This document discusses linear vs non-linear storytelling in films. Linear films follow a chronological order from beginning to end, while non-linear films do not always unfold chronologically and can be disjointed or disorienting. Examples of non-linear films include Citizen Kane, Memento, Eternal Sunshine of the Spotless Mind, and films by Quentin Tarantino. While non-linear films may not follow a traditional 3-act structure in order, they still need structure, tension, and forward movement. Planning is important to provide a "spine" and structure, but there is also value in improvisation and finding creativity within established guidelines.
