50+ screenwriting terms explained by a working screenwriter — with real screenplay examples, common mistakes, and cross-references. Not a dictionary. A field guide.
An act break is the moment at the end of an act in a television script (or between acts in a feature) where tension peaks and a question is left unresolved, compelling the audience to continue watching. In television, act breaks originally corresponded to commercial breaks and are the structural hinges of episodic storytelling.
Action lines (also called scene description or narrative) are the non-dialogue portions of a screenplay that describe what the audience sees and hears on screen. They sit between scene headings and dialogue blocks, written in present tense, and convey physical action, setting details, and character introductions.
An ad-lib (or ad lib) is an instruction in a screenplay indicating that characters should improvise dialogue, typically background conversation, reactions, or atmospheric chatter. Written as "(ad-lib)" in a parenthetical or described in an action line, it signals that the specific words do not matter — the energy and context do.
The antagonist is the force that opposes the protagonist's goal, creating the central conflict of the screenplay. An antagonist can be a person, an institution, nature, or the protagonist's own psychology. The antagonist does not need to be evil — they need to be an effective obstacle to what the protagonist wants.
The B-story is the secondary plotline that runs alongside the main story (A-story) in a screenplay. It often involves a relationship, a thematic counterpoint, or a subplot that mirrors or contrasts with the protagonist's central journey. The B-story typically intersects with the A-story at key structural points.
In screenplay dialogue, a "beat" is a pause — a moment of silence where a character absorbs, decides, or reacts before speaking or acting. Written as "A beat." or simply "Beat." in the action lines between dialogue blocks, it controls pacing and creates space for the audience to feel the weight of a moment.
A character arc is the internal transformation a character undergoes over the course of a screenplay. The protagonist typically starts with a flaw or false belief, faces experiences that challenge it, and either changes (positive arc), fails to change (negative arc), or remains steadfast while changing the world around them (flat arc).
The character name (or character cue) is the capitalized name that appears above a block of dialogue, identifying who is speaking. It sits roughly 3.7 inches from the left margin in standard screenplay format and is always in ALL CAPS. The first time a character appears in an action line, their name is also capitalized.
The climax is the highest point of tension in a screenplay — the scene or sequence where the central conflict reaches its ultimate confrontation and the protagonist either succeeds or fails. It typically occurs in the final fifteen pages and is the moment the entire story has been building toward.
A cold open is a scene or sequence that plays before the title card or main credits, designed to hook the audience immediately. Common in television (especially procedurals and dramedies), cold opens drop the viewer into action, mystery, or an arresting image before the story formally begins.
Coverage is a written evaluation of a screenplay prepared by a reader for a production company, agency, or studio. It includes a logline, synopsis, comments on craft elements (structure, character, dialogue, concept), and a recommendation: PASS, CONSIDER, or RECOMMEND. Coverage is the gate most scripts must pass through.
The denouement is the final section of a screenplay that follows the climax, showing the new equilibrium after the central conflict resolves. It ties up remaining story threads, demonstrates how the protagonist has changed, and gives the audience an emotional landing. It should be brief — typically one to five pages.
Dialogue is the spoken words of a character in a screenplay. It appears indented beneath the character name, roughly 2.5 inches from the left margin, and runs no wider than about 3.5 inches. Dialogue is what characters say out loud — distinct from action lines, parentheticals, and voice-over narration.
Dramatic irony is a storytelling device where the audience knows something that one or more characters do not. This gap between audience knowledge and character knowledge creates tension, suspense, dread, or dark comedy depending on how it is deployed. It is one of the most powerful tools in a screenwriter's arsenal.
An ensemble is a group of characters who share roughly equal narrative weight, without a single clear protagonist dominating the story. Ensemble screenplays distribute screen time, arcs, and dramatic focus across multiple characters whose stories interweave and often converge at the climax.
