Turn an Agency Script Into a Treatment Story the Reader Can See and Hear

A treatment story is not the agency script wearing nicer clothes. It is the point where sequence becomes experience.

The script tells you that a person enters a café, recognizes an old friend, and puts a reusable cup on the table. The treatment decides what the viewer notices first. Does recognition arrive in a face, a sound, a familiar gesture? Do we see the friend before the character does, or discover them together? Does the cup interrupt the moment, complete it, or simply remain a required object in the scene?

Keep the agreed actions and words recognizable. Expand the places where direction changes their effect. Compress the connections the reader can already follow. And when you add a beat rather than interpret one, call it a proposal.

The treatment’s job is to reveal the film inside the script—not quietly replace the script with another one.

Mark what is fixed before you begin to move it

Read the script once for story. Read it again for authority.

Mark required actions, approved dialogue or voiceover, product appearances, supers, claims, and the order of any beats whose order matters. Then mark what the script leaves open: staging, performance, point of attention, sound, withholding, transitions, and the physical relationship between people and objects.

The distinction will not always be clean. A performance choice can imply new history. A pause can change a line from sincere to evasive. Moving a product beat earlier may alter what the scene appears to be about. That is why the work needs judgment, not merely color.

Agency-side and director-side accounts describe the same tension from different positions. In an interview about selecting directors, TBWA\Hunt Lascaris ECD Steph van Niekerk says directors should not simply return what the agency supplied; she wants a strong point of view that brings the idea to life. She also stresses that signed-off scripts contain things that are movable and things that are not. Commercial director Ryan Booth describes receiving the agency’s script, then writing how he would make the commercial, what it would feel like, and why—sometimes with a proposed rewrite or personal spin. These are individual accounts, not universal permission to rewrite.[^1][^2]

Start, then, with two columns in your notes:

• Fixed: what the treatment must preserve or explicitly seek permission to change.
• Open to direction: what the treatment is expected to interpret.

That small separation prevents vivid prose from laundering a material change.

Follow the viewer, not the document

A script is built for many kinds of readers. Its economy is a strength. But a treatment passage has a different question to answer: what will this commercial be like to encounter?

Write in the order of attention. At each beat, ask:

• What can the viewer see or hear now?
• What do they understand because of it?
• What remains withheld?
• What changes the meaning of the next moment?

This does not require explaining every cut. It requires causal and spatial clarity. If a sound pulls someone’s attention across the room, place the sound before the look. If the audience recognizes a person before the protagonist does, say so; suspense and shared discovery are different experiences. If a character knows something the film has no way to communicate, do not place that private knowledge in the treatment as though it will appear on screen.

“She remembers all their mornings together” may be emotionally accurate in the writer’s head. Unless the proposed film gives us behavior, image, sound, dialogue, or context that carries the memory, it is not yet an experience the viewer can have.

Spend detail where direction changes the effect

Not every action deserves equal prose.

“He crosses the café” may be enough if crossing only connects entrance and table. Recognition, however, may need room because performance and sound determine whether it feels immediate, awkward, comic, or tender. The reusable cup may need one exact placement if its arrival shifts the scene or satisfies a mandatory product beat.

Expand the hinge. Let the door remain a door.

This is where treatment writing escapes both common failures: the gray paraphrase that merely repeats every script beat, and the purple expansion that gives every hand movement a metaphor. Selective detail tells the reader where the directing lives.

Sound belongs here too. A later “Sound” chapter can describe the larger approach, but the story passage should include any sound that changes attention, recognition, timing, or meaning. Silence is not a general mood when it causes the room to feel different. A rhythm is not decoration when it lets one person find another.

An invented script, first flattened and then directed

The following café commercial is entirely fictional. It is not an agency script, client project, approved claim, or account of a produced film.

Supplied script

INT. CAFÉ — MORNING

ALEX enters the busy café carrying a reusable cup.

Across the room, ALEX recognizes an old friend, SAM, seated at a table.

ALEX joins SAM and places the reusable cup on the table. They smile.

VOICEOVER: Some things are worth coming back to.

Product end card.

The script fixes the café arrival, the carried cup, recognition of an old friend, the meeting at the table, the cup placement, the smile, the exact closing line, and the end card. It does not tell us how recognition unfolds.

