"When it comes to story structure, I've always relied on my gut. But Melvyn's 19 Sequence Model shows that almost all films follow the same pattern, whether it's science fiction, drama or comedy. His 19 Sequence theory helped me unlock the Act 3 of a story I had been unable to resolve for months. Many thanks!"
Ronald Shusett - Producer/Co-writer "Alien" and "Total Recall"; Executive Producer "Minority Report".


The 19-Sequence Model of Screenplay Structure

Screenplays are made from Sequences and their composite Scenes. Understanding these fundamental building blocks of Screenplay Structure is a critical element in writing a successful script. Our 19-Sequence Model of Screenplay Structure (published in the Journal of Screenwriting in 2012) shows how Sequences are distributed within the 3-Act Model.


So, use the 19-Sequence Model to accelerate your creative scriptwriting. Learn the unlocked secrets of what happens when in key movie genres and plot types. This 19-Sequence Formula sharpens the pace of your story and plot, and correctly locates key plot points to engage your audience and fulfil genre expectations. Improve your storytelling and marketability!

Through a detailed analysis of 132 Classic and Contemporary screenplays across a broad spectrum of plot types and genres from 1941-Present, ScreenWriting Science identified a fundamental Scene-Sequence structure of successful feature films - the 19-Sequence Model. This structure, plus each film's story events and plot points, are captured in the Screenplay Sequence-Scene Structure Summaries. As Ron Shusett observes, the "...19 Sequence Model shows that almost all films follow the same pattern, whether it's science fiction, drama or comedy...". The Summaries are 8-23 page PDF documents that show you how each screenplay uses the Sequence-Scene organization to present specific plot points to advance the story and create emotional impact.


Sequences are the real way screenwriters organize plot and story into manageable units. Sequences are the managable units that make plot and story construction easier. You can use the Screenplay Summaries as Templates and Event Road Maps guide your own writing, or simply enjoy reading to appreciate the construction of the story. So, choose movies that are similar to the one you are interested in using as a model in your own writing. You can also look at screenplays that cover your sub-plot or utilize techniques, such as flashbacks and foreshadowing. The Summaries make it easier to identify key event milestones, plot point types, understand pacing, when to include location changes, and position respite and exposition scenes.

An ideal Coming-of-Age model . Principle emotional events occur in Acts I and II, with a short Act III that quickly resolves the subsequent relationship of the four boys. Compare with Breaking Away

Citizen Kane

Citizen Kane is a lesson in Flashback structure and how to organize a biography. Follow Kane: 'Rosebud' simply serves 'Bookend' and McGuffan purposes.

A Few Good Men

The Screenplay Structure is organized around Kaffee's experiences. Other than the flashback of Colonel Jessep's order of the 'Code Red', essentially everything is from Kaffee's perspective.


As extension of the classic: Alien. Aliens combines Chase-Escape with a Rescue plot, which extends the emotional impact beyond 'Fear'. Incorporation of 'Compassion' and 'Self-Sacrifice' magnify the humanity of the characters.  



Each Sequence takes us through specific stages in Mark Renton's journey from addiction to sobriety and creates an Act III that gives the critical climax accomplishment.


The Day of the Jackal

The Structure resonates between the Jackal's progress to taking the explosive bullet shot at de Gaule and Inspector Lebec's pursuit of the Jackal. Each Sequence make a point - then moves on.
