We talk a lot about books becoming movies. But the reverse — movies you didn’t know became books — is a long, strange, and often surprisingly literary tradition. From a Star Wars novelization that hit shelves six months before the film to a Tarantino debut novel that hit #1 on the NYT bestseller list, these ten examples show how the page and the screen have always fed each other in both directions.
The traffic between Hollywood and publishing has always moved in both directions, but most people only notice one lane. Books get optioned, adapted, and turned into blockbusters.
That part everybody knows. What gets less attention is the other direction: movies you didn’t know became books. And not just rushed tie-ins dashed off to cash in on a film’s opening weekend — though some of those exist too — but genuine literary works, Hugo Award-winning authors, and in at least one case, a writing collaboration so complex that both men ended up credited on the book and the screenplay in opposite orders.
The phenomenon has a name: novelization. It covers a spectrum from the shoddy to the sublime. At its worst, a novelization is a verbatim transcription of a screenplay with thin prose smeared between the dialogue. At its best, it’s something that makes you understand the source story differently — expanding character psychology, restoring deleted scenes, or giving a visual spectacle an inner life the screen can never quite provide.
This list covers ten films, ranked by how surprising or culturally significant the movie-to-book leap turns out to be, and every entry here is factually verified. No invented publications, no misattributed authors.
Here, then, are ten movies you didn’t know became books.

Movies You Didn’t Know Became Books
10. Pan’s Labyrinth (2006)
The book: Pan’s Labyrinth: The Labyrinth of the Faun (2019) by Guillermo del Toro and Cornelia Funke
The film needs no introduction — Guillermo del Toro’s Spanish Civil War fairy tale is one of the most visually arresting films of the 21st century. What fewer people know is that thirteen years after the film’s release, del Toro approached German fantasy author Cornelia Funke (Inkheart) to co-author a novelization.
Her response, as she described on her website, was essentially: how do you say no to a task that feels impossible? The collaboration produced a dark fantasy novel that didn’t merely transcribe the film but expanded its world, added ten original fairy tales into the narrative structure, and recast the ending in ways that shifted the story’s moral weight. The book became a New York Times bestseller.
It was also the first major book Funke wrote in English. Del Toro has since done the same with The Shape of Water — so this appears to be a genuine creative interest of his, not just a licensing exercise.
9. The Abyss (1989)
The book: The Abyss (1989) by Orson Scott Card
James Cameron’s underwater science fiction film about a deep-sea drilling crew and first contact with non-terrestrial intelligence was one of the most ambitious productions of its decade.
For the novelization, Cameron brought in Orson Scott Card — who at the time was already the only author to have won both the Hugo and Nebula Awards in consecutive years (for Ender’s Game and Speaker for the Dead). This wasn’t a writer-for-hire doing a quick turnaround.
Card was given access to the film’s set and actors during production, and Cameron reportedly had the lead actors read Card’s character background material — written before the film was finished — to better understand their roles. The result was a novelization widely praised for standing on its own as a thriller.
Unlike most tie-ins, this one stayed in print considerably longer than average.
8. Once Upon a Time in Hollywood (2019)
The book: Once Upon a Time in Hollywood: A Novel (2021) by Quentin Tarantino
This one is worth knowing about if only for what it represents: Quentin Tarantino’s debut as a novelist, published two years after the film’s release. He didn’t simply write the movie as a book.
As Tarantino described in interviews with Deadline, he had accumulated years’ worth of character backstory, deleted scenes, and material he’d written purely to understand the characters — content that was never going to make it into the film. The novel deploys all of it. The timeline is rearranged. Cliff Booth’s backstory gets several dedicated chapters. The film’s finale appears near the beginning rather than the end.
Tarantino called it “a complete rethinking of the entire story,” and the Washington Post described it as “a distinct experience — rangier, sexier, bloodier” than the film. It debuted at number one on the New York Times fiction bestseller list.
Tarantino said in that interview that his love for the novelization format goes back to his teenage years, when movie tie-in paperbacks were the first adult books he read.
