Brief a Film Trailer Without Retelling the Whole Plot
Brief a Film Trailer Without Retelling the Whole Plot
The brief arrives as an attachment: the full synopsis, a link to the film, and a line saying the trailer should give people "the whole movie, but in ninety seconds." That hands the editor a compression problem. You already did the compression. You wrote the synopsis, and it was never the interesting part.
A trailer is an invitation. An invitation has to be true about the thing it's inviting people to, and it has to leave something for the guest to show up for.
So the brief needs four things: a stated invitation, an inventory of material that can carry it, the limits on what may be shown, and a clear list of what the editor is free to decide. Anything else in the brief is either padding or a cut list in disguise.
Because the example below needs to stay fixed long enough to argue with, I've invented the film. Everything about Two Reels is stipulated for this article. No footage exists, no trailer was cut, and nobody watched anything.
Two Reels, 96 minutes. Nadia and Simon Aldridge have a weekend to reopen the Marigold, the 90-seat cinema their mother ran until four years ago, for one screening on Saturday at eight. Sixty-two people have said they'll come. The building is sold and the sale closes Monday morning. Nadia stayed in town and has spent four months cleaning. Simon didn't, and arrives Friday afternoon with a rented van and a borrowed mixer. In the booth there's a cardboard box in their mother's handwriting, and Nadia has asked him not to open it yet. On Saturday night he opens it, and inside is the sale agreement she signed eleven weeks ago. The cinema does not reopen. The last shot is the van idling outside on Sunday, engine running, nobody driving yet.
Whatever the trailer does, it has to be true about that film and not about a different one.
Name the invitation and the audience for this trailer
Two jobs get confused constantly, and they want opposite cuts. A sales piece — the thing that goes to a distributor, a festival programmer, a buyer — is addressed to someone assessing a project. That viewer wants to know what the film is, who it's for, what it resembles, what it cost to look at. A public trailer is addressed to someone deciding how to spend an evening. Same footage, different brief, and if you don't say which one you're commissioning, the editor will guess.
This article is about the public one. Even then, say who's in the room. For Two Reels, the trailer runs ahead of features in independent cinemas and on the distributor's own channels, in front of adults who have chosen to leave the house. That's a specific audience with a specific question: is this my kind of evening?
"Make it exciting" doesn't answer that question, because nobody can check it. A usable invitation is one somebody could disagree with. Two people who haven't spoken in four years have until eight o'clock to make a dead cinema work is arguable. An uplifting story about family is not a statement about anything.
For Two Reels, the invitation is roughly this: a warm, funny two-hander with a clock in it, in which two competent people who cannot talk to each other have to fix a building by eight. The film offers the pleasure of watching a physical problem get solved by people who are good at their jobs and bad at each other, and under that, the particular ache of a family that knows exactly how to work together. If a viewer remembers one line, it should be they have until eight.
The brief should also say what the invitation is not, because that's where trailers drift. The film is not a rescue story. Nobody saves the Marigold, and no cut of it should suggest a last-act reprieve. It's not a haunted-building story, and it isn't a mystery about what's in the box. Each of those is a promise the film declines to keep.
Choose truthful moments, not every major plot event
The instinct here is to list what happens, in order, starting with the setup. Trailers don't work by chronology; they work by function. Most usable material falls into four jobs: it establishes a situation, it shows a telling exchange between people, it leaves an action unresolved, or it moves the tone. An inventory sorts by those jobs. A synopsis sorts by time.
The second instinct is to include your favorite scenes. Your favorite scenes are usually the ones that pay off something the trailer hasn't set up, which is why they land in the film and die in a two-minute cut.
So the brief hands over an inventory with the context attached — what each moment actually is, and what it could carry. Context matters more than the shot, for reasons that get ugly later.
The marquee (Friday afternoon, before Simon arrives). Nadia on a ladder, spelling REOPENING SATURDAY 8 in plastic letters. The set is missing a U, so she improvises. Carries: the place, the task, a woman doing a job alone.
