The pilot decides whether there is a season
The pilot is the first episode of a series. For an adaptation, it is also the episode that turns your book into television for the first time. Buyers read the pilot script, or watch the pilot, to decide whether they want more. Viewers watch it to decide whether to keep going. Either way, the pilot has one job above all others: make people want episode two.
Adapting a novel makes that job harder in a particular way. Novels are allowed to start slowly. A reader who has bought the book will give it 30 or 50 pages to get going. A viewer will not give a pilot 30 minutes. If your book's inciting incident, the event that starts the main plot, arrives in chapter 9, the pilot cannot simply film chapters 1 to 9 in order and hope for the best.
This planner takes the pilot's length, its structure and the position of your inciting incident in the book, and produces a minute-by-minute timeline. It tells you where each act ends, the exact minute the inciting incident should land, which chapters the pilot covers, how much screen time each setup chapter gets, and what the pilot must establish before it ends.
Acts on television, explained plainly
An act is a block of an episode that ends on a turn: a reveal, a threat or a decision that changes direction. Most television writers plan episodes in acts, and the reason goes back to advertising.
Ad-supported television
On ad-supported television, the episode stops for commercial breaks. Each act ends just before a break, so writers end every act on a moment strong enough to bring viewers back after the advertisements. The number of acts follows the number of breaks the network schedules.
Common patterns, as rules of thumb:
- One-hour drama. A teaser (a cold open) followed by four, five or six acts. Older network dramas often used four acts; many later shows moved to five or six as advertising breaks increased.
- Half-hour comedy. A cold open followed by two or three acts, sometimes with a short closing scene called a tag.
A one-hour slot on ad-supported US television holds roughly 42 to 44 minutes of story; a half-hour slot holds roughly 21 to 22. The exact figure depends on the network, so ask for its format before you write.
Streaming
Streaming services without advertising do not stop the episode. There are no required act breaks, and episode lengths vary from one episode to the next. Many writers still plan streaming episodes in acts, usually three to five, because act endings are where the story turns. Some streaming scripts mark acts on the page and some do not. The structure is a tool for pacing, not a rule from the platform.
What this means for your choice
If you know the pilot is for ad-supported television, pick the act count the network uses, often five or six for an hour. If it is for streaming, or you do not know yet, four acts is a sensible planning default. You can always merge or split acts later; the minute positions of the key beats will move only slightly.
What a cold open does
A cold open is a short scene that plays before the opening titles. Its job is to hook the viewer at once, before the episode has introduced anyone properly. A cold open can be a moment of danger, a strange discovery, a joke, or a flash-forward to something dramatic later in the story.
The planner sizes the cold open as a share of the episode, which varies by genre:
| Genre | Cold open share | In a 45-minute pilot |
|---|---|---|
| Comedy | 6% | 3 minutes |
| Drama | 8% | 4 minutes |
| Crime / procedural | 8% | 4 minutes |
| Fantasy / science fiction | 8% | 4 minutes |
| Romance | 8% | 4 minutes |
| Thriller | 10% | about 5 minutes |
The result is rounded to the nearest whole minute and kept between 1 and 7 minutes. These shares are planning defaults drawn from common practice, not a rule. A comedy cold open is often a single quick joke; a thriller cold open is often a complete tense scene.
For an adaptation, the cold open is also a fix for slow openings. If your book's first chapters are quiet, the cold open can show a moment from later in the book, then cut back to the beginning. Viewers then watch the setup knowing where it leads.
How the planner builds the timeline
The calculation is short enough to follow by hand.
- Cold open. Multiply the pilot length by the genre's share, round to a whole minute, and keep it between 1 and 7. If you choose no cold open, this is zero.
- Act length. Subtract the cold open from the pilot length and divide by the number of acts. The planner gives every act the same length so the arithmetic is clear. Real acts vary by a minute or two.
- End of act one. Cold open plus one act length. This is where the inciting incident lands, unless it happens in chapter 1.
- Chapter-one inciting incidents. If the main plot starts in chapter 1, the incident lands at the end of the cold open, or halfway through act one if there is no cold open.
- Act breaks. Each later act ends one act length after the previous one. The break nearest the middle of the episode is marked as the midpoint.
- End-of-pilot hook. The final two minutes, or the final minute for pilots of 22 minutes or less.
- Chapters covered. From chapter 1 through the inciting chapter, plus about 5% of the book's chapters (at least one more chapter), so the pilot ends on the first consequence of the event.
Worked example: a 45-minute drama pilot
Take an illustrative drama with 30 chapters whose inciting incident happens in chapter 3. The pilot is 45 minutes, opens with a cold open and is planned in four acts. These are the tool's default answers.
