Original Pilot or Spec Episode: Which Writing Sample Are You Being Asked For?

Two writers can answer the same request — "send us a spec" — and send scripts that have almost nothing in common.

One sends a pilot for a series she made up. The world is hers, the characters are hers, and nobody asked her to write it. The other sends an episode of a show that already exists, using its characters, its format, and its rules, also written without anyone asking. Both scripts are uncommissioned. Both might get called a spec. If you are the writer receiving that request, the word alone has not told you which object is wanted, and finishing the wrong one costs weeks you could have spent on the right one.

The fix is not to find a better synonym. It is to notice that the word is doing two different jobs, and separate them.

Two questions, not one

A script can be described along two independent axes.

Whose world is it? An original pilot belongs to a series world the writer created. A sample episode of an existing series belongs to somebody else's show — you are writing inside a world with established characters, a house style, and rules you did not set.

How did it come about? Either you wrote it on your own initiative, or you wrote it because someone asked you to. A commission is the paid version of that second case: a buyer engages you for a script. But "someone asked" is broader than "someone is paying." A program might ask you to submit an original pilot with your application. That request doesn't make the world anyone else's and doesn't make the script a commission.

Put the two questions together and you get four plain categories:

Now look at what "spec" does. In one common usage, it tells you about the first axis's right-hand side only in the negative: an episode written inside somebody else's show. In another, it tells you about the second axis: nobody asked for this. It usually comes from speculative — written on the speculation that someone will want it — but the word has spread until it gets attached to the object in some conversations and to the arrangement in others.

In a 2020 episode of the Scriptnotes podcast, "Should You Pitch or Spec That?", the working screenwriters talking there draw exactly this distinction between an existing-show writing sample and independently written material intended for sale. That is a useful record of how practitioners use the term. It is not a standard, not a rule about what you are permitted to send, and not a survey of what anyone wants now. Even where it settles the vocabulary, it settles nothing about your particular recipient. That person's own words still decide, and you can usually read them.

Say what the script is, not what it's called

The practical move is to stop saying "my spec" and describe the object.

If the world is yours: an original pilot written independently.

If the world is theirs: an independently written sample episode of [name of the series].

Both labels answer the two questions at once. A recipient sorting through material can tell in one line whose show they are about to read and whether anyone commissioned it. You also protect yourself from a more serious error. An existing-show sample is not a series you own, and it is not a proposal for a new show. Sending it as though it were a pitch for your own project misdescribes the material, and the script's first page will correct the misdescription immediately.

The reverse is worth saying too. A commissioned episode of an existing show — a script you were hired to write for production — is not the uncommissioned sample this distinction concerns. You may later show it as a sample of your work, and produced episodes are often used that way, but the object itself is a deliverable. Whatever comes with it, including deadlines, drafts, notes, and who owns what, belongs to that arrangement rather than to this distinction.

Three requests, read closely

Here are three invented request emails, written to make the categories visible. They are teaching examples, not real opportunities, and none of them is permission to send anything to anyone.

1. "For the next stage, please send a completed original pilot."

• Object: one complete pilot script.
• World: the writer's own.
• Assignment: none. The writer created this.

A one-sentence reply: "Attached is Harbor Line, a complete original pilot written on my own initiative."

2. "Send a sample episode you wrote independently for an existing series."

• Object: one episode script.
• World: an existing show — not the writer's.
• Assignment: none. The email says so out loud, which is unusually helpful.

Reply: "Attached is an independently written sample episode of [series]; it was not commissioned by the production."

Notice that this request is the one where the word "spec" would be a fair shorthand, and the writer who was told "send a spec" and heard "send a pilot" would have prepared the wrong object entirely.

3. "Deliver the episode commissioned under our writing assignment."

• Object: one episode script.
• World: the existing show.
• Assignment: yes — someone asked, engaged, and is expecting delivery.

This request has the same object shape as the second one: an episode of an existing series. It has the opposite assignment status. If you had labeled the material by its object alone — "an episode of [series]" — you would have been half right and missed the half that matters, because this one was not written as a sample and is not a spec of any kind. The email is about work in progress, not about a demonstration of ability.

That third example is the reason the existing-show label can't be trusted to imply "spec" on its own. An episode of someone else's show is a spec only when nobody commissioned it.

Now the variant that causes the trouble. Suppose the first email actually reads: "Send us your spec." What is missing?

• Whether the script should be an original pilot or a sample episode of an existing series.
• What this stage wants: the complete script, or something shorter first. "Spec" implies a script; it says nothing about how much of one is wanted now.
• Where and how to send it.