The van (Friday, four o'clock). Simon backs the rental van up to the stage door and very nearly takes out the marquee pole. Nadia watches from the doorway without moving. Carries: the arrival, the first laugh, the fact that these two don't move at the same speed.
The dead amp (Friday evening, booth). Simon flips the switch on the booth amplifier. Nothing. He flips it again. From the stairs, Nadia: "It ran in 1979." Carries: the obstacle in physical form, and one line of dialogue that says everything about their history.
The cable (Saturday morning). Gaffer tape down the aisle, a cable running from the projector to a borrowed mixer on the stage. One of Nadia's students walks on the tape and gets yelled at. Carries: the fix, its fragility, other people in the room.
The test tone (Friday night). Simon runs a tone through the empty house. It screeches, then settles. Nadia takes her hands off her ears and laughs. Carries: the first real laugh, and the size of the room when it's empty.
The door (Saturday morning). The basement door sticks in its frame and Nadia shoulders it open. Simon flinches at the bang, because he's coming up behind her with two reels of film and one of them slips an inch in his grip. Carries: comedy, and the contact-sport quality of their cooperation. Keep the flinch in a frame that shows what he's carrying.
The chairs (Saturday morning). Nadia's students unfold sixty-two chairs for sixty-two replies. Carries: warmth, and the fact that the stakes are other people.
The box (Friday night, booth). A cardboard box in their mother's handwriting. Nadia: "Not yet." Carries: a question. Nothing else.
The clock (Saturday, 7:52). The lobby clock, house lights at half, an empty auditorium with rows of folding chairs. Carries: the last beat of waiting.
The doors (Saturday, 8:00). Nadia turning the lock; a line of people on the pavement. Carries: the payoff image.
That's footage. Sound needs its own accounting, because a trailer's sound is where most of the accidental lies happen.
Available now: the film's production sound, the projector and room tone, the marquee letters ratcheting into the rail, the door bang, the tape peeling, and the score as delivered for reels one through four. Three usable lines sit in their own scenes: "It ran in 1979," "It's the same door it's always been," and "Not yet."
Not available yet: the end-title cue is still being mixed. Don't build your last eight seconds around it.
Not yours to assume: the record that plays in the lobby in reel one. It was licensed for the film. Whether that license reaches a trailer is a question for whoever holds the rights, and it's a slow question. Ask in week one or build without it.
Temporary by definition: any music you bring in that isn't the film's score. Label it in the cut so nobody downstream mistakes a temp bed for a decision.
Now two structures built from that one inventory. Neither is the answer.
Structure A — the collaboration (90 seconds). 0:00–0:08, the marquee, a letter drops. 0:08–0:16, the van nearly takes out the pole, cut to Nadia's face. 0:16–0:36, three problems in quick succession — the dead amp and Nadia's line from the stairs, the cable under tape in the aisle, sixty-two chairs opening row by row — dialogue overlapping. 0:36–0:50, the test tone, the screech, the laugh, held. 0:50–1:04, the door, with the reels in frame. 1:04–1:14, the box, "Not yet," no music. 1:14–1:24, 7:52 and the empty house. 1:24–1:30, the lock turning, the line outside, title.
Structure B — the countdown (90 seconds). 0:00–0:10, booth in half light, a hand on the switch, a click, nothing, room tone, no music. 0:10–0:24, hands only — wire, tape, meter lights — with the work itself as the rhythm. 0:24–0:38, first faces: the test tone screech and Nadia's laugh. This beat is not optional; without it the structure reads as a thriller. 0:38–0:54, fragments getting shorter — marquee letters, lobby clock, chair legs opening, tape, footsteps. 0:54–1:06, the box, "Not yet," silence, Simon's face. 1:06–1:20, 7:52, the empty house held long under one lamp. 1:20–1:30, the projector starts, title. Nothing about who's outside.
