Would your book make a good movie?

Visible conflict, a clear goal, a deadline, a one-sentence premise and a producible scale decide whether a book works on screen.

A book makes good movie material when its conflict can be seen, the lead wants something specific, a deadline forces action, and the premise fits in one sentence. Stories told mostly through thoughts, with huge casts or heavy effects, are harder to film. This checklist scores six areas out of 100 and names the three weakest.

What "movie material" actually means

When people say a book is movie material, they rarely mean that it is good. Plenty of excellent novels would make poor films, and some ordinary novels make very good ones. What they mean is that the story already has the features a screen version depends on: conflict you can watch, a lead who wants something, pressure that forces action, a premise someone can grasp in a sentence, a scale a production can afford, and an audience that already cares.

This self-assessment scores your book on those six areas. You answer nine questions. Each answer is worth a fixed number of points, the points add up to a score out of 100, and the results show exactly where every point came from. The tool then names your three weakest areas, gives a specific fix for each, and suggests the format the book suits best.

Nothing in the score is hidden. The full rubric is set out below so you can check the arithmetic, disagree with a weighting, or score the book by hand.

The scoring rubric

Six areas add up to 100 points.

Area Maximum What earns the points
Visible conflict 20 Conflict that a camera can show
Goal and deadline 20 A clear goal (12) and a deadline (8)
Story told in action 15 A small share of the story told through thoughts
One-sentence premise 15 A premise you can pitch in one sentence
Producible scale 15 Locations (5), cast (5) and effects (5)
Existing readers 15 Proof that people already want the story

The weights reflect how much each area tends to matter when someone reads a book with adaptation in mind. Story areas carry 70 of the 100 points. Cost and audience carry 30. That balance is deliberate: a story that works on screen can usually find a budget and an audience, but a story that does not work on screen rarely gets fixed by either.

Visible conflict: 20 points

Your answer Points
Mostly visible, physical conflict 20
A mix of visible and inner conflict 13
Mostly inner conflict 5

Screen stories are told through what people do and say. A chase, an argument, a trial, a negotiation or a fight can be filmed directly. A character's struggle with grief, guilt or doubt has to be turned into something visible before it can be filmed. That is possible, and great films do it, but it takes more work and more skill, which is why inner conflict earns fewer points here.

Goal and deadline: 20 points

A clear goal earns 12 points: the lead wants something specific, and the reader knows what it is early in the book. A deadline earns 8 more: a date, a countdown, or an event that will happen whether or not the lead is ready.

The goal gives the audience something to follow. The deadline gives the story speed. Without a deadline, a lead can take as long as the writer likes, and screen stories that drift lose viewers. With one, every scene either moves the lead toward the goal before time runs out or it does not belong.

Story told in action: 15 points

Share of the story told through thoughts Points
20% or less 15
21% to 35% 11
36% to 50% 7
51% to 70% 3
Over 70% 0

This is your estimate of how much of the book happens inside a character's head rather than in action or dialogue. It is the area most authors underestimate. Novels can spend pages on what a character remembers, notices or feels. Film can show some of that through performance, a little through voice-over, and the rest has to be converted into scenes.

If you are unsure, skim three chapters from different parts of the book and mark each paragraph as action, dialogue or thought. The share of thought paragraphs is a fair estimate.

One-sentence premise: 15 points

If you can state the premise in one sentence that makes people want to see it, the book earns 15 points. If not, it earns 5.

A premise sentence like this is often called a logline (a one-sentence summary of the story). It names the lead, what they want, what stands in the way, and what happens if they fail. Buyers, agents and producers read many projects. A premise they can understand and repeat in a sentence is far easier for them to champion. A book whose appeal can only be explained in a paragraph is harder to sell, even if the book is very good.

