How to Write a Film Logline—Not a Tagline
How to Write a Film Logline—Not a Tagline
A film logline tells a prospective collaborator what the story puts into motion. A tagline can leave that information out and still do its job. The difference becomes easier to see when both describe the same film.
Here is a constructed example, The Last Screening:
Tagline: One last night. Everything left unsaid.
Logline: When the screening file fails on a cinema’s final night, its projectionist must seek a print from the former collaborator whose work she claimed as her own.
The tagline suggests an ending, unfinished business and perhaps regret. It does not tell us whose unfinished business, what brings it to the surface, or what anyone has to do. The logline supplies those things. A practical failure forces a person to ask for help from someone she has wronged.
Neither piece of copy needs to perform the other’s job. The trouble starts when a pitch offers the tagline where the recipient needs the story.
Screen Australia’s Story Documents—Drama makes this distinction between promotional phrasing and a logline carrying substantive story information. Its examples also allow for different kinds of dramatic pressure, including emotional and ensemble stories.[^1] That is useful craft guidance, not a rule that every US recipient wants the same sentence or length.
Find the situation before you write the sentence
For this exercise, the fictional story is fixed. Lena is preparing a cinema’s final screening. The digital copy fails, and no replacement digital copy can arrive in time. Noor, her former collaborator, has a screenable print. Years earlier, Lena took sole public credit for their shared restoration work. The closing-night program repeats that claim. Noor refuses to supply the print for an evening that erases them again.
Those facts give us something to compress. Without them, we might spend an hour improving “a moving story about reconciliation” without making the film any more intelligible.
Begin with plain notes rather than a polished sentence. Identify who the film follows, what changes their situation, what they now pursue or resist, and what makes that pursuit difficult. Then ask which relationship or circumstance makes the pressure particular to this film.
For The Last Screening, the notes are simple: a projectionist; a failed screening copy; an attempt to obtain a replacement; the only available print held by the person whose contribution she erased. The final night matters because postponing the event is not an equivalent solution. The credit dispute matters because this is not merely a search for another copy.
These are questions to ask of your story, not slots you must fill with invented answers. A screenplay may follow a group. Its pressure may come from conflicting responsibilities rather than an enemy. A character may struggle to refuse something rather than acquire it. Name the actual movement instead of giving the film a more conventional one for the sake of a neat sentence.
The notes should also distinguish what the character wants from what you think the film means. Lena wants the advertised screening to happen. You might read the story as being about authorship, accountability or the limits of an apology. Those readings become useful because the situation gives them something to act through. Substituting the theme for the situation removes that mechanism.
A premise is a start, not necessarily a logline
Consider this introduction:
A projectionist prepares a beloved cinema’s final screening.
It establishes a person, a place and an occasion. It might be an accurate premise statement. But it gives the recipient little basis for distinguishing a night of reminiscence from a technical comedy, an ensemble farewell or a confrontation between former collaborators.
Now add the failed copy:
On a cinema’s final night, a projectionist searches for a replacement screening copy.
The sentence has movement. It still leaves out the difficulty that makes this particular search worth following. Add the person holding the print and the reason asking them is difficult, and the story’s shape changes. Lena cannot solve the problem by being more efficient at her job. The practical obstacle brings her past conduct into the room.
That is the useful distinction to look for in your own draft. A premise says what situation exists. A logline usually needs enough of the pressure within that situation for this reader to understand what the film will follow. It does not need to account for every turn that follows.
A stranger’s ability to repeat your theme is therefore a weak check. “It’s about forgiveness” could describe many films. “She needs help from the collaborator she publicly erased” tells you that the central relation has survived the compression.
Keep the detail that changes the conflict
It is tempting to treat every word as equally expendable. They are not.
Compare an overloaded version:
Lena, a meticulous projectionist who has spent years at a much-loved local cinema, prepares its final program, but when the scheduled digital copy fails, she must contact Noor, an estranged former restoration collaborator whose contribution she once omitted from the public account of their work, to borrow the only available print.
Most of that is intelligible. It asks the reader to hold a long introduction before reaching the problem, then a long relationship history before reaching the request. The sentence contains useful information in an order that makes it expensive to follow.
Now strip it too far:
A projectionist must overcome her past to save a screening.
This is shorter, but “her past” conceals the obstacle. The phrase could mean guilt, a technical mistake, an addiction, a former employer or a secret identity. The reader has to supply the story we removed.
The better edit cuts around the conflict. “Projectionist” makes Lena’s responsibility clear. “Final night” establishes why this screening cannot simply happen another week. “Former collaborator” explains the relationship. “Whose work she claimed as her own” explains the damage. Her name is not necessary in this sentence; the credit dispute is.
One practical revision method is to remove a detail and describe what changed. Without “meticulous,” we lose a proposed character quality, but still understand the situation. Without the credit dispute, we lose the reason the request is hard. Without the final night, we weaken the time pressure. Make cuts according to those losses, not according to a ban on adjectives or names.
Some details can do more than one job. “Former collaborator” suggests a shared history and a broken working relationship without requiring a biography. But compressed language still needs to be exact. “Rival” would be shorter and more dramatic; it would also change the relationship. “Betrayed” might be accurate, but tells us less than the actual action.
Let the syntax carry the right person
Our first working version could read:
When a cinema’s final screening copy fails, its projectionist must persuade the estranged collaborator she denied credit to lend the surviving print.
The information is present. The sequence “denied credit to lend” makes the reader pause to untangle what belongs to whom. This is a sentence problem, not a story problem.
Revising it gives us:
When the screening file fails on a cinema’s final night, its projectionist must seek a print from the former collaborator whose work she claimed as her own.