Three gaps, and guessing fills none of them reliably.

What the request is for, and what stage it's at

Purpose is a legitimate clue. Three purposes come up often.

Someone may want to hear your original voice — how you build a world and write people when the choices are yours. That points toward original material.

Someone may want to see whether you can write inside an established show — whether you can pick up its rhythms, respect its format, and produce something that sounds like the show rather than like you visiting it. That points toward a sample episode.

Someone may be considering a proposed new series, in which case what's in view is your project, and the materials that accompany it may not be a full script at this stage at all.

These purposes help you interpret a vague request. They do not override a clear one. If the email says "sample episode of an existing series," the purpose you inferred is irrelevant; the email said what it said.

The stage matters just as much. "Send a spec" does not tell you that a finished pilot is required. Early conversations frequently want a logline, a paragraph, or a one-page description of a project, and asking a first-time writer to spend two months on a pilot when the request was for a page of prose is a real cost. Check what this stage asks for. If a program, a representative, or a recipient has published instructions, those instructions decide — and you should read the current version rather than last year's, because requirements change and old advice circulates long after it stops being accurate.

When the request is ambiguous, ask

If the object isn't clear, the answer is a short question, not a stronger guess. Something as plain as:

"Happy to send it — should this be an original pilot or a sample episode of an existing series, and do you want the full script at this stage?"

That is one sentence, it names both readings, and it lets the recipient answer in a few words. It also spares you the worst outcome available here: submitting the wrong object confidently.

Two things this vocabulary does not do. It does not tell you which of your scripts is stronger — that is a separate judgment about selection, made after you know what kind of object is wanted. And it does not grant you access to anyone. Learning that "spec" has two meanings does not make unsolicited material welcome; whether you may send work, to whom, and through what route is its own question with its own answer, sometimes "no." Read the actual submission instructions, ask the person who invited you, and treat the vocabulary as description rather than permission. Questions about using an existing show's characters and world belong to that same separate territory, where the answers aren't writing advice.

Describe the material accurately

When you reply, use a sentence that states the object, the world, and the assignment status. Then say how it matches what was asked. If it doesn't match — if you have an original pilot and the request was for an existing-show sample — say that instead of relabeling. Relabeling is the failure this whole distinction exists to prevent. Calling a pilot "an episode" to make it fit changes nothing on the page, and the recipient reads the page next.

The full version of that sentence is usually two clauses long. "Here is Harbor Line, an original pilot written independently; it is complete and runs to the length you asked for." Or: "Here is an independently written sample episode of [series]; it was not commissioned by the production." Either one tells the reader exactly what they are about to open, which is all the label is for.

If a detail is still unresolved — whether they want a full script at this stage, or which of the two readings they intended — name it in the reply or ask it before you send. A precise object label and one honest question is a complete answer to a request that never quite said what it wanted.

Frequently asked questions

What two independent questions separate an original pilot from a sample episode?

First, whose world is it: a series world the writer created, or an existing show with established characters and rules? Second, how did the script come about: written on the writer's own initiative, or requested or assigned? Combining them gives four categories, including an uncommissioned original pilot, a requested pilot for the writer's own project, an independently written sample episode of an existing series, and a commissioned episode of that show.

Why is the word 'spec' unreliable on its own?

One common use means an episode written inside somebody else's show. Another use means nobody asked for it, from the idea of writing on speculation. A 2020 episode of the Scriptnotes podcast records working screenwriters drawing that distinction between an existing-show sample and independently written material, but that is a record of usage, not a standard, rule, or survey. Even where it settles vocabulary, it does not decide what a particular recipient wants.

How should a writer describe the script when replying?

State the object, the world, and the assignment status. For the writer's own world: an original pilot written independently. For an existing show: an independently written sample episode of [series], with a note that it was not commissioned. Then say how it matches what was asked. If it does not match, say so rather than relabeling; calling a pilot an episode changes nothing on the page.

What gaps can remain in a request that only says 'send us your spec'?

It may not say whether the script should be an original pilot or a sample episode of an existing series. It may not say what this stage wants: a complete script, or something shorter first. It may not say where or how to send it. A short question naming both readings and the stage is more reliable than guessing.

Does learning the vocabulary give permission to submit material?

No. Learning that 'spec' has two meanings does not make unsolicited material welcome. Whether a writer may send work, to whom, and through what route is a separate question, and the answer is sometimes no. Read the actual submission instructions, ask the person who invited the writer, and treat the vocabulary as description rather than permission. Questions about using an existing show's characters and world are also separate from writing advice.