Producible scale: 15 points

Three parts, five points each:

Part 5 points 3 points 1 point
Key locations 10 or fewer 11 to 20 Over 20
Important speaking parts 12 or fewer 13 to 25 Over 25
Special effects and spectacle None Some Heavy

Locations cost money because each one needs to be found or built, lit and moved to. Speaking parts cost money because each one needs to be cast and paid. Effects cost money because invented creatures, worlds and battles need specialist work. None of these stop a book being adapted. They change how much it costs and, as a result, which buyers can afford it and which format suits it.

Existing readers: 15 points

Your answer Points
Not published yet 3
Published, with a small readership 7
Steady sales or a series with a following 11
Bestseller or a large, measurable following 15

Readers reduce the buyer's risk. An adaptation of a book people already love has an audience waiting. This area carries only 15 points because readership is not the same as suitability: strong stories with few readers do get adapted, sometimes first as short films or lower-budget projects.

Reading the verdict

Score Verdict What it means
75 to 100 Strong film material Most of what a screen version needs is already there
55 to 74 Promising, with fixable gaps The core works, but the weak areas would come up in the first meeting
Under 55 Not film-ready as written The story depends on things a camera cannot show easily, or the pitch is not yet clear

These bands are this tool's own thresholds. They are meant as a guide to where to spend your effort, not as a prediction of whether the book will be adapted.

Worked example: the default answers

Take an illustrative novel with these answers, which are the tool's defaults: a mix of visible and inner conflict, a clear goal but no deadline, about 30% of the story told through thoughts, a one-sentence premise, 8 key locations, 10 important speaking parts, no special effects, and a published book with a small readership.

Work through the rubric:

  1. Visible conflict. A mix earns 13 of 20.
  2. Goal and deadline. A clear goal earns 12; no deadline earns 0. Total 12 of 20.
  3. Story told in action. 30% falls in the 21% to 35% band: 11 of 15.
  4. One-sentence premise. Yes: 15 of 15.
  5. Producible scale. 8 locations earns 5, 10 speaking parts earns 5, no effects earns 5. Total 15 of 15.
  6. Existing readers. Published with a small readership: 7 of 15.

The total is 13 + 12 + 11 + 15 + 15 + 7 = 73 out of 100. That falls in the 55 to 74 band, so the verdict is "Promising, with fixable gaps".

Finding the three weakest areas

The tool ranks areas by the share of their maximum they earned, not by raw points, so a 15-point area and a 20-point area can be compared fairly.

  • Existing readers: 7 of 15 is 47%.
  • Goal and deadline: 12 of 20 is 60%.
  • Visible conflict: 13 of 20 is 65%.
  • Story told in action: 11 of 15 is 73%.
  • Premise and scale: 100% each.

So the three weakest are readers, goal and deadline, and visible conflict, in that order. Areas with full marks are never listed as weak. If fewer than three areas lost points, the tool lists only those and suggests working on pitch documents instead.

The fixes for this example

For existing readers, the fix is to gather proof: review counts, ratings, sales rank history and mailing list size, presented as numbers rather than adjectives.

For goal and deadline, the lead already has a goal, so the fix is the deadline: decide what happens if the lead fails by a specific day, and show that date on screen by the end of the first act.

For visible conflict, the fix is to give the inner struggle a person, an object or a place. If the lead is fighting guilt, put the person they wronged in the room.

Make the deadline change in your adaptation plan, not necessarily in the novel. A screen version can add a deadline that the book handles more loosely.

Three more examples

A contained thriller

An illustrative thriller with visible conflict, a clear goal, a deadline, 10% told in thoughts, a strong premise, 6 locations, 8 speaking parts, no effects and steady sales. The score is 20 + 20 + 15 + 15 + 15 + 11 = 96. Only readership lost points, so it is the only weak area listed. The best format is a feature film.

A quiet literary novel

An illustrative literary novel with mostly inner conflict, a clear goal but no deadline, 60% told in thoughts, no one-sentence premise, 9 locations, 7 speaking parts, no effects and a small readership. The score is 5 + 12 + 3 + 5 + 15 + 7 = 47, under 55.

