18 Sci-Fi Concepts Borrowed from Obscure Books and Made Iconic

Many popular sci-fi movies are actually based on older stories that most people have never heard of. These films often took ideas from short stories or less famous novels and turned them into well-known parts of our culture. In many cases, the movie version became more famous than the original book. Here are 18 science fiction ideas that first appeared in lesser-known books.

‘Blade Runner’ (1982)

Ridley Scott’s film, based on Philip K. Dick’s novel, is a classic of the cyberpunk genre. It follows Rick Deckard, who tracks down bioengineered humans called replicants in a futuristic, rain-soaked Los Angeles. The movie thoughtfully examines what it means to be human, and its striking visuals and deep questions continue to inspire filmmakers today.

‘Total Recall’ (1990)

Paul Verhoeven directed a thrilling action movie based on a story by Philip K. Dick, featuring Arnold Schwarzenegger.

‘The Thing’ (1982)

John Carpenter’s film is based on John W. Campbell Jr.’s story, Who Goes There?

‘Edge of Tomorrow’ (2014)

This action movie is based on the Japanese novel All You Need Is Kill. Tom Cruise stars as a soldier caught in a time loop, constantly reliving the same fight against aliens. Each time he’s killed, he restarts, and must use what he learns to finally win the battle with a skilled female warrior. The film brought the idea of ‘respawning’ – common in video games – to the big screen.

‘Arrival’ (2016)

Denis Villeneuve’s film is a thought-provoking science fiction drama based on Ted Chiang’s short story, Story of Your Life. It follows a linguist who tries to communicate with aliens who arrive on Earth in twelve strange spacecraft. As she learns their language, her understanding of time and memory begins to change.

‘Soylent Green’ (1973)

This well-known dystopian story is based on Harry Harrison’s novel Make Room! Make Room!. It portrays a future world struggling with overpopulation, climate change, and dwindling resources.

The story is particularly remembered for its surprising and unsettling reveal about the source of the food everyone consumes.

‘Planet of the Apes’ (1968)

This popular film series began with a novel by French author Pierre Boulle. The story follows astronauts who crash-land on a planet ruled by intelligent, talking apes, where humans are treated as speechless savages. While the movie updates the technology from the book, it keeps the original’s sharp critique of society. The film is famous for its unforgettable final scene, which remains iconic in movie history.

‘Minority Report’ (2002)

As a movie buff, I’m always amazed by how Steven Spielberg takes a cool idea and runs with it. He turned a Philip K. Dick story into this really slick, futuristic thriller called ‘Minority Report.’ The premise is wild – the police can arrest people before they even commit a crime, thanks to these psychics. Tom Cruise plays a cop who gets framed for a future murder and has to go on the run to clear his name. What really blew me away, though, was how the movie predicted things like controlling computers with gestures and those personalized ads that seem to follow you everywhere. It felt so ahead of its time!

‘Paprika’ (2006)

This anime, directed by Satoshi Kon and based on a novel by Yasutaka Tsutsui, centers around a technology that lets therapists enter patients’ dreams. A detective and a dangerous criminal battle it out in a visually stunning and surreal dream world where what’s real and what’s imagined become blurred. The film’s innovative visuals heavily influenced later big-budget movies exploring similar themes, and it’s celebrated as a groundbreaking achievement in animation due to its seamless transitions and intricate story.

‘The Day the Earth Stood Still’ (1951)

The movie originates from Harry Bates’ story, Farewell to the Master, and tells the tale of an alien named Klaatu who comes to Earth with his robot, Gort. Klaatu carries a serious message: humanity must end its violent behavior or risk complete annihilation. A classic film from the atomic age, it strongly promotes the idea of world peace.

‘Invasion of the Body Snatchers’ (1956)

Jack Finney’s novel, The Body Snatchers, first introduced the frightening idea of alien duplicates who have no feelings. The story centers on a town doctor who realizes his neighbors are being replaced by perfect copies grown from large pods. The film adaptation is often seen as a powerful metaphor for the fear of losing one’s individuality during the Cold War, and its conclusion is still considered one of the scariest scenes ever filmed.

‘The Fly’ (1986)

David Cronenberg adapted a short story into a heartbreaking film about the dangers of unchecked scientific ambition.

This intricate film is based on Robert A. Heinlein’s short story, All You Zombies. It follows a time-traveling agent on a last mission to capture a dangerous criminal called the Fizzle Bomber.
