Scene Description

Also called: action lines, action description, scene action

Scene description, also called action lines, is the prose under a scene heading that tells the reader what we see and hear. It is written in present tense, in short visual paragraphs that read like shots, so a director, a cinematographer and an actor can all picture the same moment from the page.

Video script

Sir? My line says Yaro has never forgiven Portugal. Which eyebrow is that? This one?

Playback. We got a man. Scene description, or action lines, is the prose under a heading, in present tense: only what we see and hear.

One test per sentence: can a camera or a microphone record it? Thoughts, backstory, Portugal: no.

This man could be remembering the day his brother left. Or Portugal. The camera got a man and a window.

So find the behavior. A postcard from Lisbon. Sunglasses indoors. He won't write back. Never forgiven.

New speaking character? Name in capitals, an age range, one or two visible details. Square head, glaring at a custard tart.

Precise verbs. Walks is neutral. Shoulders past is a performance. Limps too, but this Limping Man is sitting down.

One paragraph, one shot. He passes a green hatchback. New paragraph: a postcard on the dashboard. A wide and an insert, neither word on the page.

So never write close on his hands, or the camera pans left. That's the director's job, and now I'm talking to nobody.

Paste each paragraph on a FlashBoards board, generate a frame. Weak description comes back generic. Orange sodium light gets a ferry. Portugal gets a man.

You're thinking about scrolling down. Camera got someone staring at a phone. Do the behavior. Scroll down.

What it does: Turns a location and a time of day into images, sounds and behavior the reader can see.
Use it when: Every scene: anything that is not dialogue, a heading or a transition is scene description.
Watch out: Unfilmable lines (thoughts, backstory) and camera directions that do the director's job.
Try this prompt: Film still, car deck of a night ferry, rows of parked cars under orange sodium light, a woman in a paramedic's jacket checking license plates

What is a scene description in a screenplay?

Every scene in a screenplay is built from a few elements: the scene heading, the scene description, character names, dialogue, parentheticals and transitions. The scene description is everything that happens on screen that nobody says out loud: the room, the light, a gesture, a sound, a door that won't open.

``` INT. NIGHT FERRY - CAR DECK - NIGHT

Rows of parked cars under orange sodium light. Engines tick as they cool. The whole deck sways.

NADIA (40s, grey braids, paramedic's jacket) walks between the cars, checking each plate against a scrap of paper.

She stops at a green hatchback. A child's shoe sits on the dashboard. ```

It runs the full width of the page, always in present tense, because the reader should experience the scene as it happens. In screenwriting software it is the "Action" element.

What belongs in action lines, and what doesn't

The test for every sentence is simple: can a camera or a microphone record it?

Belongs: what the set looks like, the light, what characters do, props that matter, sounds that matter, and a character's first appearance. New speaking characters get their name in CAPITALS once, with an age range and one or two visible details that say who they are: That tells wardrobe and casting more than a line about her past.

Doesn't belong: thoughts, memories and backstory the audience cannot see (She remembers the day her brother left). Either find the behavior that shows it or cut it; that is where subtext lives.

Key sounds and props are sometimes typed in caps (a PHONE BUZZES) so they get caught in the breakdown. Use this lightly.

How to write action lines that read like shots

Keep paragraphs to one to four lines. Each paragraph is one image or one beat. Dense blocks get skimmed.
One paragraph, one shot. A new paragraph implies a new angle. She stops at a green hatchback. / A child's shoe sits on the dashboard. is a wide and an insert without either word on the page.
Use precise verbs. Walks is neutral; limps and shoulders past are performances.
Be specific where it counts. A car is nothing; a green hatchback with a cracked windshield is a prop list and an image.
Write in order. Describe things in the order the audience sees them.
Match rhythm to pace. Fragments for tension (Locked. She tries the next one.), longer sentences for calm.

Should you write camera directions in scene description?

In a spec script, mostly no. Lines like CLOSE ON her hands or the camera pans left take choices away from the director and slow the read. When one detail truly has to be isolated, ANGLE ON or a single we see is accepted, but avoid more than a handful per script.

Camera language becomes normal later, in the shooting script, where the director and cinematographer add scene numbers and shot notes. Some films are exceptions by design: 1917 (2019) plays as one continuous shot, broken only by a single cut to black, so its script had to describe the action as unbroken movement, with almost no cuts to hide behind.

Scene description example: before and after

Before:

`` We see Nadia, an exhausted paramedic who has been searching for her nephew for three days, walking slowly through the dark car deck, feeling desperate. ``

After:

``` NADIA (40s, grey braids, paramedic's jacket) moves between the parked cars, checking each plate against a scrap of paper. Her hand shakes.

A green hatchback. A child's shoe on the dashboard.

She tries the door. Locked. ```

The rewrite drops we see, the backstory and the adjectives about feelings. The shaking hand carries the exhaustion; the shoe carries the missing child. One long sentence became three shots.

From action lines to storyboard and shot list

Each paragraph becomes a candidate panel in the storyboard and a line in the shot list; a vague paragraph produces a vague frame. That makes action lines a useful test of visual storytelling: if you cannot draw a paragraph, the audience cannot see it.

In FlashBoards you can paste each paragraph onto the board as a note, generate a frame from it and set the frames in a row under the scene heading. Weak description shows up at once as a generic image.

FAQ

5 questions

What is scene description in a screenplay?

Scene description is the prose under each scene heading that describes what the audience sees and hears: the setting, the light, what characters do, important props and sounds. It is written in present tense, in short paragraphs, and is also called action or action lines.

How long should action lines be?

Most working writers keep each paragraph to one to four lines and give every new image or beat its own paragraph. Dense blocks of five or more lines get skimmed, and since a page is roughly a minute of screen time, overlong description misrepresents the running time.

Are action lines written in present tense?

Yes. Scene description is always in present tense, because the reader should experience events as they happen on screen: She opens the door, not She opened the door. She runs also reads faster than She is running.

Should I use "we see" in scene description?

Sparingly. We see is a mild camera direction and usually adds nothing: We see a car pull up reads better as A car pulls up. It is acceptable when the audience must notice something a character doesn't.

How do you introduce a character in action lines?

The first time a speaking character appears, write the name in capitals, followed by an age range in parentheses and one or two visible details: NADIA (40s, grey braids, paramedic's jacket). After that the name is in normal case.
