Hollywood loves an original idea almost as much as it loves an original idea that has already survived a test screening somewhere else. Throughout film history, major movies and television shows have borrowed structures, images, characters, or entire premises from works that were less familiar to American audiences.
That does not automatically mean plagiarism occurred. Some examples below are licensed remakes. Others involve openly acknowledged cinematic inspiration, legal settlements, disputed similarities, or coincidences that became irresistible internet debates. Therefore, “imitated” is being used broadly rather than as a legal verdict.
With the courtroom disclaimer safely installed, like a seat belt in a Michael Bay chase scene, here are 17 famous movies and shows with surprising connections to lesser-known films, anime, plays, television episodes, and story treatments.
Famous Movies Inspired by Earlier International Films
1. The Magnificent Seven and Seven Samurai
John Sturges’ 1960 Western The Magnificent Seven is an authorized American remake of Akira Kurosawa’s 1954 Japanese epic Seven Samurai. Kurosawa’s villagers hire samurai to protect their community from bandits; Sturges replaces the swordsmen with gunslingers and moves the action to Mexico.
The remake introduced the basic story to a much wider Western audience, but the original remains the more complex character study. It also established a durable action-movie formula: assemble a team, give every member a specialty, and hope the audience does not notice how many of them have “heroic sacrifice” written on their foreheads.
2. A Fistful of Dollars and Yojimbo
Sergio Leone’s A Fistful of Dollars transformed Kurosawa’s Yojimbo into a dusty Italian Western. Both stories follow a mysterious stranger who arrives in a town controlled by two rival groups and cleverly plays them against each other.
Unlike The Magnificent Seven, Leone’s film was produced without first securing the necessary adaptation rights. Kurosawa and Toho pursued legal action, resulting in a settlement. The dispute did not prevent the movie from launching Clint Eastwood’s international stardom or helping define the spaghetti Western. It did, however, demonstrate that changing a sword into a revolver does not make the paperwork disappear.
3. The Departed and Infernal Affairs
Martin Scorsese’s Oscar-winning The Departed is a credited remake of the acclaimed 2002 Hong Kong thriller Infernal Affairs. Each film centers on two infiltrators: a police officer hiding inside a criminal organization and a criminal operative embedded within the police.
Scorsese relocated the story to Boston, expanded its running time, added regional politics, and allowed Jack Nicholson to behave as though every prop department had personally offended him. Although The Departed became the more familiar title in the United States, Infernal Affairs delivers the same double-agent tension with a leaner, more restrained style.
4. The Ring and Ringu
Before an eerie girl crawled through American television sets in The Ring, she terrified Japanese audiences in Hideo Nakata’s Ringu. Gore Verbinski’s 2002 movie is an official remake, retaining the cursed videotape, the investigative journalist, and the supernatural deadline while altering several characters and visual details.
The remake helped trigger a wave of American adaptations of Japanese horror. It also taught an entire generation that unlabeled videotapes should never be watched. Admittedly, streaming services have made that survival strategy much easier.
5. Vanilla Sky and Open Your Eyes
Cameron Crowe’s Vanilla Sky remade Alejandro Amenábar’s Spanish psychological thriller Open Your Eyes. Both follow a wealthy man whose life collapses after a disfiguring accident, sending him into a maze of romance, memory, dreams, and unstable reality.
Penélope Cruz plays the same character in both versions, creating an unusually direct bridge between the source and remake. Crowe added American pop music, New York imagery, and Tom Cruise running through an empty Times Square. The result is glossier, louder, and more emotionally expansive, while the original remains colder and more mysterious.
6. Twelve Monkeys and La Jetée
Terry Gilliam’s 12 Monkeys was inspired by Chris Marker’s 1962 French short film La Jetée. Marker’s experimental work tells a time-travel story almost entirely through still photographs, following a prisoner haunted by a childhood memory witnessed at an airport.
Gilliam turns that compact concept into a feverish feature involving a pandemic, scientists, false memories, and Brad Pitt operating at approximately 900 words per minute. The shared circular structure is unmistakable, but 12 Monkeys expands the premise into a distinctive dystopian world rather than simply reproducing it.
Acknowledged Influences and Frequently Debated Similarities
7. Reservoir Dogs and City on Fire
Quentin Tarantino has acknowledged that Ringo Lam’s 1987 Hong Kong crime film City on Fire influenced Reservoir Dogs. Both involve an undercover police officer inside a group of jewel thieves, a robbery that goes disastrously wrong, and a tense confrontation among wounded criminals who no longer trust one another.