Both are honest, and they differ in a way worth arguing about. A tells you that people came. B keeps it open and gives up the crowd. A spends a small piece of the film's surprise in exchange for a stronger finish; B protects it and ends on a sound instead of a face. That's the editor's call, which is exactly why the brief should ask for two structures before blessing one.
Set disclosure limits that protect the film rather than obscure it
Name four things: the reversal, the ending, the resolution of the central relationship, and any object whose contents are the reversal.
In Two Reels, the reversal is that Nadia signed the sale eleven weeks ago. The ending is that the cinema closes anyway. The relationship resolves the way family arguments actually resolve — they're talking by Sunday, and he still drives home. The object is the box, and the box contains the papers.
The reasoning matters more than the list. The film's middle works because the audience spends it not knowing, and their discomfort is the engine. A trailer that shows the signed agreement gives an audience a hundred minutes of waiting for a scene they've already watched. The line "You could have told me," from the fight in reel five, does the same thing in five words. Leave it out.
The opposite failure is worth naming too, because it's more common and harder to see. A trailer that withholds the situation — ninety seconds of booth shadows and a banging door, no names, no eight o'clock, no reason — isn't protecting anything. It's just meaningless. Withholding how it turns out is craft. Withholding what's happening is a shrug.
Here's where the inventory earns its keep. Take the same real footage and cut this:
0:00–0:05 Black. A low synth drone.
0:05–0:12 A hand on a door handle. The door bangs open, loud, with a stinger on the impact.
0:12–0:20 Simon's face, alarmed, held too long — cropped above the reels in his arms.
0:20–0:28 "Not yet," moved here from the box scene in the booth, laid over a dark doorway.
0:28–0:36 The empty auditorium, held under the drone.
0:36–0:45 Title.
Read the three cuts side by side. The invitation offered is a suspense film about a locked room and a secret somebody won't explain. The disclosure is nothing at all — a lying trailer is not automatically a spoiling one, and people often confuse the two. The false implication is concrete: danger to a person, a hostile secret, a genre.
Every shot in it is real. Nothing has been fabricated or taken from a different production. The lie lives in the crop, the order, the drone, and one line of dialogue moved from one scene to another. That's why a brief can't fix this with a list of forbidden shots. It has to name the implication the cut can't carry.
The cost isn't abstract. You recruit two rooms wrong. People who wanted a warm two-hander never come, and the ones who do come expecting dread spend the whole film waiting for something that never arrives — and they tell their friends the trailer lied.
Define editorial freedom and the facts that are not creative variables
Say plainly what belongs to the editor: order, rhythm, where the title lands, whether the crowd appears at all, whether the score is used, how much dialogue survives, whether the whole thing leans comic or leans countdown. Then say what doesn't belong to them.
Credits come from the production's approved block. The title treatment comes from the artwork that exists. In this case no release date is set, so a date card is either left out or clearly marked provisional. No rating has been assigned, so there's no rating card yet. Music is a rights question with an actual owner and an actual timeline, and it isn't a creative variable the brief can wave through.
Runtime and delivery specs come from whoever commissioned the trailer, not from a rule about how trailers work. Here the distributor asked for 90 seconds maximum and asked for both a widescreen master and a vertical crop. If a different platform asks for 30 seconds, that's a different brief, and the invitation above may not survive the cut.
One more thing belongs in this section: reordering across days is normal and usually fine. Structure A puts the door — Saturday morning — before the box, which happens Friday night, and nobody is misled, because the trailer never claims a sequence of events. What matters isn't whether the order is chronological. It's what the new order says. The door with the reels in frame says these two are a mess together. The door cropped and scored says something is in this house. Same footage, opposite claims.
Review the trailer against the invitation you actually briefed
Three questions, asked in this order.
Does the cut give one legible reason to watch? Not five. One a viewer could repeat on the way home.
