The DNA of a film's narrative begins with the screenplay, but the starting point varies wildly between these two disciplines. Original screenplays are born from a blank page and a writer's imagination, while adapted screenplays involve the complex art of translating existing stories—from novels to news articles—into a visual format that honors the source while standing on its own.
Highlights
Original screenplays are the birthplace of entirely new cinematic universes.
Adapting a 'true story' still requires significant fictionalization for dramatic pacing.
The most successful adaptations often diverge significantly from their source material.
Writing a sequel is legally and artistically classified as an adaptation of the first film.
What is Original Screenplays?
Scripts written for the screen that are not based on previously published or produced material.
Provide writers with total creative sovereignty over characters, plot, and world-building.
Must establish a completely new internal logic and mythology within the first act.
Are eligible for specific 'Best Original Screenplay' categories at major award shows.
Often serve as 'spec scripts' used by writers to showcase their unique voice to studios.
Can become 'intellectual property' (IP) that eventually gets adapted into other media like books.
What is Adapted Screenplays?
Scripts derived from existing sources such as books, plays, articles, or even other films.
Sequels and prequels are technically categorized as adaptations because they use existing characters.
The writer must often 'kill their darlings' by cutting beloved book scenes to fit a film's runtime.
Require legal acquisition of 'option rights' before a studio can begin the writing process.
Can be based on non-fiction sources, including historical records or long-form journalism.
The Academy considers any script based on characters already established in another medium as adapted.

Detailed Comparison
The Challenge of the Blank Page
Writing an original screenplay is an exercise in pure invention. Without a safety net of existing lore, the writer is responsible for every nuance of the dialogue and every beat of the plot, ensuring they are both cohesive and compelling. This freedom is exhilarating but carries the heavy burden of having to prove the story's worth and logic to an audience from second one.
The Art of Translation
Adaptation is less about copying and more about translation. A novelist might spend fifty pages describing a character's internal monologue, but a screenwriter must find a way to convey that same depth through a single visual action or a line of subtext. The goal is to capture the 'spirit' of the source material while acknowledging that cinema is a fundamentally different medium with its own rhythmic demands.
Marketability and Risk
In modern Hollywood, adapted screenplays are often viewed as 'safer' investments because they come with a built-in audience and a proven concept. Original screenplays are seen as higher risk but offer the potential for much higher rewards; they are the primary source of 'cult classics' and groundbreaking new genres that eventually become the franchises of the future.
Structural Differences
Original scripts are usually built around the 'Three Act Structure' specifically designed for a two-hour experience. Adapted scripts often have to wrestle with structures that weren't meant for film—like the meandering pace of a 600-page novel or the single-room constraints of a stage play. The screenwriter’s job is to restructure these stories into a cinematic shape without losing the essence that made the original popular.

Common Misconceptions
Myth
Adapted screenplays are easier to write because the story is already done.
Reality
In many ways, they are harder. Writers must dismantle a functioning story and rebuild it for a different medium, which often requires more technical skill than starting fresh.
Myth
A 'faithful' adaptation is always the best version.
Reality
Literal translations from book to screen often feel stiff or boring. The best adaptations, like 'The Shining' or 'Jurassic Park,' make massive changes to suit the visual nature of film.
Myth
Original screenplays can't be based on real life.
Reality
They can be inspired by real events or people, but if they aren't based on a specific published account (like a book or article), they are still considered original.
Myth
Sequels are original screenplays because the specific plot is new.
Reality
Because sequels use 'pre-existing characters' and worlds, award bodies and guilds almost always classify them as adapted material.
Frequently Asked Questions
What counts as 'previously published material' for an adaptation?
This includes books, plays, short stories, magazine articles, and even blog posts or viral social media threads. If the core narrative or characters existed in a public format before the script was written, it is an adaptation.
Can a movie be both original and adapted?
Not for the purposes of awards or legal filing. A script must fall into one category. However, a writer might 'adapt' their own original, unpublished play into a screenplay, which would still technically be an adapted screenplay.
Why are some biopics considered original and others adapted?
It depends on the source. If the writer researched the person’s life using various public records and interviews, it’s original. If they bought the rights to a specific biography and used that as their primary roadmap, it becomes an adapted screenplay.
Which category wins more Oscars?
Historically, the split is fairly even, as the Academy values both the invention of the new and the skillful transformation of the old. However, Best Picture winners are slightly more likely to be adapted screenplays due to the industry's preference for established IP.
What is an 'option' in screenwriting?
An option is a legal agreement where a producer pays a fee to the owner of a book or story for the exclusive right to develop it into a film for a set period (usually 12–18 months). If they don't make the movie, the rights return to the original owner.
How do writers handle long books like 'Dune' or 'Lord of the Rings'?
They usually identify a 'central dramatic question' and cut anything that doesn't answer it. This often means combining two characters into one, cutting subplots entirely, or ending the film halfway through the book to create a sequel.
Do authors of the original books have a say in the screenplay?
Usually, no. Unless the author is a massive star like J.K. Rowling, they typically sell their 'dramatic rights' and lose all creative control over the film version. Some are hired to consult, but the director and screenwriter have the final word.
What is a 'Spec Script'?
A spec script is an original screenplay written 'on speculation'—meaning the writer wasn't paid to do it and doesn't have a buyer yet. It is the most common way for new writers to break into the industry.
Verdict
Choose an original screenplay when you want to experience a fresh, unpredictable voice and a story that was designed specifically for the camera. Look toward adapted screenplays when you want to see a beloved world reimagined or a complex true story distilled into a powerful, focused narrative.
