Screenplay by Syd Field - Review

Overview

Screenplay: The Foundations of Screenwriting was first published in 1979 and has been continuously in print ever since. Syd Field didn't invent three-act structure (Aristotle got there first) but he was the first person to codify it specifically for screenwriters in a way that was clear, practical, and immediately applicable. For better or worse, Field's paradigm became the default structural framework for the American film industry.

Field worked as a story analyst and head of the story department at Cinemobile Systems, where he read thousands of screenplays. That experience gave him an empirical understanding of what separated scripts that worked from scripts that didn't. His book distills that understanding into a structural model so simple it can be drawn on a napkin: three acts, two plot points, and a midpoint.

The book's influence is difficult to overstate. Every screenwriting book published after 1979 is, in some sense, a response to Field, either building on his model, refining it, or arguing against it. Understanding the paradigm is a prerequisite for understanding the conversation about screenplay structure.

The Three-Act Paradigm

Field's model divides a screenplay into three acts with specific proportions. For a standard 120-page screenplay:

Act I: Setup (pages 1-30) - Establishes the protagonist, the dramatic situation, and the world of the story. The audience learns who the main character is, what they want, and what's at stake. Act I ends with Plot Point I, an event that spins the story in a new direction and propels it into Act II.

Act II: Confrontation (pages 30-90) - The longest act, where the protagonist pursues their goal and encounters escalating obstacles. Field acknowledges that Act II is where most screenwriters struggle, and in later editions he added the concept of a Midpoint to help divide this sprawling section into two more manageable halves. Act II ends with Plot Point II, which sends the story into its final act.

Act III: Resolution (pages 90-120) - The climax and its aftermath. The central dramatic question is answered. The protagonist either achieves their goal or doesn't, and the consequences of the story play out.

Plot Points

The two plot points are the structural pillars of Field's paradigm. He defines a plot point as "an incident or event that hooks into the action and spins it around in another direction." They are the connective tissue between acts, and getting them right is, in Field's view, the single most important structural task a screenwriter faces.

Plot Point I (end of Act I, around page 25-27) - The event that launches the main story. In Star Wars, it's Luke discovering that his aunt and uncle have been killed and deciding to join Obi-Wan. In The Shawshank Redemption, it's Andy Dufresne's conviction and arrival at the prison. Before this point, we're in the setup. After it, we're in the story.

The Midpoint (around page 60) - Added in later editions, this is the event that divides Act II into two halves. It raises the stakes, reveals new information, or shifts the protagonist's approach to the problem. Field initially didn't include the midpoint, which is why many critics accused his model of leaving writers stranded in the desert of Act II. The midpoint was his corrective.

Plot Point II (end of Act II, around page 85-90) - The event that triggers the climax. It often involves a revelation, a decision, or a reversal that makes the final confrontation inevitable. In Chinatown, it's Jake discovering the truth about Evelyn's relationship with her father. In Thelma & Louise, it's the decision to keep driving.

Character Development

Field's approach to character is straightforward: define the character's dramatic need (what they want to achieve during the screenplay), their point of view (how they see the world), and their attitude (how they express that point of view). He also introduces character biography - writing a detailed backstory for your protagonist to understand what drives them.

He distinguishes between what a character wants (their external goal) and what they need (their internal transformation). A strong screenplay, in Field's view, puts these in tension: the character pursues what they want and, in the process, discovers what they need.

The character development material is less innovative than the structural model. Field covers the basics competently but without the depth that McKee brings to the subject. Where McKee explores the philosophical implications of character under pressure, Field gives you practical exercises and moves on.

Strengths

The book's defining strength is simplicity. Field's paradigm is easy to understand, easy to remember, and easy to apply. You can explain three-act structure to someone in five minutes and they'll have a workable framework for thinking about story. There's enormous value in that clarity, especially for beginners.

Field is also an effective teacher in prose. The book is written in plain, conversational English with plenty of film examples. He walks through entire screenplays (Chinatown and Annie Hall are recurring references) and shows exactly how each structural element operates. You can read the book in a weekend and start applying it to your own work immediately.

The paradigm's simplicity also makes it an excellent diagnostic tool. If a script isn't working, you can check: Is there a clear inciting incident? Do the plot points actually turn the story? Is Act II holding together? These are basic questions, but they catch the most common structural problems.

Criticisms

The most persistent criticism of Screenplay is that the paradigm is too rigid. Three acts, two plot points, specific page ranges - it can feel like a mold you pour your story into rather than a framework you build from. Writers working in genres that resist clean three-act division (episodic narratives, ensemble pieces, non-linear stories) often find the paradigm unhelpful or actively constraining.

Field's model also struggles with the middle of the screenplay. Act II is sixty pages long and, even with the midpoint added in later editions, the book provides relatively little guidance for what happens between Plot Point I and Plot Point II. Snyder's Beat Sheet and Truby's twenty-two steps were both, in part, responses to this gap. Field tells you where Act II starts and ends but doesn't give you much to work with in between.

Some writers also find the film examples dated. Chinatown, Annie Hall, and The Shawshank Redemption are all great films, but a book aimed at beginners would benefit from more contemporary examples. Later editions added some, but the core references remain rooted in the 1970s and 1980s.

Finally, the character development sections feel thin compared to the structural analysis. Field defines character primarily through external goals and backstory, with less attention to the internal contradictions and moral complexity that make characters truly compelling. For deeper character work, you'll need to look elsewhere (McKee or Truby, for instance).

Who Should Read This

Screenplay is the ideal first book for anyone learning screenwriting. It establishes the structural vocabulary you'll encounter everywhere else (three acts, plot points, inciting incidents, dramatic need) and it does so with a clarity that no subsequent book has quite matched.

If you've already read Save the Cat! or McKee's Story, you may not need this book. Those authors cover similar ground with more detail. But if you haven't read any screenwriting book, start here. The paradigm is the foundation on which everything else is built, and understanding it, even if you eventually outgrow it, is important.