Exposition is the delivery of background information the audience needs to understand the story — character histories, world rules, plot context, and relationships. It is essential for orienting the viewer but dangerous when delivered clumsily, which is why screenwriters call heavy-handed exposition "expository dialogue" as a pejorative.
In medias res (Latin: "in the middle of things") is a narrative technique where the story begins in the middle of the action rather than at the chronological beginning. The audience is dropped into an event already in progress and given context later through flashbacks, dialogue, or gradual revelation.
The inciting incident is the event that disrupts the protagonist's status quo and sets the central story in motion. It is the moment the movie actually begins — before it, we have setup; after it, we have a story with stakes. In most features, it lands between pages 10 and 15.
An intercut is a formatting device that allows a screenwriter to cut freely between two or more locations within the same scene, typically during a phone call or parallel action. Once INTERCUT is established, you write dialogue and action for both locations without repeating scene headings.
The midpoint is a major story event occurring roughly halfway through the screenplay (around page 55 in a 110-page script) that raises stakes, shifts the protagonist's approach, or reframes the central conflict. It divides Act II into two distinct halves and prevents the narrative from sagging.
A monologue is an extended speech by a single character, typically running half a page or more, delivered without significant interruption. In screenwriting, monologues are high-risk, high-reward — when they work, they are the scenes audiences remember. When they do not, they stop the movie cold.
A montage is a sequence of brief scenes or images, usually without dialogue, that compresses time or shows parallel actions. In screenplay format, montages are introduced with a heading like MONTAGE or SERIES OF SHOTS, followed by lettered or dashed items describing each shot. They end with END MONTAGE or a new scene heading.
Off-screen (abbreviated O.S. or O.C. for off-camera) indicates that a character is speaking from within the scene but is not visible on screen at that moment. The character is physically present in the same location and time — they are just outside the camera's frame, behind a door, in another room, or otherwise out of view.
An option is a contractual agreement where a producer or company pays a screenwriter a fee for the exclusive right to purchase the screenplay within a set period, typically 12 to 18 months. The option fee is usually a fraction of the full purchase price. If the option expires without the project moving forward, all rights revert to the writer.
A page-one rewrite is a comprehensive overhaul of a screenplay that rethinks the story from scratch — new structure, possibly new characters, potentially a different take on the same premise. Despite the name, it does not mean literally starting from a blank page, but it signals that the existing draft's problems are foundational, not cosmetic.
A parenthetical is a brief direction placed in parentheses between the character name and their dialogue. It indicates how a line should be delivered or who the character is speaking to. Parentheticals sit on their own line, indented slightly more than dialogue, and should be used sparingly.
A pitch is an oral or written presentation of a screenplay idea to producers, executives, or representatives with the goal of selling the concept or getting hired to write it. Pitches range from a 30-second elevator pitch (logline + hook) to a 20-minute room pitch (full story with performance) and are a core survival skill for working screenwriters.
Plant and payoff (also called setup and payoff or Chekhov's gun) is the technique of introducing a seemingly minor detail early in the script that becomes significant later. The plant establishes the element. The payoff activates it. Done well, the audience feels the satisfaction of a story that was planned, not improvised.
A polish is a light revision pass on a screenplay that refines dialogue, tightens action lines, fixes inconsistencies, and improves pacing without altering the story's structure, characters, or plot. It is the final sandpaper, not a rebuild — the screenwriting equivalent of editing for clarity and rhythm.
The protagonist is the central character whose journey drives the screenplay. They are not necessarily the hero or the most moral character — they are the character whose choices determine the plot, whose internal transformation (or refusal to transform) carries the theme, and whose perspective anchors the audience's experience.
A scene heading (also called a slug line) is the bold, capitalized line that opens every new scene in a screenplay. It tells the reader three things: whether the scene is interior or exterior (INT. or EXT.), the location, and the time of day. Every scene change requires a new scene heading.