The similarities are clearest near the end, including the famous multi-person standoff. However, Reservoir Dogs adds its own nonlinear structure, lengthy dialogue, dark comedy, and mysteriously missing robbery footage. Tarantino borrowed a framework, then furnished the house with suits, pop songs, and an alarming quantity of fake blood.
8. The Matrix and Ghost in the Shell
Mamoru Oshii’s animated Ghost in the Shell was a significant visual reference for the Wachowskis while developing The Matrix. Producer Joel Silver recalled being shown the anime as an example of what the filmmakers hoped to achieve in live action.
The works share cyberpunk imagery, networked consciousness, philosophical questions about identity, and bodies connected to digital systems through ports. The Matrix also combines these elements with martial arts, religious symbolism, hacker culture, and a simulated world. It is not a secret remake, but its debt to Japanese animation is an essential part of its cinematic family tree.
9. The Lion King and Kimba the White Lion
Comparisons between Disney’s The Lion King and Osamu Tezuka’s Kimba the White Lion have circulated since the Disney film arrived in 1994. Viewers have pointed to the similar-sounding names, African settings, young lion heroes, cliffside imagery, and supporting animals.
Disney has denied basing its movie on Tezuka’s work, and the plots differ substantially. Kimba concerns coexistence between animals and humans, while The Lion King draws openly from family drama, biblical stories, and Shakespearean tragedy. The controversy remains a case study in how visual parallels can create lasting suspicion without producing a definitive legal finding.
10. The Hunger Games and Battle Royale
The central resemblance is difficult to miss: both stories place young people in a government-controlled competition where they must kill one another. Consequently, Koushun Takami’s novel Battle Royale and its 2000 film adaptation are routinely compared with Suzanne Collins’ The Hunger Games.
Collins has said she was unfamiliar with Battle Royale when developing her series. She has identified reality television, war coverage, Roman history, and just-war theory as major inspirations. Beyond their deadly contests, the stories also pursue different goals. Battle Royale is a savage tale of generational panic, whereas The Hunger Games focuses on propaganda, class inequality, celebrity, and organized rebellion.
11. Black Swan and Perfect Blue
Darren Aronofsky’s Black Swan is frequently paired with Satoshi Kon’s animated psychological thriller Perfect Blue. Both center on female performers whose identities fracture under professional pressure, sexualization, rivalry, and hallucinations. Mirrors, doubles, imagined attacks, and unstable perceptions dominate both films.
Aronofsky had previously recreated a recognizable bathtub shot from Perfect Blue in Requiem for a Dream, openly describing that moment as an homage. He did not identify Black Swan as an adaptation, and ballet melodramas supplied additional influences. Even so, watching the two together produces enough visual and thematic echoes to keep film students supplied with essays until the sun burns out.
12. Inception and Paprika
Satoshi Kon appears again in discussions surrounding Christopher Nolan’s Inception. Kon’s 2006 anime Paprika involves experimental technology that allows people to enter dreams, where private fears and collective fantasies begin invading reality.
Both movies contain dream-sharing devices, collapsing environments, shifting corridors, and characters moving through increasingly unstable mental spaces. Their narratives and tones are nevertheless quite different. Paprika is surreal, playful, and deliberately chaotic; Inception treats dreams like a corporate heist governed by diagrams, synchronized watches, and enough exposition to qualify as an employee orientation program.
Cases That Reached Lawyers, Courts, or Formal Disputes
13. The Island and Parts: The Clonus Horror
Michael Bay’s The Island follows clones raised inside an isolated facility and deceived about their purpose. They eventually learn that they exist to provide organs and biological material for wealthy people outside. That premise strongly resembles the 1979 independent film Parts: The Clonus Horror.
The creators of Clonus sued DreamWorks, identifying numerous similarities in plot, setting, character roles, and sequences. A judge allowed the case to move toward trial, after which the parties reached a confidential settlement reportedly valued in the seven-figure range. This is one of the list’s clearest examples of a little-known movie confronting a much larger production.
14. The Terminator and The Outer Limits
Science-fiction writer Harlan Ellison argued that The Terminator drew from concepts in episodes he wrote for The Outer Limits, particularly “Soldier,” which involves warriors from the future traveling into the present. Commentators have also connected the movie with Ellison’s “Demon with a Glass Hand.”
