How to Write a Short Film: Idea to Script in 6 Steps

Most first short film scripts are a feature squeezed into a few minutes: too many characters, too many places, and an ending that explains itself. We followed One More Day, a 5:38 short by M.E. Owens from the Summer 2026 Flick Residency, from its premise to the lines its characters speak, using the character notes, numbered shot notes and dialogue saved on its public canvas. This guide shows how to write a short film in six steps, each with the film's real words and the writing rule behind them.

How do you write a short film, step by step?

1. Step 1

   Shrink the idea

   Cut the idea down to one person who wants one thing badly, with a clock on it, because a short has room for one change and not a subplot.

   • One More Day in a sentence: after a car crash leaves her in a coma, Vivi meets Death, who offers her one more day.
   • The want is in the title, and so is the clock.
   • Test yours as a logline: who, what they want, and what stands in the way, in under 30 words.

2. Step 2

   Write the characters

   Before any scene, write each character as appearance, personality and backstory, so every line and action later has something true to come from.

   • M.E. Owens wrote one note per character, with headed sections.
   • Death's note adds a fourth section, Role in the Story: "her bubbly personality even on death's doorstep makes him curious."
   • That one line is the engine of the film: Death bends a rule because of who Vivi is.

   

   # Character: Vivi Lovell
   
   ## Appearance
   Early twenties, pale skin, bright blue eyes, black hair pulled into two messy buns. She wears a worn denim jacket over a casual top, slim jeans, and dark sneakers. Her style is effortlessly relaxed — like someone who threw on whatever felt comfortable but somehow always looks put-together.
   
   ## Personality
   Normally lively and bubbly — the kind of person who lights up a room without trying. She's warm, a little chaotic, and deeply loyal to the people she loves. She laughs easily and talks with her hands. People are drawn to her energy.
   
   ## Backstory
   Vivi was involved in a devastating car accident alongside her parents. She was the only survivor, but she never woke up. She now lies in a coma, has for 5 months— her body still, her world somewhere unreachable. The tragedy is that the girl everyone remembers as full of life is frozen somewhere between here and gone. She can see everything happening around her, her soul outside of her body.

3. Step 3

   Shape three movements

   Give the story a beginning that sets up a normal world, a turn that breaks it, and an end where the character chooses, because a short film has time for exactly one arc.

   • Beginning: Vivi and her parents joke about her coffee order on a morning drive, until the crash.
   • Turn: Death asks, "You want one more day?", and then she learns what it cost: "You... You killed someone?"
   • End: at her parents' grave, she tells Death, "I'm ready."

4. Step 4

   List the scenes

   Write a numbered list of scenes, each with a place, a time of day and what happens, before writing any dialogue, so you can see the whole film on one page.

   • One More Day's notes are numbered this way: Shot 1 is the country highway in the morning, Shot 3 is the crash.
   • Each note holds the action, the sound and the one line spoken.
   • Cut any scene whose job another scene already does.

   

   # Shot 3: Interior Family Car — The Crash
   
   Sunlight dances through the windshield. The radio hums. Then a violent horn blast shatters the calm. A truck's headlights suddenly fill the windshield, swerving across the center line. The steering wheel jerks. Brakes scream. Glass explodes. Metal twists. The world spins.
   
   FATHER: "Hold on!"
   
   Cut to black. Silence. Then a single crow caws in the dark.

5. Step 5

   Write the subtext

   Let characters talk about something small while the scene is about something big, because an audience leans in to work out what is really being said.

   • On the surface, the family argues about a coffee order.
   • Underneath, it is a scene about choosing, minutes before Vivi loses the chance.
   • "It's not a life-changing decision" is a joke until the next scene.

   00:15

   Starting Inside the car @Shot 2 - Interior Family Car, Repositioned, soft music hums through the speakers. Vivi (22), @Vivi Lovell bright blue eyes and black hair in two messy buns, sits in the back seat with a paper coffee menu unfolded in her lap. Her mother glances warmly at her through the rearview mirror. Her father grins from the driver's seat. Soft natural window light, warm and intimate framing.
   
   MOTHER: "Still haven't decided?"
   VIVI: "I have. I'm just making sure it's the right choice." in Vivi's voice @Maya's Warning Label.
   FATHER: "It's not a life-changing decision."

6. Step 6

   Pay off the setup

   End on an image or line that answers something from the first scene, so the ending lands without anyone explaining it.

   • The coffee order from the car comes back at the grave.
   • Vivi sets down a mug and says the line the whole film has been waiting for.
   • The prompt marks the change in four words: "This time, VIVI ... isn't crying."

   00:12

   In the cemetery referencing @Lovell Family Grave at Dusk, the wind stirs the grass. Golden light washes over the cemetery. This time, VIVI @Vivi Lovell Character Sheet isn't crying. First: Shot open on a medium shot of Vivi's back as she kneels before her parents' grave holding the coffee mug with coffee in it from @Frame at 11.0s. Cut to close up on Vivi's hands as she places the mug @Frame at 11.0s at her parents' grave. Cut to close up on Vivi's face as she smiles.
   She speaks in the voice referencing @Maya's Warning Label : "I finally decided what to order."
   A soft laugh escapes her. She brushes her fingers across the headstone.

   Open the One More Day workflow

What makes a short film script work?

1. 1. Start late, leave early

   Open each scene as close to its turn as you can and cut out as soon as it lands, as One More Day's crash ends on a crow caw in the dark.

2. 2. Return to a place

   Bring the character back to a location to show the change, as Vivi kneels at her parents' grave in tears, then comes back to it smiling.

3. 3. Write what the camera sees

   Keep action lines to what can be seen and heard, in short present-tense sentences like "Brakes scream. Glass explodes. Metal twists." instead of explaining feelings.

4. 4. Give a force a signature

   Tie a sound or image to your antagonist, as Death's note says a flock of crows always comes before him, so later scenes can play the crows alone.

5. 5. Make a line do two jobs

   Let one line carry both a joke and a character, as Vivi greets Death with "You really need a warning label", bubbly even on death's doorstep.

6. 6. Read it out loud

   Read every line aloud, or hear it in a generated voice, because dialogue that looks fine on the page often sounds stiff once someone speaks it.