A set piece is an elaborate, self-contained sequence built around a specific location, challenge, or spectacle that showcases the film's highest production value. Set pieces are the memorable tentpole moments audiences talk about after leaving the theater — the sequences that trailers are cut from.
A shooting script is the final, production-ready version of a screenplay that includes scene numbers, revision colors, and technical details needed by the production team. It is the version that gets distributed to department heads, broken down by the AD, and used on set every day of the shoot.
Show, don't tell is the foundational screenwriting principle that visual storytelling should convey information through action, behavior, and imagery rather than through dialogue or narration explaining it. A character slamming a door shows anger more powerfully than a character saying "I'm angry." The screen is a visual medium — let it be visual.
A slug line is any capitalized, standalone line that provides location or technical orientation. While often used interchangeably with "scene heading," slug lines also include secondary slugs (also called mini-slugs) — shorter headings within a scene that redirect attention to a new area without triggering a full scene change.
A spec sale is the purchase of a completed spec script by a production company or studio. It is the lottery ticket of screenwriting — a writer finishes a script on their own time, puts it on the market, and a buyer acquires it outright or against a production bonus. Spec sales range from low five figures to seven figures depending on the project.
A spec script (short for speculative screenplay) is a script written on speculation — without a development deal, commission, or guarantee of sale. It is the calling card of the screenwriting industry. Most produced feature films and many TV episodes began as spec scripts written by writers hoping to sell or use them as samples.
Subtext is the meaning beneath the surface of dialogue — what characters actually communicate without saying it directly. When a character says "I'm fine" but means "I'm falling apart," the gap between word and meaning is subtext. It is the most important skill in writing dialogue and the hardest to master.
Superimpose (often abbreviated SUPER:) is a formatting instruction to overlay text on the screen image. It is used for location titles, time stamps, date cards, and any on-screen text the audience reads. In screenplay format, SUPER: appears in the action line, followed by the text to be displayed in quotes.
A supporting character is any character who serves the story without being the protagonist or primary antagonist. Supporting characters provide exposition, reflect the protagonist's arc, add texture to the world, create subplots, and often deliver the story's thematic argument through their own smaller arcs.
A table read (or read-through) is a group reading of a screenplay where actors sit around a table and perform the script aloud, usually for the first time. Writers, directors, and producers listen to identify problems with pacing, dialogue, character voice, and story logic that are invisible on the page.
A teaser is the opening segment of a television episode, typically one to five pages, that precedes the first act and title sequence. Functionally similar to a cold open, the teaser establishes the episode's central problem, reintroduces the world for returning viewers, and hooks the audience into staying through the commercial break.
Three-act structure is the foundational narrative framework dividing a screenplay into setup (Act I), confrontation (Act II), and resolution (Act III). In a standard 110-page feature, Act I runs roughly 25-30 pages, Act II is 50-60 pages, and Act III is 20-30 pages. It is the skeleton that most produced films follow, whether consciously or not.
A transition is a screenplay instruction indicating how one scene moves to the next. Common transitions include CUT TO:, SMASH CUT TO:, DISSOLVE TO:, and FADE OUT. They appear flush right or at the right margin in standard formatting. In modern screenwriting, transitions are used rarely — the assumption is that every scene change is a cut.
A treatment is a prose document, typically 5 to 25 pages, that tells the story of a screenplay in present-tense narrative form without dialogue or formatting. It covers all major plot points, character arcs, and structural turns, giving producers and executives a complete picture of the film before a script is written or commissioned.
Voice-over is dialogue spoken by a character who is not physically present in the scene, typically narrating or commenting on the action. In screenplay format, it is indicated by (V.O.) after the character name. Voice-over comes from outside the scene's time and space — the narrator is speaking from elsewhere.
Voice-over narration is a sustained use of voice-over (V.O.) as a storytelling device throughout a screenplay, where a character narrates events, provides commentary, or offers perspective that layers on top of the visual story. It differs from incidental V.O. (a character reading a letter) by being a structural choice that shapes the entire film's tone.