A faithful paraphrase that adds almost nothing

Alex enters a bustling café holding a reusable cup. Looking across the room, Alex spots an old friend, Sam. Alex walks over, puts the cup down, and they share a warm smile as we hear, “Some things are worth coming back to.” We end on the product.

Nothing material has been lost. Nothing directorial has become clearer either. “Bustling” and “warm” are conclusions looking for evidence.

A treatment passage that creates an experience

Morning has already filled the café with small collisions: the steam wand’s sharp breath, cups settling into saucers, chair legs nudged across tile. Alex enters with the reusable cup held against their coat and searches for a free table.

Beneath the room’s loose clatter, three soft taps land on wood. A pause. Then the same three again.

Alex stops. The sound has reached them before the face has. Across the café, a hand repeats the rhythm at the edge of a table. We finally find Sam behind it, waiting to see if an old habit still works.

Recognition arrives slowly across Alex’s face, almost disbelieving before it becomes a smile. The rest of the walk is simple. Alex reaches the table and places the reusable cup in the open space between them. Sam’s answering smile completes the reunion.

Over that image, unchanged: “Some things are worth coming back to.” Then the supplied product end card.

The passage preserves every declared requirement. Its main addition is a proposed tapping rhythm that makes recognition audible and gradual. It also withholds Sam’s face until Alex has responded to the sound, letting the viewer discover the friend through the same cue.

That rhythm is not merely prettier description. It implies a familiar habit shared by these old friends. Even though the script already establishes their history, this particular evidence of it is new and should be identified as a directorial proposal rather than smuggled in as fact.

Separate interpretation from a changed story beat

Now consider an optional version:

As Alex arrives, Sam stands. Without speaking, they exchange places—Sam taking the chair Alex used to prefer, Alex settling into Sam’s. Only then does Alex place the cup between them.

This may be charming. It may also change the scene. The supplied script says Alex joins Sam; it does not establish a remembered seating ritual or require Sam to move. The exchange adds action, backstory, timing, and a new piece of blocking around the product beat.

Label it accordingly:

Proposed new beat for approval: The friends exchange places before the cup is set down. This gives their history a physical ritual and delays the product placement by one action. If not adopted, the gradual tapping recognition works without it.

The label does not weaken the idea. It lets the team judge the actual idea.

Trace the passage back to its source

Before calling the story section finished, compare it beat by beat with the script:

This audit catches two opposite errors. Expansion can hide a rewrite; compression can drop a requirement. Both can produce a beautiful paragraph that is wrong.

Let the prose point to the directing

The finished story passage should give the reader a film they can follow with their senses and question with precision. They should know what becomes apparent, when it becomes apparent, and why a particular sound, look, or action matters. They should also be able to find the original script inside it.

You do not need to inflate every beat. Give space to the moments whose execution changes the effect. Let connective action move. Keep sound beside the action it changes. Preserve approved words. Mark the new beat.

The result is not a duplicate script and not a concealed rewrite. It is a directorial proposition with its fingerprints visible.

Frequently asked questions

What is the difference between a treatment story and a paraphrased agency script?

A paraphrase repeats script beats in different words. A treatment story decides what the viewer notices first and how recognition, sound, or timing unfolds. It interprets sequence rather than merely restating it.

Before expanding a script, what should be marked as fixed?

Required actions, approved dialogue or voiceover, product appearances, supers, claims, and any beat order that matters. Staging, performance, point of attention, sound, withholding, transitions, and physical relationships are usually open to direction.

Why should sound appear in the story passage rather than only in a later sound chapter?

When a sound changes attention, recognition, timing, or meaning, it belongs beside the action it alters. A tapping rhythm, for instance, can make recognition audible and gradual.

How should a treatment handle an added beat like friends exchanging places?

Label it as a proposed new beat for approval, because the source script may not establish that ritual and it adds action, backstory, timing, and blocking around the product beat. The label lets the team judge the actual idea.

What two opposite errors can a beat-by-beat audit catch?

Expansion can hide a rewrite, and compression can drop a required element. Both can yield a beautiful paragraph that is wrong.
