This document discusses various concepts and theories related to narrative structure in films. It begins by defining narrative as "the way in which a story is told". It then discusses common linear narrative structures in Hollywood films and some films that break these conventions using non-linear narratives. Several theorists are discussed, including Levi-Strauss who analyzed how binary oppositions create meaning and propel narratives. Propp identified common character archetypes. Todorov outlined a conventional 5-stage narrative structure that can be simplified to 3 stages - beginning, middle, end. Barthes discussed narrative codes that engage audiences like enigma codes and action codes.