The opening names the disruption. The main clause belongs to the projectionist. The final clause explains why seeking the print is difficult. We have not added an event or improved Lena’s behavior. We have made the existing relation easier to follow.
Watch for grammatical accidents that change agency. “A disgraced projectionist is offered one last chance” makes somebody else appear to create Lena’s opportunity. “A collaborator withholds a print” makes Noor’s refusal the initiating problem and conceals Lena’s conduct. Either could suit another story. Neither is a neutral shortening of this one.
Read the sentence aloud for the connections, not as a performance. Notice where you have to restart, clarify a pronoun or mentally insert missing context. A logline can be a long sentence without being a tangled one. Two clear sentences may be preferable when the recipient permits them.
State the stakes without inventing a bigger film
The screening matters because it is the cinema’s last night and Lena’s final opportunity to conduct that farewell honestly. The situation does not need a threat of death, financial ruin or public scandal to become dramatic.
It also does not need this version:
A projectionist must reconcile with her former collaborator to save their cinema from closure.
That is a different film. In the constructed source, the cinema closes as planned. Lena corrects the public credit; Noor agrees to share the screening. Cooperation for one evening does not establish a fully repaired friendship.
The false version is attractive because it wraps the story in a familiar rescue objective. It would also create the wrong expectation for every later page of the pitch. Sharpening stakes means naming what the story puts at risk, not increasing the scale until the sentence sounds more saleable.
You need not disclose the final correction in the logline to establish the conflict. “Whose work she claimed as her own” tells the recipient why the request matters without telling them precisely how Lena responds. The eventual assessment synopsis can explain that response and its limits.
Adapt the length, not the facts
A recipient’s instructions govern the version you submit. For example, Sundance Institute’s published 2027 Development Track application specifies a logline of up to 75 words in one or two sentences.[^2] That is one program’s requirement, not a recommended length for every deck or every filmmaker. It is a ceiling, not a target to fill.
First keep a clear base version. Then make a separate version for an actual limit rather than repeatedly overwriting the only copy you understand.
Suppose a hypothetical form gives this fictional project 30 words. Here is a shorter alternative:
On a cinema’s final night, a projectionist needs a replacement print from the former collaborator whose restoration work she claimed as her own.
It keeps the relationship and the pursuit but drops the explicit digital-copy failure. Whether that is the right trade depends on what the recipient needs and what else accompanies the sentence. The limit alone cannot make that editorial choice for you.
Do not solve the constraint by turning the prose into shorthand. Unexplained initials, compressed punctuation and a row of genre labels may save visible space while increasing the work of understanding. Remove a less necessary fact before damaging the sentence’s connections.
For an ensemble, make the same decision at the appropriate scale. Name the group and its shared predicament when that is how the story is organized. Do not promote one character to protagonist merely because a template expects a single person. Similarly, a film built around observation or a formal pattern needs a truthful account of that experience, not goals manufactured for the pitch.
Check what the sentence actually communicated
Give the base logline to someone who has not heard the whole story. Ask them to describe the situation, who needs what, and what makes it difficult. Do not explain the missing pieces before they answer.
Treat their response as information about this sentence and this reading, not proof of what all producers will think. A confused answer may expose a pronoun problem. It may reveal an omission. It may also come from an assumption the reader brought with them. Go back to the wording and locate the difference before revising.
Keep the full source notes beside you during that revision. For The Last Screening, the essential check is whether the reader recognizes a practical request complicated by Lena’s denial of someone else’s work. They need not predict her correction, Noor’s response or the final image of the cinema closing.
Save the usable base version and any recipient-specific variant with their purpose identified. Keep the discarded backstory in the synopsis notes, where it may still matter. The tagline can stay too. It has a different space to occupy. On the story-introduction page, give the reader the situation they came to understand.

Frequently asked questions
What is the practical difference between a logline and a tagline?
A tagline can suggest mood or unfinished business without saying whose story it is or what happens. A logline tells a prospective collaborator what the story puts into motion. In the constructed example, the tagline says One last night. Everything left unsaid, while the logline says the screening file fails on a cinema's final night and the projectionist must seek a print from the former collaborator whose work she claimed as her own.
How should I begin if I only have a vague sense of the film?
Begin with plain notes rather than a polished sentence. Identify who the film follows, what changes their situation, what they now pursue or resist, and what makes that pursuit difficult. Then ask which relationship or circumstance makes the pressure particular to this film. These questions are not slots to fill with invented answers; name the actual movement of your story.
Why can a premise statement fail as a logline?
A premise can establish a person, place and occasion without giving the recipient enough to distinguish one kind of film from another. A projectionist prepares a beloved cinema's final screening could describe reminiscence, technical comedy, ensemble farewell or confrontation. Adding the failed copy creates movement, but the story's shape changes further when the only print is held by the person whose contribution was erased.
Which details should I cut or keep when tightening a logline?
Remove a detail and describe what changed. Without meticulous, you lose a proposed character quality but still understand the situation; without the credit dispute, you lose the reason the request is hard; without the final night, you weaken the time pressure. Cut according to those losses, not according to a ban on adjectives or names. Keep details that change the conflict, such as former collaborator or whose work she claimed as her own.
How should I handle a recipient's word limit?
A recipient's instructions govern the version you submit. The body gives Sundance Institute's published 2027 Development Track as an example specifying a logline of up to 75 words in one or two sentences, but that is one program's requirement, not a universal recommendation. Keep a clear base version, then make a separate version for an actual limit. Do not solve the constraint by turning the prose into shorthand that removes necessary connections.
