Structure is not a formula — it is the invisible architecture that makes stories land. These six frameworks represent the major approaches to organizing a screenplay, from Aristotle to Dan Harmon. Learn the principles behind each, then use them as tools, not rules.
Aristotle (Poetics), popularized by Syd Field
The three-act structure divides a screenplay into Setup (Act 1, roughly 25%), Confrontation (Act 2, roughly 50%), and Resolution (Act 3, roughly 25%). Each act escalates conflict and transforms the protagonist. It is the foundational framework behind virtually every Hollywood feature film, providing a reliable skeleton that writers can build on, subvert, or disguise.
Blake Snyder
Save the Cat breaks a 110-page screenplay into 15 specific beats, each with a target page number. It is the most prescriptive mainstream structure framework, giving writers a precise roadmap from Opening Image to Final Image. The name comes from Snyder's advice that your protagonist should do something likable early — like saving a cat — to win the audience.
Joseph Campbell (The Hero with a Thousand Faces), adapted for screenwriters by Christopher Vogler (The Writer's Journey)
The Hero's Journey maps a protagonist's transformation through 12 mythological stages, from the Ordinary World through trials, death-and-rebirth, and return. Originally a comparative mythology framework, Christopher Vogler adapted it into a practical screenwriting tool. It emphasizes psychological transformation and archetypal character roles over mechanical plot points.
Dan Harmon
Dan Harmon's Story Circle distills the Hero's Journey into 8 simple steps arranged in a circle: You, Need, Go, Search, Find, Take, Return, Change. Designed for television, it gives writers a repeatable engine for episodic storytelling where characters must transform within 22 or 44 minutes. Each step maps to a position on the circle, creating a visual rhythm.

The Sequence Method divides a feature screenplay into eight sequences of approximately 12-15 pages each. Each sequence functions as a mini three-act structure with its own setup, escalation, and resolution. The framework bridges the gap between broad three-act structure and individual scene work, giving writers a manageable middle layer of story organization.
Chris Soth
The Mini-Movie Method structures a feature screenplay as eight self-contained 'mini-movies' of roughly 12-15 minutes each. Each mini-movie has its own protagonist goal, antagonistic force, and climactic moment. The framework prioritizes audience engagement by ensuring no segment of the film goes more than 15 minutes without delivering a complete, satisfying dramatic unit.
