This document discusses various narrative techniques and structures used in filmmaking. It begins by describing linear and non-linear narratives, as well as multi-stranded narratives that feature multiple storylines. It also discusses restricted and unrestricted narratives, focalizers that determine a story's perspective, and the use of ellipsis, closure, and the three-act structure. The three-act structure typically involves an introduction to establish characters and settings, the introduction of a conflict or problem, and then a resolution to that problem.