The three weakest areas are story told in action (3 of 15, or 20%), visible conflict (5 of 20, or 25%) and the premise (5 of 15, or 33%). The suggested format is a limited series, because a book told largely through inner life needs the extra time a series gives each character.

A score of 47 does not mean this book cannot be adapted. Novels like it have become admired films and series. It means the adaptation will need more invention, and the pitch must explain how the inner story becomes visible.

An epic fantasy with a huge cast

An illustrative fantasy, not yet published, with mixed conflict, a clear goal, a deadline, 25% in thoughts, a strong premise, 30 locations, 40 speaking parts and heavy effects. The score is 13 + 20 + 11 + 15 + 3 + 3 = 65, promising with gaps. Scale earns only 3 of 15 because every part of it scores the minimum.

The best format is an ongoing series: heavy effects together with more than 25 speaking parts or more than 20 locations point to a world too large for one film or one season.

How the format suggestion works

The tool checks four rules in order and stops at the first that matches.

  1. Ongoing series. Heavy effects, plus more than 25 speaking parts or more than 20 locations.
  2. Limited series. More than 12 speaking parts, more than 15 locations, or more than half the story told in thoughts.
  3. Short film or micro-drama. Not yet published, no special effects, and 6 or fewer speaking parts. A small, contained story with no readership yet suits a low-cost proof of concept.
  4. Feature film. Everything else.

This is a quick rule set. For a fuller comparison that also weighs word count, viewpoint characters, subplots, time span, series size, genre and ending, use the movie or TV series decider.

Fixing each area in practice

Raising the visible conflict score

Go through the book and list every important inner struggle. For each one, ask what a person could do on camera that shows it. Fear can become avoiding a room. Guilt can become a phone call the character keeps not making. Resentment can become an argument about something small. Each answer is a scene the adaptation can use.

Adding a deadline

Ask what happens if the lead does nothing. If the answer is "nothing much", invent or sharpen a consequence and tie it to a date: the hearing on Friday, the wedding in three weeks, the eviction at the end of the month. Then put that date on screen early.

Reducing the inner story

Take the chapters heaviest in thought. For each one, write a single line of action or dialogue that carries the same feeling. The resulting list becomes your scene outline, and the share of the story told through thoughts drops.

Writing the premise sentence

Fill in this pattern: when something happens, a specific person must do something difficult, or else a clear consequence follows. Keep it under 35 words. Read it to someone who has not read the book. If they ask a question about the story, the sentence is working; if they ask what you mean, rewrite it.

Bringing the scale down

Merge characters who do the same job in the story. Move scenes into fewer places. List every effects shot and keep only the ones the plot depends on. The goal is not to make the book small, but to make the first screen version affordable.

Proving readership

Collect the numbers you have: reviews, ratings, sales over time, newsletter subscribers, reader messages, book club adoptions. Put them on one page. Numbers persuade buyers; adjectives do not.

How genres tend to answer the questions

Genre does not enter the score directly, but it shapes the answers. The patterns below describe typical books in each genre, not rules. Your book may differ, and the score follows your answers, not your genre label.

Thrillers and crime novels usually answer well on visible conflict, goal and deadline, because the form is built on a threat and a race against time. Where they lose points is scale: a thriller that moves across six countries collects more than 20 locations quickly.

Romance often has a clear goal and a premise that fits in a sentence, but much of the story may be told through each lead's feelings. Look hard at the share of the story told in thoughts, and at whether the obstacle between the leads can be shown rather than felt.

Fantasy and science fiction frequently score well on conflict and premise and poorly on scale. Invented worlds need effects, and large casts are common. That is why the format rules point big fantasy worlds toward an ongoing series.

Literary fiction tends to lose points on visible conflict and inner story, and sometimes on the premise sentence. It often gains on scale, because many literary novels take place in a few rooms with a small cast. A low score here is common and does not rule out a strong adaptation; it signals where the work lies.

Horror usually has visible threat and a small, contained setting, which helps both conflict and scale. Watch the effects answer: a creature that must look real on screen moves the book from none to some or heavy.

