Come scrivere la scaletta di una sceneggiatura

A screenplay is a blueprint. Unlike a novel, which is the final product a reader consumes, a screenplay is an intermediate document -- a set of instructions for directors, actors, and editors to interpret. This changes everything about how you outline it. A screenplay outline is not about beautiful prose or deep interiority. It is about structure, pacing, and visual storytelling. It is about knowing what happens in every scene and why it matters, so that when you sit down to write FADE IN, you can focus on execution rather than invention.

This guide covers the process of outlining a feature-length screenplay from the ground up: starting with the logline, building through the beat sheet, and arriving at a scene-by-scene plan that gives you everything you need to write a strong first draft.

Start With the Logline

Before you outline a single scene, you need a logline. A logline is a one- or two-sentence summary of your screenplay that captures the protagonist, the central conflict, and the stakes. It is the DNA of your story, and if you cannot write a clear logline, you are not ready to outline.

A strong logline has four elements:

• A protagonist with a defining trait: Not a name -- a description that tells us something about who this person is. "An agoraphobic forensic accountant" is better than "John."
• An inciting event: What disrupts the protagonist's world and sets the story in motion?
• A goal: What does the protagonist want to achieve?
• Stakes: What happens if they fail?

Examples:

• "When a burned-out astronaut discovers her daughter's Mars colony has lost contact with Earth, she must lead a rescue mission through uncharted space before the colony's oxygen runs out." (Protagonist with trait, inciting event, goal, stakes.)
• "A small-town sheriff with a secret past must protect his community from a cartel enforcer who knows who he really is." (Same structure, different genre.)

The logline is not a marketing tool at this stage. It is a structural tool. It forces you to identify the core of your story before you start layering on complexity. Write it, refine it, and pin it above your desk. Every scene you outline should serve this logline. If a scene does not connect to the protagonist's goal or the central conflict, it probably does not belong in the screenplay.

The Beat Sheet: Your Structural Backbone

A beat sheet is a list of the major story events (beats) that define the screenplay's structure. Think of it as the skeleton -- the bones that everything else hangs on. There are several beat sheet models, but the one most widely used in the film industry derives from Blake Snyder's Save the Cat!, adapted from Syd Field's three-act paradigm.

Here are the beats for a standard feature film (90-120 pages):

Act I (pages 1-25): Setup

Opening Image (p. 1): The first thing the audience sees. It should establish tone and give a visual snapshot of the protagonist's world before the story changes it. Think of the opening shot of The Social Network -- Zuckerberg at a bar, talking too fast, already alienating the person in front of him. In one scene, you know who this person is.

Setup (pp. 1-10): Establish the protagonist's world, their daily life, their relationships, and the thing that is not working. The setup does not need to be a literal "day in the life." It needs to show the audience what is at stake if the protagonist changes -- and what is at stake if they do not.

Theme Stated (p. 5): Someone -- not necessarily the protagonist -- states the movie's thematic question, usually in dialogue. The protagonist does not understand its significance yet. In Groundhog Day, Rita tells Phil he is "the most self-centered person she has ever met." That is the theme. The movie is about learning to stop being self-centered. Phil does not get it yet. The audience might not either. But on a rewatch, the line glows.

Catalyst (p. 12): The inciting incident. The event that disrupts the status quo and sets the story in motion. It should be external, concrete, and impossible to ignore. A letter arrives. A body is found. The aliens land. The protagonist's spouse says "I want a divorce." The catalyst is not a gradual development. It is a specific moment that changes everything.

Debate (pp. 12-25): The protagonist resists the call. They debate whether to engage with the new situation. This section builds tension and raises the question: will they or won't they? The debate should not be passive. The protagonist should be actively weighing options, seeking advice, trying to solve the problem without committing to the journey.

Break into Two (p. 25): The protagonist makes a choice. They commit to the journey, enter the new world of Act II. This must be an active decision, not something that happens to them. The protagonist's agency is what distinguishes this beat from the catalyst. The catalyst is imposed. The break into two is chosen.

Act II (pages 25-75): Confrontation

B Story (p. 30): A secondary storyline begins, usually a relationship (romantic, friendship, or mentor-student) that carries the theme. The B story gives the protagonist someone to talk to about what they are going through, which is crucial in a visual medium where internal states must be externalized.

