Screenwriting for Founders
What a Script Actually Is
Most people think scripts are stories written down. They're instructions for building something.

A screenplay is not a novel with dialogue. It is a technical document that tells a director, cinematographer, production designer, and actors exactly what they will see and hear. Every line you write translates to screen time, crew hours, and budget. Writers who forget this produce scripts that cannot be made.
The format exists for a reason that has nothing to do with tradition. One page of properly formatted screenplay equals roughly one minute of screen time. This ratio lets producers estimate shooting schedules and budgets by page count. When you write action as "The city awakens" instead of describing what the camera actually captures, you break the tool that the entire production uses to plan.
Screenplays operate under constraints novels do not face. You cannot write a character's internal thoughts unless they are spoken aloud or shown through action. You cannot describe a feeling the audience will have. You can only write what a camera can record and a microphone can capture. This limitation is not a weakness—it forces clarity.
The industry standard is 90-120 pages for a feature film. Anything under 90 pages reads as incomplete. Anything over 120 pages signals a first-time writer who does not understand pace. These are not arbitrary numbers—they map to theatrical release windows, audience attention spans, and the economics of distribution.
Professional readers spend three to five pages deciding whether to keep reading. They are looking for proper formatting, clear scene construction, and dialogue that sounds like people actually speak. If your script violates any of these in the opening pages, it goes in the pass pile regardless of your story. The reader has thirty scripts on their desk and a deadline.
Understanding what a script is means accepting what it is not. It is not a literary artifact. It is not a final product. It is a blueprint that will be interpreted by dozens of people before an audience sees a frame. Write for those interpreters first, the audience second.
Every word you write costs someone else's time and money to execute.

TERMS
The header at the start of every scene indicating location and time of day, formatted as INT. or EXT., location name, and DAY or NIGHT. This tells the production team where to shoot and what lighting setup they need. Every time you change location or time, you need a new slugline—missing one creates ambiguity that costs production time.
The prose between dialogue that describes what happens on screen, written in present tense and limited to what can be seen or heard. This is where you control pacing—short sentences create urgency, longer ones slow down. Action lines that run more than four lines without a break make readers skip ahead.
A brief direction in dialogue indicating how a line is delivered, placed in parentheses under the character name. Use them rarely—actors and directors consider excessive parentheticals insulting. Only include them when the meaning of the dialogue is unclear without the direction.
A screenplay written without payment or commission, speculating that it will sell. Spec scripts are written to be read, not shot, which means they can break some formatting rules for readability—but they must never break the fundamental ones. Most professional writers started with a spec that got them representation.
A pause in dialogue or action, usually written as (beat) in parentheticals or as "A beat." in action lines. Beats control rhythm and give actors space to react. Overusing them makes your script feel slow. A beat should only appear when the silence matters.
A sequence of brief scenes showing the passage of time or connected actions, formatted as a series of short sluglines or as a single montage block. Montages compress time efficiently but should be used sparingly—they are easy to write and hard to make interesting. If your montage runs longer than a page, it is probably not a montage.
