How the most compressed form in screenwriting reveals everything about what your script is and is not

One Sentence

LOS ANGELES — The logline — a single sentence of 25-50 words that captures the core concept, protagonist, and conflict of a screenplay — is simultaneously the most undervalued and most important piece of writing a screenwriter produces. It is undervalued because it is short and because writers who have spent months on a script resist reducing it to a sentence. It is important because it is what development executives, agents, managers, and producers read first, and in most cases read instead of the script.

A logline that works does three things simultaneously: it communicates what is distinctive about the concept, it implies the protagonist’s specific problem and what they stand to lose, and it creates sufficient curiosity about the outcome that the reader wants to read the script. A logline that fails does one or two of these things while neglecting the third, usually by summarising rather than enticing — telling the reader what happens rather than making them want to find out.

The Elements and Their Function

The conventional logline structure includes: a protagonist with a specific quality that is relevant to the story (not just “a detective” but “a detective with severe OCD”), a situation or world that establishes stakes (not just “in New York” but “in a city where memory can be stolen”), and a core conflict or question that the story will resolve (not “must solve a crime” but “must solve a crime using the only ability he has tried to destroy”).

The specificity is not decorative. Generic elements — “a young woman,” “a dangerous world,” “a fight for survival” — appear in thousands of loglines and communicate nothing about why this script is different from every script that fits the same description. Specific, concrete, unexpected details — the OCD detective, the stolen memory, the ability he has tried to destroy — are memorable, communicable, and suggest a writer with a specific vision rather than a writer who has assembled genre conventions.

Testing Your Logline

The standard test of a logline is whether a stranger understands what the film is about from the sentence alone, without clarification. The secondary test is whether the stranger, understanding what the film is about, wants to see it. Most first-draft loglines pass the first test and fail the second. The revision work on a logline is conceptual as much as editorial: if the logline is dull, the concept may need rethinking, not just the sentence. The Script Magazine logline resources include examples and exercises. The sentence is thirty words. The work behind it is everything.