Fun and Games (pp. 30-55): The promise of the premise. This is the reason the audience bought the ticket. In a heist movie, this is the planning and the heist itself. In a rom-com, this is the couple falling in love through a series of charming encounters. In an action movie, this is the action. This section should be the most entertaining part of the screenplay, the part that delivers on the concept.

Midpoint (p. 55): A major event that raises the stakes and shifts the story's direction. Either a false victory (things seem to be going well, but danger is approaching) or a false defeat (things seem hopeless, but the protagonist has not yet found their real strength). The midpoint should change the protagonist's understanding of their situation. New information is revealed. The rules change. The antagonist shows their true strength.

Bad Guys Close In (pp. 55-75): The antagonistic forces tighten their grip. The protagonist's plans start to fail. Internal doubts surface. Allies waver or betray. This section is about escalating pressure -- external obstacles become harder and internal flaws become more costly. The protagonist's old way of doing things stops working.

All Is Lost (p. 75): The lowest point. The protagonist loses something important -- a mentor dies, a plan fails catastrophically, a relationship breaks. There should be a "whiff of death," literally or metaphorically. The audience should genuinely wonder if the protagonist can recover from this.

Act III (pages 75-110): Resolution

Dark Night of the Soul (pp. 75-85): The emotional aftermath of the All Is Lost moment. The protagonist processes their failure, grief, or despair. This is the quiet before the storm, and it is where many screenwriters rush. Do not rush it. The audience needs to feel the weight of the loss before the protagonist rises from it.

Break into Three (p. 85): The protagonist discovers the solution, usually by synthesizing lessons from the A story (the external plot) and the B story (the thematic relationship). This is the "aha" moment -- the insight that the protagonist could not have reached without going through everything in Acts I and II.

Finale (pp. 85-110): The protagonist executes the new plan, confronts the antagonist, and resolves the central conflict. The finale should test the protagonist's growth. The solution that works should be one that requires the protagonist to have changed -- the person they were at the beginning of the movie could not have done this.

Final Image (p. 110): The mirror of the opening image. It shows how the protagonist's world has changed. The contrast between the opening image and the final image is the visual thesis statement of the movie.

From Beats to Scene Cards

Once you have your beat sheet, the next step is to break each beat into individual scenes. This is where the outline becomes granular and where most of the creative heavy lifting happens.

What a Scene Card Contains

For each scene, write an index card (physical or digital) with:

• Scene heading: INT./EXT., location, time of day
• Characters present: Who is in the scene?
• What happens: One to three sentences describing the action
• Purpose: Why this scene exists -- what it accomplishes for the story (advances plot, reveals character, delivers information, builds tension)
• Emotional shift: How does the scene's emotional state change from beginning to end? A scene where nothing changes emotionally is a scene that can probably be cut.

A standard feature film has 40-60 scenes. Each scene runs roughly two to three pages. When you lay all your cards out in order, you should be able to read through them and feel the movie -- the rising tension, the midpoint shift, the low point, the climax. If any section feels slack or repetitive, you can see it at the card level and fix it before you have written a word of actual screenplay.

The 40-Card Method

A practical approach: start with 40 blank cards. Assign roughly 10 to Act I, 20 to Act II (10 for the first half, 10 for the second), and 10 to Act III. Place your beat sheet events on the appropriate cards. Then fill in the remaining cards with the scenes that connect the beats. Each card should represent a single scene -- one location, one continuous sequence of action.

This method makes pacing visible. If you have 15 cards in Act I and only 5 in Act III, your ending is going to feel rushed. If the first half of Act II has 12 cards and the second half has 4, you have a pacing problem. Rebalance before you start writing.

Pacing: The Invisible Craft

Pacing in screenwriting is about managing the audience's experience of time and tension. Too fast and they feel rushed, confused, or emotionally uninvested. Too slow and they check their phones.

Scene Length Variation

Vary your scene lengths deliberately. A series of short, clipped scenes creates urgency and momentum. Longer scenes allow for character development and emotional depth. The best screenplays alternate between the two, creating a rhythm that sustains the audience's attention.

A common pacing mistake is writing every scene at the same length. If every scene runs two-and-a-half pages, the screenplay develops a monotonous rhythm that puts the audience to sleep even if the content is strong. Let some scenes breathe. Let others hit hard and fast.

The Sequence Approach

Many screenwriters think in sequences rather than individual scenes. A sequence is a group of scenes (usually three to seven) that builds toward a mini-climax. A feature film typically has eight sequences, roughly two per act (with Act II split into halves). Each sequence has its own setup, escalation, and payoff.

