How to Write a Short Film Script

A short is not a small feature

The most common short film mistake is a feature premise squeezed into ten minutes: too many characters, too much backstory, an ending that arrives before the story has started. A short works best around one idea and one turn — a single situation that changes once, decisively.

Finding an idea that fits

Good short film ideas tend to be:

• A moment, not a saga — one evening, one conversation, one decision.
• Contained — one or two locations, two or three characters.
• Built around a reveal or a reversal — the thing we learn at the end reframes everything before it.

The logline test still applies: if you cannot say it in a sentence, it is probably too big.

Structure

Shorts compress three acts into a handful of pages:

1. Hook (first page). Drop us into the situation. No establishing walk to the front door.
2. Complication (the middle). One obstacle or escalation.
3. Turn and out (the last page or two). The reversal lands — and the film ends. Shorts are weakened more by lingering endings than by abrupt ones.

Start late, leave early applies to every scene, and to the film as a whole.

Write what you can shoot

On a short, the script is the budget. Every location is a permit and a company move; every extra is a costume and a meal; night exteriors and moving vehicles are expensive. None of that means writing small ideas — it means expressing them through what is cheap to shoot: faces, a single room, a phone.

Mistakes programmers see constantly

• Opening with an alarm clock or a character waking up.
• A twist that depends on withholding obvious information rather than a genuine reframing.
• Dialogue that explains the backstory instead of letting the situation show it.
• Running long. A 20-minute short competes with ten 2-minute shorts for the same programme slot.

Writing one

Shorts use standard screenplay format. ScenePaper's free Writers' Room has a Short Film template to start from, and when the script is done the same project carries through to breakdown, scheduling and call sheets — useful when the writer is also the producer, as on most shorts.