7. Poltergeist (1982)
The book: Poltergeist (1982) by James Kahn
The origin story here is frankly wonderful. James Kahn was working as an emergency room doctor in Santa Monica when he was called to the set of E.T. the Extra-Terrestrial to assist with a scene involving the alien’s resuscitation. He gave Spielberg a copy of his science fiction novel. That conversation led, within days, to an offer: novelize Poltergeist, then in post-production, in under a month.
Kahn accepted, took a month off from his ER shifts, holed up in Spielberg’s office on the MGM lot, and wrote longhand for fifteen hours a day.
The book expands significantly on the character of Tangina — the paranormal specialist who appears only at the end of the film — giving her dream sequences and an astral confrontation with the entity that didn’t make it onto the screen. It remains a genuinely hard-to-find collector’s item and, among readers who’ve tracked it down, a respected addition to the Poltergeist mythology.
6. Alien (1979)
The book: Alien (1979) by Alan Dean Foster
Alan Dean Foster is the undisputed master of the movie novelization, having written tie-ins for Star Wars, Alien, Aliens, and Alien 3, among dozens of others.
The Alien novelization, published the same year as Ridley Scott’s film, was based on Dan O’Bannon’s screenplay — but written before all of the film’s visual design decisions had been finalized. This means, famously, that the xenomorph receives almost no physical description, because H.R. Giger’s creature design came to life after the screenplay was locked.
What the book does provide is interior life — character thoughts, backstory, and the famous “eggmorphing” sequence that was cut from the film (later restored in the Director’s Cut).
Foster’s version of Ellen Ripley is noticeably more developed psychologically than she appears in the final edit of the film. For fans who want to understand what the writers were thinking before the cinematography took over, this is the entry point.
5. The Omen (1976)
The book: The Omen (1976) by David Seltzer
Here’s a case where the person who wrote the screenplay also wrote the novel — and the novel landed on bookshelves two weeks before the film opened.
David Seltzer, the screenwriter, adapted his own script, and the result was one of the bestselling books of 1976. The novelization sold three and a half million copies in paperback — a figure that, per multiple publishing sources, was unprecedented at the time for a tie-in.
The book makes changes worth noting: character names differ (Robert Thorn in the film is Jeremy Thorn in the book), Damien is described as the third attempt to incarnate the Antichrist rather than the first, and the ending is arguably more disturbing on the page because Seltzer plays with ambiguity until the final sentence.
This is one of the ten movies you didn’t know became books that can genuinely be called a commercial publishing phenomenon, not just a film tie-in.
4. Back to the Future (1985)
The book: Back to the Future (1985) by George Gipe
George Gipe wrote the Back to the Future novelization from an early draft of the script — before Michael J. Fox replaced Eric Stoltz in the lead role, and before the screenplay reached its final form.
This created a book that diverges from the finished film in ways that now function as a kind of alternate-history document of the film’s production. Marty McFly has a different personality.
Doc Brown’s motivation for building the time machine is changed. There are additional scenes, different characterizations, and a subplot involving Marty’s detention that was cut from the movie but dramatized in full in the novel.
The novelization, published by Berkley in July 1985 to coincide with the film’s release, is now a fascinating artifact for anyone interested in how the film evolved. Gipe died the following year after being stung by a bee — a sad postscript to what was one of his final projects.
3. Star Wars: Episode IV — A New Hope (1977)
The book: Star Wars: From the Adventures of Luke Skywalker (1976) by Alan Dean Foster (credited to George Lucas)
This entry deserves special attention because it is not technically a movie that became a book. It is a book that came out before the movie — six months before, in November 1976, with Ballantine Books releasing it under George Lucas’s name.
Lucas’s name is on the cover, but the book was ghostwritten by Alan Dean Foster, who was paid to expand the screenplay into prose and also commissioned to write a potential low-budget sequel novel in case the film flopped. The novelization sold out its initial print run of 500,000 copies by February 1977.
