Scene Headings, Action, and Dialogue: A First Guide to Reading a Screenplay
Scene Headings, Action, and Dialogue: A First Guide to Reading a Screenplay
Read a screenplay by separating where the scene happens, what happens within it, and what somebody says. Before turning the material into a pitch, be able to retell a short passage without giving one person's action to another, making an unseen speaker visible, or adding a motive the page has not established.
You do not need to memorize every formatting term to begin. You need to recognize what each part of the page is asking you to imagine. This guide uses one original fictional passage throughout. It is a reading exercise, not a template for judging whether someone else's screenplay is correctly formatted.
Locate the scene, then follow the action
Here is the passage. Its spacing is simplified for reading on this page; it is not a production-formatted screenplay page.
INT. BUS GARAGE - NIGHT
ADA switches off the radio. A loose key rattles against its casing.
She pulls the roller door halfway down.
BEN (O.S.)
Leave it there.
Ada stops. Her hand stays on the door.
ADA
(toward the opening)
You're late.
EXT. BUS GARAGE - NIGHT
BEN stands outside the half-open door, holding a folded timetable. He checks the empty road before ducking underneath.
The first line is a scene heading. Here, INT. places us inside, BUS GARAGE identifies the location, and NIGHT supplies the time of day. The later EXT. heading moves the presented scene outside. These are the basic functions Final Draft describes for scene headings.[^elements]
For this passage, locate yourself inside the garage first. Ada is there. The radio, its casing, the key, and the door are part of the described activity. Do not begin outside simply because the final paragraph tells you where Ben has been standing.
That distinction matters to the sequence of discovery. The reader encounters Ben's voice before the passage presents him outside with the timetable. Retelling those facts in the wrong order can remove a deliberate uncertainty, even when every noun remains correct.
The headings do not say why Ben is late. Nor does changing from INT. to EXT. establish a jump to another night. The continued door opening and Ben's movement connect the two portions here. Use those details rather than inventing either a time jump or a precise number of elapsed seconds.
Notice which text is spoken
The descriptions of Ada switching off the radio and lowering the door are action. The names above the spoken lines are character cues, and the words beneath those cues are dialogue. A short instruction in parentheses beneath a cue is a parenthetical. In this passage it directs Ada's line toward the opening. Capital letters alone do not make words dialogue: action can also contain capitalized names or emphasized objects.[^elements]
Now read just the spoken exchange:
Ben: “Leave it there.”
Ada: “You're late.”
Ada does not announce that she is turning off the radio. Ben does not say that he has a timetable. Those things are supplied differently. The distinction is not cosmetic: it changes what information characters give each other and what the audience receives through the scene.
Ada's line tells us that she regards Ben as late. It does not tell us the scheduled arrival time, whether they made an agreement, or whether he accepts her description. “Ben has broken his promise” would require something more than the two words she says.
Likewise, “She is angry” is a possible reading, not the only faithful transcription of the passage. The line could be sharp, weary, relieved, or deliberately difficult to place. For a first factual retelling, keep the words and the observable response. You can discuss the interpretation separately, with the author or against the rest of the screenplay.
A useful reading note might therefore have two sentences:
Ada stops lowering the door when Ben asks her to leave it, then says he is late. Her response may suggest irritation, but this excerpt does not specify her delivery.
The first sentence records the scene. The second acknowledges a reading without promoting it to an established character fact.
Hear an unseen voice without inventing narration
O.S. means off screen. In the example, Ben is speaking within the immediate scene but is not yet presented visibly. V.O., voice over, can instead mark narration or other speech heard over the images. Final Draft's explanation distinguishes these functions and also notes variation in how writers label cases such as telephone dialogue. Read a notation together with its surrounding action rather than assuming one abbreviation settles every situation.[^voice]
Here the surrounding action is sufficient. Ada directs her answer toward the door opening; the next section places Ben just outside it. There is no phone, recording, flashback, or older Ben narrating his life. Adding any of those would change the material.
The absence of Ben from view also does not mean he is absent from the event. “Ada closes the garage alone, remembering Ben's voice” is not a compressed version of this passage. It is another scene.
To see the difference, consider an explicitly rewritten version:
Ada lowers the door until it meets the ground.
BEN (V.O.)
That was the last night she ever waited for me.
This is new fictional material, not information hidden in the original. It offers commentary about an event rather than Ben's immediate request to leave an opening. It also closes the door, changes the line, and introduces a claim about the future. Do not carry those changes back into your account of the first version.
Keep actions attached to the person who performs them
Try reconstructing the original without looking at it. Who switches off the radio? Who stops the door? Who holds the timetable? What happens between hearing Ben and seeing him?
