Before a single episode gets shot, before a pilot script is ordered, a network or streaming executive reads your bible. That document — typically 15 to 30 pages — has one job: make someone who reads dozens of pitches a week believe your show deserves to exist for five seasons.
The format has evolved considerably over the past decade. Streaming platforms want longer arcs and cleaner mythology documents. Broadcast still prizes economy. Cable sits somewhere between. But the core sections remain consistent across every tier of the industry, and the writers who get their bibles right share a few structural habits that the rest don't.
This guide breaks down every mandatory section, gives you a working template, and walks through what the publicly known bibles or pitch documents for seven major shows got right — so you can reverse-engineer their approach for your own project. For a deeper look at the underlying format conventions, see our guide on breaking down the anatomy of a television script.
A TV show bible (also called a series bible, pitch document, or show document) is the foundational written reference for a television series. It exists to answer two questions simultaneously: What is this show? and Why will audiences watch it for years?
The bible serves different audiences at different stages. During pitching, it sells the executive. Once the show is greenlit, it becomes a writers' room reference document — the authoritative guide to tone, character, and mythology. A bible that only serves one of those purposes is a weak bible.
Length varies by market:
A bible is not a pilot script. Some pitches include a pilot script alongside the bible; others lead with the bible and attach the script later. In 2026, most streaming platforms want the bible first.
The logline is one to two sentences. It names the protagonist, their situation, their goal, and the central conflict. The premise section expands this into a paragraph or two — enough to establish the hook without over-explaining.
The premise must answer: What is the engine that drives new stories every week? A drama about a corrupt detective is a character. A drama about a corrupt detective who must solve a murder that he himself committed — without being exposed — is a premise with an engine. Every episode can turn on that tension.
Write your logline before anything else. If you cannot summarize the show in two sentences, the concept is not clear enough yet.
This section establishes the physical and social environment the show inhabits. It is not a geography lesson — it is a tone document. The world section tells the reader what it feels like to be inside this show.
Describe the primary locations and why they matter dramatically. A hospital drama is not set in a hospital — it is set in a pressure cooker where life-and-death decisions happen every hour. A suburban comedy is not set in a suburb — it is set in a place where everyone performs normalcy while quietly falling apart.
For genre shows, this section also establishes the rules. If your show involves time travel, the world section defines how time travel works, what it costs, and what it cannot do. Readers need to know the rules before they can evaluate the stories.
Most bibles present 4–8 series regulars. Each character gets half a page to a full page covering:
Do not write character descriptions that sound like a casting breakdown. "Charming, mid-30s, hides her pain behind wit" is a costume, not a character. Show the contradiction. Show the wound. Show what story only this person can tell.
This section is often one page and is frequently underwritten. It should answer:
Tone comparisons ("It's The Wire meets The Office") are a double-edged tool. They help a reader orient quickly, but they invite the executive to compare your show to better-known properties. Use them carefully and only when the comparison is genuinely accurate.
This is the section that separates writers who understand television from writers who understand films. A season arc is not just "what happens" — it is the structural spine that holds episodic stories together and escalates toward a season finale that changes the world of the show.
For a serialized drama, map the season in three movements: the first third (establish the status quo and introduce the central threat), the second third (complications, reversals, raising of stakes), the final third (convergence toward the breaking point and aftermath). You do not need to break every episode — you need to prove the arc has shape.
Also address, briefly, what Seasons 2 and 3 look like. Executives are buying a business, not a story. They want to know the mythology scales.
One to two pages summarizing the pilot episode in prose. This is not a synopsis of a script you have already written — it is a persuasive document that makes the executive want to read that script. Write it with the narrative urgency of a short story. Hit the inciting incident, the first-act break, the midpoint revelation, and the ending hook.
The pilot summary should demonstrate that you know how to structure an episode while also establishing character efficiently. Every major character should appear and want something, even in summary form.
Beyond the pilot, you need to show that the engine generates stories. Present three to five additional episode concepts as one-paragraph rundowns. These do not need to be fully worked out — they need to prove the premise keeps producing conflict.
Each rundown should contain: the A-story premise, which character it centers on, and the emotional or thematic question it explores. If every episode sounds like a variation of the same story, your premise may be too narrow. If every episode sounds completely unrelated, your premise may lack focus.
Use the following order as your default. It is not the only valid sequence, but it matches reader expectations and front-loads the material that gets bibles thrown out or passed up the chain.
Keep the document visually clean. Use headers, modest white space, and a readable font (12pt Courier or 11pt Helvetica/Arial). Avoid production photos, heavy graphics, or mood boards unless you are pitching to a company that specifically requests them.
Note: What follows is based on publicly documented information about these shows and their creators' publicly stated development approaches. None of the original pitch documents are available publicly in authenticated form, and we are not claiming to reproduce them.