Within three months after the film’s release, Ballantine had sold 3.5 million copies. Lucas later acknowledged the arrangement openly and credited Foster in later editions.
What makes this one of the ten movies you didn’t know became books that genuinely changes the story is the prologue: the novelization contains a political description of Emperor Palpatine’s rise to power that predates and in some ways contradicts the prequel trilogy Lucasfilm later made. It also contains scenes cut from the final film, and spells “Wookiee” as “Wookie.”
These details, small and large, make the book a living record of Star Wars before Star Wars existed in its canonical form.
2. Star Trek II: The Wrath of Khan (1982)
The book: Star Trek: The Wrath of Khan (1982) by Vonda N. McIntyre
Vonda N. McIntyre won the Hugo Award and the Nebula Award, both for Dreamsnake, before she wrote this novelization. She was not a hired hand.
She was a recognized literary voice in science fiction who happened to write media tie-ins, and it shows. McIntyre’s novelization of The Wrath of Khan is widely considered among Star Trek fans to be the gold standard of the form: it restores the theatrical cut of the film to a longer version closer to the script, establishes that Saavik is half-Romulan (a detail the film omitted), and reveals that the young engineer Peter Preston killed in the film is Scotty’s nephew — something cut before release that radically changes the emotional weight of that scene.
McIntyre also created the given name “Hikaru” for Sulu, which later became canon when it was inserted into the script of Star Trek VI: The Undiscovered Country by director Nicholas Meyer. In other words: a novelization contributed a character name to official Star Trek mythology. That’s not something most tie-in novels can claim.
1. 2001: A Space Odyssey (1968)
The book: 2001: A Space Odyssey (1968) by Arthur C. Clarke
The most significant of the ten movies you didn’t know became books is, in a technical sense, not really a novelization at all. Stanley Kubrick and Arthur C. Clarke developed the novel and the screenplay simultaneously, starting from a prose treatment and Clarke’s 1948 short story “The Sentinel.”
They originally planned to write the novel first and the screenplay after. In practice, the two works evolved in parallel, with the film released first and the book published shortly after.
Clarke later described the writing credit situation with characteristic precision: the screenplay, he said, should be credited to “Kubrick and Clarke,” and the novel to “Clarke and Kubrick” — with each man’s name first in the medium where he did the most work. The novel fills in what Kubrick deliberately left enigmatic.
It explains the intentions of the alien intelligence, makes explicit what the monolith does, and takes the mission to Saturn rather than Jupiter (Kubrick changed the destination because the production couldn’t build convincing Saturn’s rings). Clarke’s prose version of the Stargate sequence and the film’s final act gives readers tools for interpreting Kubrick’s deliberately ambiguous images — without, it should be said, fully closing the door on mystery.
By 1992, the novel had sold three million copies worldwide.
It spawned three sequels (2010, 2061, 3001), all by Clarke, and none by Kubrick, who had no involvement in any of them. It remains one of the few cases in cultural history where a film and a novel were genuinely co-created — and where neither work can be fully understood without reference to the other.
What Makes Reverse Adaptations Different
The ten movies you didn’t know became books covered here don’t all work the same way, and that’s part of what makes the category interesting. Some, like The Omen, were marketing tools that outperformed their origins.
Some, like The Abyss and Wrath of Khan, are literary expansions that add genuine depth. Some, like Back to the Future, are now historical documents of films that didn’t yet exist in their final form. And one, 2001, is something rarer: a co-creation where the film version and the prose version are parallel expressions of the same ideas, neither one derivative of the other.
The novelization as a form peaked in the 1970s and 1980s — the era Tarantino described as his reading childhood — and declined with home video, which let audiences revisit films whenever they wanted. But it never disappeared. Del Toro and Funke’s Pan’s Labyrinth novelization arrived in 2019 and became a bestseller.
Tarantino’s debut novel shipped in 2021 and hit number one. The appetite for going deeper into the worlds that cinema builds, through reading, through inner life, through the kind of access to character psychology that prose makes possible — that doesn’t seem to be going anywhere.
