There’s a lot of mystery surrounding log lines. What are they? Do screenwriters really need them? Is there any correlation between log lines and actual logs in the forest?

When prodded, Google coughed up these top two definitions:

1)A log line or logline is a brief summary of a television program or film, often providing both a synopsis of the program’s plot, and an emotional ‘hook’ to stimulate interest.” – Wikipedia

Okay. So according to Wikipedia, the log line for “The Bourne Identity” would look like the summary provided on Net Flix…

“Wounded to the brink of death and suffering from amnesia, Jason Bourne is rescued at sea by a fisherman. With nothing to go on but a Swiss bank account number, he starts to reconstruct his life, but finds that many people he encounters want him dead. Bourne realizes, though, that he has the combat and mental skills of a world-class spy, but who does he work for?”

2) “A log line is a one sentence summary of your script.” – Scriptologist

In accordance with this definition, something like this might make more sense: “A man with a damaged memory struggles to uncover his identity while fighting off an army of trained assassins, ultimately learning that he too was one of these assassins, and escaping to an island with a pretty girl.”

A little clunky. Not much of a “hook to stimulate interest” there either.

At Script Quack Script Analysis, our definition of log lines bridges the gap between the two excerpted above. We like to think of the log line as a one sentence description of your story, outlining the key elements of hero, antagonist, conflict and irony.

Our ideas about log lines were largely sculpted by Blake Snyder’s interpretation in “Save the Cat.” Snyder’s book focuses on crafting commercially viable screenplays. As such, he also suggests that your log line indicate audience and cost.

But still, knowing all that doesn’t shine a very bright light on the process of crafting a good log line. It’s often an arduous, painstaking task, where the patient screenwriter must turn a pile of words over and over again, until they somehow resemble a smooth, seamless movie idea.

And that’s why log lines are so essential. They force you to sculpt, trim and prune your idea into one that’s worth outlining, writing and re-writing a million times.

Sometimes attempting to form a log line will teach you that your idea just doesn’t work. But when you’ve got a good idea, your log line will be the first nugget of gold that will guide you throughout the entire process.
So without further delay, let’s mold a messy, nebulous idea into a strong log line that indicates hero, antagonist, conflict, irony, audience and cost. We’ll continue to use “The Bourne Identity” for this exercise.

In the beginning, all you’ll really have is the bones of your idea, or story. The first step is to write all that down, as succinctly as you can. It’ll be very loose, and much too long at first, but don’t worry about that for now.

For Bourne, maybe you’d write something like the Netflix blurb, something like this:

When a highly-trained super spy wakes up with amnesia, on a boat in the middle of the sea, he begins the process of discovering his true identity. But the process is complicated, when he’s chased by stealthy assassins, and must risk his life. He runs from the assassins, darting across Europe with a beautiful female companion. In the end, he discovers that he is actually one of these assassins himself, but decides to run away, and give up killing forever.

Now that that’s out of the way, you can start trimming. Read the clunky, awkward sentences above like an encrypted prison letter. There’s valuable stuff in there, if you can just find it. Scan for hero, antagonist, conflict and irony and cut everything else.

That leaves “highly trained super spy,” “stealthy assassins,” “chased by…” and the irony is essentially Bourne’s amnesia.

Don’t be afraid to leave out any details other than those specified above. All effective log lines omit story details. In the Bourne log line, for instance, we don’t need to mention Europe, the female companion, or the end of the story. Log lines are about brevity and subtlety. The power comes from how quickly and effectively you can communicate your idea.

Take a second pass at the log line now, trying to include only the elements you scanned for after the first pass. Maybe you’ll come up with something like this:

When a highly trained super spy with amnesia is hunted by stealthy assassins, he has to stay alive long enough to figure out who he is.

Clearly, this isn’t eloquent writing. Right now, you’re just getting your ideas out. Block out your filter. Ignore that voice screaming that “THAT SENTENCE IS TERRIBLE AND CONFUSING!” Remain patient as you polish – the end result will be worth it.

Time for another pass. This time, try to mold these elements with a little more grace. Cut unnecessary words, and make sure your details are accurate, informative and essential.

The first thing I’d cut is “when.” This is a mistake that lots of first time writers make. “When” is an unnecessary word. If you cut it, you’ll throw your reader into the meat of your concept more quickly. The ‘when’ is implied.

Next, look at how you’ve defined your hero. “Highly trained super spy.” That’s actually not too bad. But it’s a little redundant. Cut ‘super’ and the log line will work better.

Continue to scour the log line for small redundancies. Play around with the order of the words. Make sure that all of the essential elements are clearly defined and prominent in the log line.

You’ll end up with something like this…

A highly trained spy wakes up with amnesia and must determine his true identity before he’s killed by government assassins.

This log line is short and powerful. Notice the presence of all the necessary elements:

hero – a highly trained spy

antagonist – government assassins

conflict – evading the assassins, figuring out true identity

irony – a super spy with amnesia

Also take notice of the adjectives we’ve used. They were carefully selected to communicate as much as possible about the story in very few words.

Finally, this log line clearly indicates audience and cost. Because it is a slim, trim story description, it’s clear that this is a standard ‘genre’ piece. It’s an action thriller. The demographic is clear. The cost can certainly vary, but could be ball-parked pretty accurately based on similar movies in the genre.

Although this process isn’t the most glamorous part of screenwriting, it’s immensely satisfying. Log lines are hugely important to screenwriters. Yes – of course it’s possible to write without one, but we don’t advise it.

Why deny yourself the joy of a tight, compact concept? As you form your outline and write your draft, you’ll find yourself referring back to the log line over and over again. It keeps you on track and will save you weeks – maybe months – of rewriting in the future.

  1. Thanks for this. One question:

    Does the log line give away the resolution. In the example “before he’s killed by government assassins.”, it tells the reader what happens to the protagonist. Is this normal? Or should one avoid revealing too much?

    1. Don’t worry about giving away too much. Your goal with the log line is to get people to read your entire screenplay – I don’t care what you have to give away, just make sure they want to read your screenplay after reading your log line.