Memoir and narrative non-fiction often lack a single goal and deadline because real life rarely provides them. An adaptation usually picks one period of the subject's life that does have a clear goal and a ticking clock, and builds the screen story around that.

The questions buyers ask, area by area

Each area in the rubric matches a question that tends to come up early when a producer or development executive reads a book for adaptation. Preparing a clear answer to each is a practical way to use the score.

Area The question you will hear A good answer looks like
Visible conflict What do we actually see happen? Three or four scenes described as actions, not feelings
Goal and deadline What does the lead want, and why now? One sentence for the goal, one for the deadline
Story told in action How do we show what is in her head? Named scenes that replace the key inner passages
One-sentence premise What is it about? A logline under 35 words
Producible scale What does it cost to make? Location count, cast count and a short effects list
Existing readers Who already wants this? Sales, reviews and subscriber numbers on one page

If you cannot answer one of these questions in a sentence or two, that area is weak whatever the score says. If you can, write the answers down and keep them with your pitch documents.

Scoring a book by hand

If you want to score a book without the tool, or check its result, use this order:

  1. Write down the conflict answer and its points: 20, 13 or 5.
  2. Add 12 if the lead has a clear goal shown early, and 8 if there is a deadline.
  3. Estimate the share told in thoughts and look up its points: 15, 11, 7, 3 or 0.
  4. Add 15 for a one-sentence premise, or 5 if you do not have one yet.
  5. Score locations, speaking parts and effects at 5, 3 or 1 each, and add them.
  6. Add the readership points: 3, 7, 11 or 15.
  7. Add everything up. Compare the total with the bands: 75 and over, 55 to 74, under 55.
  8. Divide each area's points by its maximum and list the three lowest percentages. Those are your weakest areas.

The tool does exactly these steps. Doing them once by hand is a good way to see which single answer would move your score the most.

What the score cannot tell you

Rights. Before you pitch, check who owns the film and television rights. Your publishing contract may have granted them to the publisher, or a producer may hold an option. A film or series based on a book is a derivative work, and only the rights holder can authorise one. This page is not legal advice; have an entertainment lawyer review any option or rights agreement before you sign it.

Timing and fashion. What buyers want changes from year to year. A book that scores 70 may sell quickly because its subject is in demand; a book that scores 90 may wait.

The people involved. A committed producer, director or actor can carry a lower-scoring book into production. The score measures the story, not the team.

Quality of writing. The score does not read your prose. It measures structure and scale, which is what an adaptation keeps.

Using the score well

Score the book honestly first. Then make the fixes in your adaptation plan, your logline and your pitch documents, and score the book again as the screen version you intend to make. The difference between the two scores shows how much adaptation work the book needs, and the fixes list shows where that work lies.

Keep both scores. The first tells you about the novel. The second tells you about the pitch.

Questions authors ask

What makes a book good movie material?
Conflict you can see, a lead who wants something specific, a deadline that forces action and a premise that fits in one sentence. Producers also weigh cost, which rises with the number of locations, speaking parts and effects, and they look for proof that readers already care.
Can a book told mostly through thoughts still be adapted?
Yes, but it takes more work. The adaptation must turn thoughts into actions, dialogue or images, and sometimes uses voice-over. Books like this often suit a limited series, which has the time to let a character’s inner life show through behaviour.
How is the score calculated?
Six areas add up to 100: visible conflict 20, goal and deadline 20, story told in action 15, one-sentence premise 15, producible scale 15 and existing readers 15. Each answer adds a fixed number of points, shown in the breakdown, so you can see exactly where the score comes from.
Does a low score mean my book will never be adapted?
No. The score measures how ready the story is for the screen today, not its quality as a book. Many of the gaps, like a missing deadline or premise sentence, can be fixed in the adaptation and the pitch without changing the novel.
Why does readership count?
Buyers look for proof that people already want the story. Sales, reviews and a mailing list lower their risk. It is only 15 of the 100 points, because a strong story with few readers can still get made, especially as a short film or a lower-budget feature.
