Log Line

A log line is the most concise way to sell a story—one, maximum two sentences that distill the emotional core and tension of a film. It's not the synopsis, not the treatment, not even the first page of the exposé. It's the hook. You rarely need it on set, but in development, it's indispensable: it forces you to know what it's really about.

The structure is always brutally simple: protagonist + their central conflict + what's at stake. An example from practice—not from any film, but from pitch situations that actually worked: "A CIA agent must rescue his own son from the hands of terrorists before he becomes a tool against the US." Or even tighter: "A physical therapist discovers her deceased husband was involved in the murders she is currently investigating." No names, no subplot details—just the axis around which everything revolves.

Many filmmakers underestimate the log line or dismiss it as a marketing artifact. Wrong. It's an internal navigation tool. If you notice during editing that a scene isn't maintaining tension, look back at your log line—does the scene still fit this core promise? Often, this helps you recognize that your second-act slump is self-inflicted, not inevitable. You'll be surprised how often a good log line makes your editing decisions easier later on.

The log line differs from the pitch—the pitch tells the story actively, with energy, with voices. The log line is written, precise, emotionless in form, but emotional in substance. It's also not the teaser you'll write later for social media. It's for yourself and your team: a promise the film must fulfill. If your log line sounds boring, your screenplay idea is usually not ripe enough yet. That's bitter, but it saves you months of work.

Write your log line before you start the first draft. Tell it to your producers, your cinematographer, your production designer. Everyone on the project should have it in mind—it's the common anchor when the debates begin.
