Common Logline Mistakes
Most loglines fail in the same handful of ways. The good news: once you can name the traps, you can spot them in your own logline in seconds — and fix them just as fast.
I've read thousands of loglines, and the failures are remarkably consistent. They don't fail in a thousand creative ways — they fail in about eight predictable ones. That's actually great news, because it means you can run your logline against a checklist and catch the problems yourself before anyone else does. Here are the traps, and the fix for each.
The eight most common mistakes
"A man goes on a journey of self-discovery." No specific goal, no conflict, no movie. Fix: add a concrete external goal and a clear obstacle — something we can see happening.
Three subplots, five characters, and a run-on sentence nobody can follow. Fix: strip it to the single spine — one protagonist, one goal, one central conflict.
"When Dave meets Karen, they must help Mr. Fisk…" — we don't know who these people are. Fix: replace names with identities: "a burned-out paramedic," "a ruthless landlord."
We know what the hero wants but not what happens if they fail — so we don't care. Fix: spell out the cost of failure, or the ticking clock, right in the sentence.
Things happen to the hero, but they never chase anything. Fix: give them an active goal — a verb they're driving, not just a situation they're enduring.
Everything's technically present, but it's flat — nothing makes it this movie. Fix: find the built-in contradiction or fresh angle and put it front and center.
"…and finally defeats the villain and saves the town." Now there's no question left to pull us in. Fix: pose the question; don't answer it. End on the tension, not the resolution.
Sixty words, three clauses, and the reader's lost by the end. Fix: cut to one sentence, 25–40 words. If you can't say it in a breath, it isn't done.
The self-edit pass
When you finish a logline, run it against this quick gauntlet: Can I picture the protagonist? Is there a clear, active goal? Are the stakes obvious? Is there a hook or irony? Did I avoid names and plot spoilers? Can I say it in one breath? If any answer is "no," you've found your fix. Then do the ultimate test — say it out loud to someone and watch their face. A logline that works produces a spark; a logline that fails produces a polite "…okay." Trust the face, not your own attachment to the words.
Producers and readers have seen these same mistakes ten thousand times, which is why a clean logline stands out so sharply — it signals a writer who knows the craft. A vague or bloated logline does the opposite: it tells a busy executive, before they've read a page, that the script probably has the same problems. Fixing your logline isn't just about the sentence; it's about the first impression that decides whether your script gets read at all.
That completes the logline foundations — you can now define it, build it, recognize what works, and dodge what doesn't. But a logline is only the front door. In Module 2 we walk through it and build the full pitch, starting with how to expand that one sentence into a pitch that sells.