Vince Gilligan has discussed the Breaking Bad pitch extensively in interviews. The central logline — "Mr. Chips becomes Scarface" — is one of the most quoted in the industry because it does everything a logline should do: it names the transformation arc, the starting point, and the ending point in five words. The premise was character-driven and concept-simple, which made it easy to pitch verbally. Gilligan spent more document real estate on Walter White's psychology than on plot. That prioritization was correct. The show ran on character, not on procedural mechanics.
What to steal: Lead with the transformation arc, not the plot. One sentence should name who your protagonist is becoming.
Lost was developed under extreme time pressure — ABC requested the pilot very quickly — and the mythology document was necessarily incomplete at the outset. What exists in the public record suggests the bible leaned heavily on mystery and premise over resolved answers. The show's writers have acknowledged in interviews that some mythology questions in the early bible were never fully answered. The lesson here is dual: strong mythology documents generate buzz, but promises you make on the page must be payable. If your bible establishes a central mystery, at least privately know the answer before you commit it to paper.
What to steal: A mythology bible should establish the central question with precision. The answer can evolve; the question must be stable.
David Simon came to The Wire from journalism, and the bible reportedly read more like a sociological argument than a conventional pitch document. Each season was framed around a different institution — the drug trade, the docks, the school system, the newspaper. The bible's intelligence was in treating each season as a self-contained argument while the characters provided continuity. This is a particularly useful model for shows with a strong thematic thesis.
What to steal: If your show has a structural intelligence beyond character — a thesis about how systems work — lead with that thesis. It distinguishes the show from anything that can be reduced to a simple logline.
Phoebe Waller-Bridge developed Fleabag as a one-woman stage show before it became a television series. The bible that pitched the television version had a structural advantage: the character was already proven. For a single-POV show driven by a specific, distinctive voice, the most persuasive thing you can put in a bible is a pages-long extract of that voice. The tone document essentially wrote itself because the protagonist's voice was so distinctive that no comparisons were needed.
What to steal: If your show's differentiating factor is voice rather than concept, demonstrate that voice in the bible itself — not just in the pilot summary.
Jesse Armstrong's Succession is one of the clearest examples of a show where the character section carried the pitch. The Roy family's internal dynamics — each sibling's specific wound, specific strategy, and specific blind spot — were sufficiently distinctive that the premise (who will inherit a media empire) became almost secondary. The show generated story from character chemistry, not from external plot mechanics. The bible probably devoted more space to character than to season arc.
What to steal: In an ensemble drama, character relationships are the engine. Map the specific tensions between characters, not just the tensions within them.
Dan Erickson's Severance sold on premise clarity. The central concept — employees undergo a procedure that completely separates their work and personal memories — is so clean and so philosophically loaded that it generates immediate story questions without requiring explanation. The bible's world section would have needed to do significant work establishing the rules of "severance" and the corporate culture of Lumon Industries. Shows with high-concept premises must over-invest in the world section.
What to steal: High-concept premises require airtight rules. Define what the concept can do, what it cannot do, and what happens when those limits are tested — all before you get to characters.
Christopher Storer's The Bear is a useful model for contained, atmosphere-driven dramas. The show's bible would have needed to convey an almost sensory experience — the heat and noise of a professional kitchen — through prose alone. In a setting-driven show, the world section is essentially the show's emotional argument. Storer's background in comedy gave the show a specific comic pressure valve that had to be captured in the tone section; without that, the show reads as unrelenting grimness.
What to steal: Tone is not a genre label. Describe the emotional texture of a specific episode moment — what a scene in your show feels like at its best.
Once your bible is polished, getting professional feedback on the underlying script can identify structural issues before you enter the room. AIScriptReader's screenplay feedback service and screenplay coverage can surface character and premise weaknesses that are easier to address before the pitch than after.
For broadcast network pitches, 10–20 pages is standard. For premium cable and streaming, 20–35 pages is more typical, especially if the show has significant mythology. A limited series bible can be shorter. If you are consistently over 40 pages, you are probably over-explaining.
Not always, but it helps significantly. Most streaming platforms and cable networks want to see the pilot script alongside the bible at the point of a formal pitch. In a general meeting or early conversation, the bible alone may be sufficient to generate interest. Verify the specific submission requirements of each company before submitting.
Directly to major networks and streaming platforms, it is very difficult without representation or a producing attachment. However, production companies, independent studios, and competitions (such as the WGA's programs or network diversity initiatives) accept direct submissions. An agent or manager is not required to develop a bible; it is required to get it in front of the right doors efficiently.
The terms are often used interchangeably. Strictly speaking, a pitch document is what you bring to a meeting — it may be shorter and more sales-focused. A bible is the fuller reference document that also serves the writers' room. In practice, most writers develop one document that performs both functions.
Focus on 4–8 series regulars. Introduce recurring characters only if they are essential to understanding the premise or pilot. Introducing too many characters in the bible dilutes focus and signals to the reader that you have not yet identified who the show is really about.
