This document discusses the key elements of narrative structure in film. It explains that every film has a narrator, either first or third person, that provides information to the viewer. A film narrative depends on a protagonist character pursuing a goal while facing obstacles. Most narratives follow a three act structure, with the first act establishing the story, second act developing it through pursuit of the goal and obstacles, and third act resolving it. Good narratives keep viewers engaged by having imperfect characters and rising stakes. The screenwriter crafts the narrative structure, characters, dialogue and setting within the constraints of runtime. Order, duration, and creating suspense versus surprise are also important elements for the screenwriter to consider.
