What is a spec script?

By the WriteLoom editorial teamUpdated 2026-09-02
Key facts
  • A spec script is written without a commission, on the writer's own time and risk.
  • Feature specs are original stories; TV specs can be original pilots or episodes of existing shows.
  • Most spec scripts sell nothing but get the writer meetings and assignments.
  • Original pilots have largely replaced episode specs as TV writing samples.
  • A spec is a writing sample first and a sale prospect second.
Direct answer

A spec script is a screenplay written without payment or commission, on speculation that it will sell or open doors. Most specs never sell. Their real function is as a writing sample: proof you can structure a story, write dialogue, and finish, which is what gets a writer meetings and assignments.

Chapter i·Why it matters

Understanding the spec's real job changes what you write. If a spec is a lottery ticket you chase trends. If it is a sample you write the thing only you could write, in the genre you want to be hired in, at a budget level someone could plausibly make. That second framing produces more careers.

Chapter ii·What to include

  • A genre and tone you want to be hired to write more of.
  • A budget that is realistic for a first sale, which usually means contained.
  • A complete, polished draft rather than an interesting first act.
  • A logline that survives being said out loud at a party.
  • Coverage or notes from readers who do not owe you kindness.
  • A second script, because one sample is rarely enough.

Chapter iii·Example

A writer's contained thriller spec never sold, but it got her a general meeting that led to a paid rewrite assignment on a studio project. The script did its job; it just was not the job she thought it had.
