A sci-fi short film typically runs 5-18 pages and is defined by concept-driven short films that explore a single speculative idea with precision and humanity. sci-fi shorts distill complex themes into crystalline narrative experiments.
One idea, explored thoroughly. The best sci-fi shorts are thought experiments: 'What if one thing about reality were different?' World-building should be implied through production design notes and character behavior, never explained through dialogue. The protagonist's relationship to the technology or concept is the story. Keep the cast small and the location contained — the concept provides the scope. Hard sci-fi concepts can work in short form because you only need to sustain the logic for 10 pages. The ending should deliver the idea's most surprising or devastating implication.
Introduce the concept through a character experiencing it (1-3 pages). Explore the concept's implications through one scenario (3-10 pages). Deliver the twist or thematic payoff that reveals the concept's true meaning (1-3 pages). Total: 5-18 pages. Festival-ideal: 8-15 pages.
Define your one big idea — the single speculative element that makes your world different from ours.
Build the world through character experience, not exposition. Let the audience discover the rules alongside the protagonist.
Ground the speculative concept in a deeply human story. Strip away the sci-fi and the emotional core should still work.
Create a glossary for yourself but keep jargon to a minimum in the script. If a reader has to pause to decode terminology, you've lost them.