Does it keep the disclosures you named? Watch it once knowing the ending, and check whether the box has become an answer.
Does it promise something the film can meet? A viewer who sees the film should feel the trailer was honest, not just memorable. The door version would probably test as the most gripping of the three, and that is precisely the argument for writing the limits down before anyone falls in love with it.
If the review finds a false implication, the fix is almost always to restore a shot's context or use a different shot. A disclaimer card at the end patches nothing.
And check your own instructions before you endorse a structure. If the editor brings you two, read the one you like least before deciding. Trailers get killed by first impressions in both directions.
Here is the brief that comes out the other end. The open list is the job. Everything above it is the shape the job has to fit.
Trailer brief: Two Reels, 90-second public trailer.
The invitation. Two people who haven't spoken in four years have until eight o'clock on Saturday to make a dead cinema work. Warm, funny, one location, a clock running the whole time. If a viewer remembers one line, it should be they have until eight.
Who's watching. Adults at independent cinemas ahead of features, plus the distributor's channels. People deciding what kind of evening this is, not assessing a project. If this were a sales piece, the brief would say so, and it would ask for different things.
Available material. The ten moments above, with their contexts attached. Reorder them, combine them, drop half. Don't use a moment without the thing that makes it true — the reels in Simon's arms, the students standing on the tape, the empty house at 7:52 rather than the empty house on Sunday morning.
Not available yet. The end-title cue, still being mixed. The lobby record, whose license may not reach a trailer. Anything you bring in with a temp bed is temp; mark it as temp in the cut.
Keep out. The signed agreement. The fight in reel five. The interior of the box. The line "You could have told me." Treat the box as a question, not an answer.
Don't imply. Danger to a person. Dread. A haunted building. The door is a door. Any cut that needs an audience to fear for somebody's safety is selling a film that doesn't exist.
Fixed. Title treatment and the credit block come from the production's approved artwork, as written. No release date is set, so no date card unless it's marked provisional. No rating has been assigned, so no rating card.
Specs. 90 seconds maximum. Widescreen master plus a vertical crop. From the distributor's request, not from a rule.
Open. Order. Rhythm. Where the title lands. Whether the crowd appears at all. Whether the score is used at all. Whether it's cut as a comedy or as a countdown. Bring me two structures before you commit to one — and tell me what each one is giving up.
Frequently asked questions
What four elements should a trailer brief contain?
A stated invitation, an inventory of material that can carry it, the limits on what may be shown, and a clear list of what the editor is free to decide. Anything else in the brief is either padding or a cut list in disguise.
How does a public trailer brief differ from a sales piece?
A sales piece is addressed to a distributor, festival programmer, or buyer assessing a project. That viewer wants to know what the film is, who it is for, what it resembles, and what it cost to look at. A public trailer is addressed to someone deciding how to spend an evening. Same footage, different brief, so say which one you are commissioning.
What kinds of moments belong in a trailer inventory, and how are they sorted?
Useful material can establish a situation, show a telling exchange between people, leave an action unresolved, or move the tone. An inventory sorts by those jobs; a synopsis sorts by time. Favorite scenes often pay off something the trailer has not set up, so the brief should attach context to each moment rather than just list shots.
Which disclosures should be kept out, and why?
Name the reversal, the ending, the resolution of the central relationship, and any object whose contents are the reversal. In the invented film, that means keeping out the signed agreement, the fight in reel five, the interior of the box, and the line You could have told me. The film's middle works because the audience spends it not knowing, and showing the answer creates waiting for a scene already watched.
What is a false implication, and how can it happen with real footage?
A cut can imply danger, dread, a haunted building, or a genre without fabricating shots. In the invented suspense-style cut, the lie lives in the crop, the order, the drone, and one line of dialogue moved from the box scene to a dark doorway. The fix is usually to restore a shot's context or use a different shot; a disclaimer card at the end patches nothing.