Cold open. 45 times 8% is 3.6 minutes, which rounds to 4 minutes.
Act length. 45 minus 4 leaves 41 minutes. Divided by four acts, each act runs 10.25 minutes, shown as 10:15.
Inciting incident. The end of act one is 4 plus 10.25, which is 14.25 minutes, shown as 14:15. That is where chapter 3's event should land.
Other act breaks. Act two ends at 24:30, which is the midpoint of the four acts. Act three ends at 34:45. Act four runs to the end.
End-of-pilot hook. The last two minutes, starting at 43:00.
Chapters covered. Five percent of 30 chapters is 1.5, which rounds to 2. Chapter 3 plus 2 more gives chapters 1 to 5, about 17% of the book.
Setup time. Two chapters come before the inciting incident. They share 14.25 minutes of screen time, which gives about 7.1 minutes each, shown as 7:08.
Chapter 3 is 10% of the way through the book, well inside the planner's limit of 15%, so the result is a pass. The pilot can tell the story in order, open with a cold open taken from chapter 2 or a flash-forward, and reach the main plot at 14:15.
The 15% and 30% limits
The verdict depends on how far into the book the inciting incident sits, measured as the inciting chapter divided by the total number of chapters.
| Inciting incident position | Verdict | What to do |
|---|---|---|
| 15% or earlier | Pass | Tell the setup in order and reach the event at the end of act one |
| Over 15% up to 30% | Warning | Compress the setup chapters to the scenes the event depends on |
| Over 30% | Fail | Move the event earlier on screen, or open on it and go back in time |
These limits are this planner's rules, based on common screenwriting guidance that the event starting the main plot should arrive within roughly the first quarter of a story. Feature screenwriting manuals often place it around page 10 to 15 of a 100- to 120-page script. A pilot has the same need, with even less patience from its audience.
Example: a late inciting incident
Consider an illustrative thriller with 30 chapters whose main plot starts in chapter 7. The pilot runs 60 minutes, has no cold open and is planned in five acts.
With no cold open, each act is 60 divided by 5, which is 12:00. The end of act one, and the inciting incident, falls at 12:00. Chapter 7 of 30 is about 23% of the way in, so the planner gives a warning.
Six chapters of setup now share twelve minutes, about 2:00 each. That is enough for one short scene per chapter, often less. The pilot covers chapters 1 to 9 (chapter 7 plus 2 more). The practical fix is to read chapters 1 to 6 and list only the scenes chapter 7 depends on: the people the event happens to, the place it happens, the thing they lose. Everything else moves to later episodes, appears in flashback, or is cut.
The five acts in this example also bring a timing pattern. Act two ends at 24:00, act three at 36:00 (marked as the midpoint), and act four at 48:00, when the final act begins to play out the first consequence of the event. The hook starts at 58:00.
Example: an inciting incident too late for the pilot
Now an illustrative fantasy whose main plot begins in chapter 12 of 30, 40% of the way through the book. A 45-minute pilot with a cold open still reaches the end of act one at 14:15. Eleven chapters of setup cannot fit there in any useful form. The planner fails the plan.
There are two common solutions. The first is to move the event: show it at the end of act one even though it happens later in the book, and fold the most important setup material into later episodes. The second is to open on it: use the cold open to show the event, or the moment just before it, then cut back to the lead's ordinary life and catch up. Either way, the viewer knows by the end of act one what the series is about.
Half-hour pilots
Half-hour pilots move faster and use fewer acts. Take an illustrative comedy with 24 chapters whose inciting incident is in chapter 2. The pilot runs 22 minutes with a cold open and three acts.
Comedy's 6% share of 22 minutes is 1.32, which rounds to a 1-minute cold open. That leaves 21 minutes for three acts of 7:00 each. Act one ends, and the inciting incident lands, at 8:00. The end-of-pilot hook is only one minute long because the pilot is 22 minutes or less, so it starts at 21:00. The pilot covers chapters 1 to 3.
In comedy, the inciting incident is often the event that creates the series' situation: the move to a new town, the new job, the unlikely roommate. The checklist item for comedy asks for the situation that will keep producing jokes every week. A pilot that is funny once but sets up no repeatable situation does not sell a series.
The checklist: what every pilot must establish
The checklist in the results lists seven things the pilot has to put on screen. Two are checked automatically when your plan already meets them. The rest are for you to plan into the outline.
- The inciting incident lands by the end of act one. Checked when the event sits within the first 15% of the book.
- A cold open hooks the viewer. Checked if you chose one. It is optional on streaming and common on ad-supported television.
- The lead, and what they want, by the end of the first scene. Viewers need someone to follow and a reason to follow them.
- The opposing force is on screen. A person, a system or a deadline. It can be brief, but it must be seen.
