidden ideologies in horror film narratives.