A fluent but inaccurate retelling could be:
Ben switches off the garage radio and demands that Ada wait. Furious at his lateness, she slams the door, forcing him to find another entrance.
It sounds like a scene. It is not this scene. The first action belongs to Ada. Ben asks her to leave the door where it is; no demand to wait is written. She stops the door rather than slamming it. No second entrance appears. The adverb and emotional explanation have covered several factual substitutions.
Here is a faithful plain-language reconstruction:
Inside the bus garage at night, Ada turns off a radio and starts lowering the roller door. Ben, still unseen, asks her to leave it halfway down. She stops and tells him he is late. Outside, he checks the empty road with a folded timetable in his hand, then ducks under the door.
That paragraph preserves who does what and the order in which the passage reveals it. It does not claim that the key belongs to a bus or that the timetable proves Ben has missed one. Those are plausible associations, but the excerpt has not confirmed them.
Even the faithful reconstruction makes a selection. It omits the key's rattle and Ada's hand remaining on the door. That may be acceptable for a brief account of the event. It would not be acceptable if your purpose were to discuss the scene's sound or the physical hesitation in Ada's response. Accuracy includes choosing details that fit the question you are answering, not mechanically carrying every detail into every document.
Do not turn page organization into a shot list
When reading this excerpt for a pitch, preserve the reveal without claiming a camera plan. We hear Ben before seeing him; that order is in the passage. A close-up of Ada's hand, a tracking move along the shutter, and a shot of Ben's watch are not.
You might imagine those images while reading. Keep that imagination available as a proposal rather than disguising it as the writer's instruction. “The passage withholds Ben from view until the exterior section” describes the supplied sequence. “The camera tracks out through the door to reveal Ben” adds a particular execution.
The same care applies to the key's rattle. It is a stated sound. You do not need to decide that it signals danger, will become an important clue, or deserves a page of the deck before you have read further. Record it, notice whether it returns, and let the complete material establish its weight.
If a screenplay supplies a specific shot or transition, read that instruction. This example does not. Neither a new paragraph nor an emphasized word gives you permission to invent one and call it settled.
Carry the right uncertainty into the pitch work
Once you can reconstruct the passage, ask what you still need to know for the document you are making. A broad question such as “What is this scene about?” may invite a useful conversation, but it can also hide a small, answerable uncertainty.
For this excerpt, a sharper author question is:
When Ben checks the road, should a pitch reader understand what he is looking for, or should that remain unexplained at this point?
The question comes from an action on the page. It does not assume that he is frightened, being followed, or waiting for a bus. It separates what you need to communicate from what the excerpt has actually disclosed.
Your working note can now remain modest and reliable: Ada has begun closing the garage, Ben's voice interrupts that action, and his entrance follows. She responds to him as someone whose arrival matters. The reason he checks the road remains open.
That is enough to begin the next task. You have not diagnosed the screenplay, supplied a backstory, or improved the scene on the writer's behalf. You have read what is there closely enough that the pitch will not start by changing it.

Frequently asked questions
How should a reader approach a screenplay passage?
Separate where the scene happens, what happens within it, and what somebody says. Be able to retell a short passage without giving one person's action to another, making an unseen speaker visible, or adding a motive the page has not established.
What do INT., EXT., and NIGHT tell you in the bus garage example?
The first scene heading places us inside the bus garage at night; the later EXT. heading moves the presented scene outside. These headings identify inside or outside, the location, and the time of day. They do not say why Ben is late, and changing from INT. to EXT. does not establish a jump to another night when continued door opening and Ben's movement connect the portions.
What is the difference between O.S. and V.O. in the excerpt?
O.S. means off screen: Ben is speaking within the immediate scene but is not yet presented visibly. V.O., voice over, can instead mark narration or other speech heard over the images. Notation varies, so read an abbreviation with its surrounding action; in the example, Ada directs her answer toward the opening and the next section places Ben just outside, with no phone, recording, flashback, or older Ben narrating.
Why is “Ben switches off the radio... she slams the door” inaccurate?
It reassigns actions and invents details. Ada switches off the radio and starts lowering the door; Ben asks her to leave it; she stops rather than slams it. No demand to wait, no second entrance, and no established fury are written. A faithful reconstruction preserves who does what and the order in which the passage reveals it.
Does the passage tell us why Ben checks the empty road?
No. The excerpt does not disclose the reason; it remains open. A sharper author question is whether a pitch reader should understand what he is looking for or whether that should remain unexplained at this point. That question comes from an action on the page and does not assume he is frightened, being followed, or waiting for a bus.