- The genre item. For drama, the web of family, work or friends the series will return to. For thrillers, the threat or deadline, shown rather than described. For comedy, the repeatable situation. For crime and procedural shows, one case opened and closed in the episode plus the season-long mystery. For fantasy and science fiction, one rule of the world shown in action. For romance, the two leads together and the obstacle between them.
- The season's question in one sentence. If you cannot say it, the pilot will not make it clear.
- An ending that makes viewers start episode two. The last one or two minutes, ending on a question, not an answer.
Writing the end-of-pilot hook
The hook is the last one or two minutes before the credits. It decides whether a viewer presses play on episode two, and whether a buyer asks for more scripts. Four kinds of ending work well for adapted pilots:
- A reveal. Something the lead or the audience believed turns out to be false. The body in the lake is not who everyone thought.
- A threat arriving. The opposing force makes its first direct move against the lead, and the episode cuts away before we see the result.
- A decision. The lead chooses something they cannot take back: they take the job, sign the confession, open the door.
- An arrival. A new person walks in who changes everything, often someone the book introduces a few chapters after the pilot's range ends.
Look at the last chapter in the pilot's range for one of these. If it ends quietly, borrow the strongest moment from the next chapter or two and end the pilot there. That is why the planner's chapter range runs a little past the inciting incident: it gives you material for the hook.
Avoid ending on a summary, a reflection or a quiet conversation that settles the episode's tension. Those scenes work at the end of a chapter in a novel, where the reader has already committed to the book. On screen, they give the viewer permission to stop.
Pilots for limited and ongoing series
The planner's timeline works for both kinds of series, but the pilot's ending carries a different weight in each.
In a limited series, the whole season is one story with a fixed end. The pilot's job is to set up that one story clearly: who the lead is, what the central question is and why it matters by the final episode. The hook should point toward that final answer.
In an ongoing series, the pilot must also show that the show can keep going. Buyers ask what episode 20 looks like. A procedural shows this with the case of the week; a family drama shows it with a web of relationships that will keep producing conflict; a fantasy shows it with a world large enough to explore for years. Make sure the pilot shows the repeatable part, not only the first chapter of a single story.
If you do not yet know which kind of series your book should be, the movie or TV series decider scores both against the shape of the book.
Counting the characters
Novels often introduce a dozen named people in their first few chapters. A pilot cannot. Viewers need time to learn faces, names and relationships, and each new person costs screen time.
The planner suggests that a pilot can introduce about six to eight people clearly. That is a rule of thumb, not a limit, but it is a useful test. Count the named characters in the chapters the pilot covers. If there are fifteen, decide which ones the season depends on, introduce them now, and hold the others back for later episodes.
For an adaptation, this often means a character who appears early in the book is introduced later on screen, or two minor characters are merged into one.
From timeline to script pages
A common rule of thumb in screenwriting is that one page of a correctly formatted script runs about one minute on screen. A 45-minute pilot is usually written at about 45 to 60 pages, depending on how much is dialogue and how much is action. Half-hour comedy scripts vary more, because some comedy formats space the page out differently.
Use the minute marks from the timeline to set page targets. In the 45-minute drama example, the cold open runs about 4 pages, act one ends around page 14, the midpoint around page 24 or 25, and the hook starts around page 43. If your draft reaches the inciting incident on page 25, you know before anyone else reads it that act one is running long.
Building the pilot outline step by step
- Run the planner and note the chapter range, the act breaks and the inciting incident minute.
- Read the chapters in the range and list every scene, with one line for what happens.
- Mark the scenes the inciting incident depends on. Those stay.
- Mark scenes that introduce characters or places needed in the first season. Keep those if there is time.
- Cross out the rest, or move them to a list for later episodes.
- Put the kept scenes into the act blocks. Each act should end on the turn the timeline asks for.
- Choose the cold open last: the most gripping moment that does not give away the ending of the season.
- Write the hook: the last scene before the credits should raise a question the next episode will answer.
When you can read your outline aloud in about five minutes and every act ends on a turn, you are ready to write pages.
Common mistakes in adapted pilots
Filming the first chapters in order. Novels often open with setup. Television needs the main plot to start by the end of act one. Compress, reorder or open on the event.
Explaining the world instead of showing it. Fantasy and science fiction books often open with history or rules. On screen, show one rule in action and let viewers learn the rest as they go.
Ending the pilot on a resolution. A pilot that ties everything up gives viewers no reason to watch episode two. Resolve the episode's small problem if you like, but end on the big open question.
Too many people. If the pilot needs a cast list to follow, cut or delay characters.
Leaving the opposing force off screen. A villain who is only mentioned is easy to forget. Give them at least one scene, or one clear sign of their presence.