Thinking in sequences helps with the "sagging middle" problem. Instead of trying to sustain tension across a 50-page Act II, you are sustaining it across a 12-page sequence, then resetting and building again. The audience gets regular payoffs that keep them engaged while the larger structure builds toward the act breaks.

Outline vs. Treatment

A common source of confusion: an outline and a treatment are different documents.

An outline is a structural document for the writer. It can be in any format -- bullet points, index cards, a spreadsheet, a whiteboard covered in sticky notes. Its purpose is to help you plan the screenplay. No one but you needs to see it.

A treatment is a narrative document for other people -- producers, agents, development executives. It is written in prose, present tense, and reads like a short story version of the movie. A treatment is typically 5-15 pages and tells the complete story, including the ending. Treatments are sales documents; outlines are planning documents.

When outlining for yourself, use whatever format works for you. When writing a treatment for industry professionals, follow the conventions: present tense, third person, prose paragraphs, no scene headings, no dialogue (or minimal dialogue for key lines), and always reveal the ending.

Common Screenplay Outlining Mistakes

Starting Too Late

The most common structural problem in amateur screenplays is a late start. The story does not begin until page 15 or 20, because the writer spent the first act on backstory, atmosphere, and character setup. In a feature film, the catalyst should land by page 12 at the latest. If the audience does not know what the movie is about by the end of the first act, you have lost them.

In your outline, make sure the catalyst is early and unmistakable. Then make sure the break into Act II is a clear, active choice by the protagonist. If these two beats are in the right places, the first act will work.

Passive Protagonists

In a novel, a character can be interesting while doing relatively little -- the narration provides interiority that sustains engagement. In a screenplay, you do not have that luxury. The audience can only see and hear. If the protagonist is not making choices, taking actions, and driving the story forward, they are boring -- no matter how rich their inner life might be.

Check every scene in your outline: is the protagonist making a decision or taking an action? If not, can you restructure the scene so they are? A protagonist who reacts is less engaging than one who acts.

Neglecting the Antagonist

Your antagonist needs their own plan. A common weakness in outlines is an antagonist who exists only to oppose the protagonist without having their own goals, motivations, and strategy. The best movie antagonists are protagonists of their own story -- they have a plan, and the protagonist is the obstacle. When both sides are actively pursuing their goals, the collision generates genuine dramatic tension.

Scenes That Do Only One Thing

Every scene in a screenplay should do at least two things. It should advance the plot AND reveal character. Or build tension AND deliver information. Or develop a relationship AND set up a future payoff. Scenes that accomplish only one purpose are candidates for combination or deletion. In a 110-page screenplay, you do not have room for single-purpose scenes.

Ignoring Visual Storytelling

Film is a visual medium. Your outline should be thinking in images, not just in plot points. What does each scene look like? What is the visual contrast between the beginning and the end of the movie? Are there visual motifs that recur and evolve? The opening image and final image beats are not just structural markers -- they are visual bookends that give the movie coherence.

When writing scene cards, include a brief note about the visual quality of the scene. Not camera directions (that is the director's job), but the visual experience. "Cramped, dim apartment" tells you something different from "vast, sunlit desert." Both create mood. Both communicate without dialogue.

Putting It All Together

Here is the process, condensed:

1. Write the logline. Protagonist, inciting event, goal, stakes. One to two sentences.
2. Identify the ending. How does the central conflict resolve? What has changed?
3. Build the beat sheet. Place the major structural beats on a timeline. Make sure the catalyst, midpoint, All Is Lost, and climax are clear and compelling.
4. Break into sequences. Divide the beat sheet into eight sequences, each with a mini-arc.
5. Write scene cards. 40-60 cards, each with heading, characters, action, purpose, and emotional shift.
6. Pressure-test. Read through the cards. Check pacing, protagonist agency, escalation, and the balance between acts. Fix structural problems now, not in the draft.
7. Write. You know what every scene needs to accomplish. Focus your creative energy on dialogue, visual storytelling, and the moments that make the audience feel something.

An outline is not a finished screenplay. It is a foundation. The best scenes in your screenplay will surprise you -- a line of dialogue that comes out of nowhere, a visual moment that you did not plan but that captures the movie's soul. The outline does not prevent those surprises. It creates the conditions for them. When you know where you are going, you are free to explore the territory along the way.
