10 Great Sci-Fi Movies Not Based On Books


  • Great sci-fi movies not based on books showcase the original storytelling abilities of filmmakers, like George Lucas with Star Wars.
  • These movies, such as Avatar and Donnie Darko, draw inspiration from various sources but are not direct adaptations of any singular book.
  • Directors like Christopher Nolan with Inception and the Wachowskis with The Matrix, create unique and innovative sci-fi films that stand on their own, revolutionizing visual effects and storytelling.



Great sci-fi movies not based on books showcase the abilities of filmmakers and screenwriters alike. Audiences may be surprised at which of their favorite sci-fi films weren’t lifted from the pages of any existing books. Though the clever concepts and believable world-building of certain films make them seem like book adaptations, film writers and directors have historically crafted original stories at par with the greatest sci-fi books of all time.

While sci-fi films based on books deal with the pressures of properly honoring the source material, movies with completely original screenplays face a different challenge. Science fiction movies have been around for over a century, and nearly every viable sci-fi concept has been explored and remixed to no end, making any original screenplay a rare storytelling gem. This isn’t to say that great sci-fi movies not based on books don’t borrow from literature in some way – this is inevitable for any modern artwork. Even though they’re inspired by the long history of literary and cinematic sci-fi storytelling, these movies have achieved greatness without directly lifting from any book’s pages.

George Lucas drew inspiration from various sources – including mythology, classic literature, and old serials – to flesh out the Star Wars movies. However, Star Wars is not directly based on any literary work. The saga’s foundation emerged from Lucas’s original screenplay, evolving as he developed the narrative. While there are Star Wars books, they came after the films. Lucas prioritized visual storytelling, crafting a space opera that transcended traditional literary adaptations. The iconic characters, like Luke Skywalker and Darth Vader, sprang from his imagination – not pre-existing written works. Star Wars is a cinematic journey born from Lucas’ vision, and is not a direct translation of any singular book.

While Avatar‘s story bears resemblance to films like Fern Gully and Pocahontas, James Cameron conceived the plot and wrote the screenplay himself. The film’s narrative and the world of Pandora were products of Cameron’s imagination, blending elements of environmentalism, indigenous cultures, and science fiction. Unlike adaptations from pre-existing literature, Cameron crafted Avatar’s universe to fit the visual medium of film. While there are tie-in novels and comics, they serve to expand the lore rather than being the source material. The creation of the Na’vi, the conflict with the humans, and the exploration of Pandora all originated from Cameron’s blockbuster-driven approach to storytelling.

The story of Donnie’s encounters with a mysterious figure named Frank, time travel, and existential themes were crafted specifically for the screen. While there’s a novelization of the movie, it was released after the film’s debut and serves as an extension rather than source material. Donnie Darko‘s enigmatic plot and characters are a testament to Kelly’s original storytelling, not an adaptation of pre-existing literary work.

Director Christopher Nolan also wrote the screenplay for Inception, which is not an adaptation of any existing literary work. The intricate narrative, centered around the concept of dream infiltration and manipulation, emerged from Nolan’s distinct storytelling style. Alongside the plot’s “snowballing effect,” the film’s exploration of dreams within dreams and the complexity of the human mind is a product of the writer-director’s creative vision. While there are books and theories on dreams and the subconscious, Nolan crafted the mind-bending cinematic experience independently. With its iconic, action-driven take on exploring the different layers of dreaming, Inception is an original and innovative addition to contemporary science fiction cinema.

  • Cast: Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss
  • Runtime: 136 minutes

Was The Matrix inspired by Grant Morrison’s Invisibles? Morrison has famously argued this to be the case, as there are many similarities between The Matrix and The Invisibles. However, the Wachowskis have maintained that their film’s groundbreaking concept of a simulated reality built by artificial intelligence is their original work. Moreover, the rumors about copies of The Invisibles being used as a reference during The Matrix‘s filming have been unfounded. At the same time, the Wachowskis drew inspiration from various sources, blending cyberpunk aesthetics, martial arts, and philosophical sci-fi – not unlike The Invisibles. Technically, The Matrix isn’t an adaptation, but an original film that revolutionized visual effects and storytelling.

Even though The Fifth Element may seem like it was pulled directly from a classic sci-fi book or comic, director and writer Luc Besson crafted the movie’s screenplay on his own. The vibrant world, unique characters like Leeloo and Korben Dallas, and the overarching quest to save the universe are original elements of Besson’s imagination. While Besson drew inspiration from various sources, including French sci-fi/fantasy comics, The Fifth Element stands as a cinematic original, not a direct adaptation.
