This document discusses different types of narrative structures in documentaries and films. It describes Vladimir Propp's theory that stories follow archetypes of eight character roles. Todorov viewed narratives as having an initial equilibrium, a disruption, and a restored equilibrium. Narratives can be linear with chronological order, or non-linear using techniques like flashbacks. Endings can be open-ended leaving questions unanswered, closed with no loose ends, or circular ending where it began. Narratives can also have a single or multi-strand structure following one or multiple storylines.