The matter ended in a settlement, and later releases of The Terminator included an acknowledgment of Ellison’s works. James Cameron strongly rejected the allegation and opposed the settlement. The dispute shows how a shared science-fiction setup can become legally complicated once time travel, killer machines, and studio risk management enter the same timeline.
15. Coming to America and King for a Day
Columnist Art Buchwald submitted a treatment called King for a Day about an African ruler who visits the United States and experiences an unexpected change in status. After Paramount released Coming to America, Buchwald argued that the studio had used his concept without providing the compensation required by their agreement.
A court concluded that the Eddie Murphy comedy was based on Buchwald’s treatment, making this more than a casual fan comparison. The case also became famous for exposing Hollywood’s unusual profit-accounting methods. Apparently, even a blockbuster can be declared financially unsuccessful when a sufficiently creative calculator is invited to the meeting.
16. The Shape of Water and Let Me Hear You Whisper
Paul Zindel’s estate alleged that Guillermo del Toro’s The Shape of Water resembled Zindel’s play Let Me Hear You Whisper. Both involve a cleaning woman working at a research facility who develops compassion for a captive aquatic creature and attempts to help it escape.
The legal outcome is crucial. The lawsuit was dismissed, and the claim was later withdrawn. Zindel’s son publicly acknowledged that information uncovered during litigation showed the plagiarism allegations were unfounded and recognized del Toro as the movie’s creator. The shared premise made headlines, but the final record supports independent creation rather than imitation.
17. Stranger Things and Montauk
Filmmaker Charlie Kessler claimed that the Duffer brothers used ideas from his short film Montauk when creating Stranger Things. The projects shared connections to secret experiments, supernatural events, missing people, and the Montauk area. The Netflix series was even developed under the working title Montauk.
However, Kessler withdrew his lawsuit before trial. He stated that documents from 2010 and 2013 demonstrated that the Duffers had independently developed their project before his alleged pitch. The final outcome therefore does not support the claim that Stranger Things copied his film, even though the dispute remains a useful example of how similar concepts can produce dramatic accusations.
The Experience of Discovering the Lesser-Known Work
Discovering that a favorite blockbuster has an older cinematic relative can feel strangely personal. The first reaction is often suspicion: “Have I been enjoying the expensive photocopy?” Then curiosity takes over, and the earlier work becomes impossible to ignore.
Watching Infernal Affairs after The Departed, for example, does not make Scorsese’s movie evaporate. Instead, it reveals how two filmmaking cultures handle the same dramatic machinery. The Hong Kong film is compact and controlled. Its American remake stretches the premise into a sprawling story about identity, institutions, masculinity, and Boston accents capable of damaging nearby furniture.
The experience becomes even more interesting when the relationship is based on influence rather than an official remake. Seeing Ghost in the Shell after years of knowing The Matrix can create a rapid series of recognitions. A cable enters a body. Green digital information fills the screen. A character wonders whether consciousness can be trusted. Familiar images suddenly acquire a history.
Anime comparisons are particularly revealing because American entertainment once treated Japanese animation as a niche product. Films such as Perfect Blue and Paprika reached smaller U.S. audiences than the live-action works later compared with them. Today, streaming and restored releases make it easier to examine those connections. Viewers can finally see that cinematic innovation does not always travel from the largest studio outward. Sometimes it starts with an animated feature that played in a few theaters and gradually reshapes mainstream visual language.
Legal disputes produce a different viewing experience. After learning about Parts: The Clonus Horror, it becomes difficult to watch The Island without mentally comparing facilities, clone societies, escape sequences, and organ-harvesting revelations. The later film may have more explosions, but explosions are not an intellectual-property cleansing ritual.
Other comparisons become weaker under close examination. Reading about the Stranger Things dispute may initially make the similarities with Montauk sound suspicious. Learning that earlier documents supported independent creation changes the picture. Likewise, the case involving The Shape of Water demonstrates why initial accusations should not be repeated as settled truth after evidence has undermined them.
The most rewarding approach is neither automatic outrage nor automatic dismissal. Watch both works. Compare their structures, themes, images, and historical contexts. Check whether an adaptation was licensed, an influence was acknowledged, a lawsuit was settled, or a claim was rejected. “These stories resemble each other” is an invitation to investigate, not proof that someone sprinted out of a midnight screening carrying a stolen screenplay under a trench coat.
Ultimately, finding the lesser-known work often increases appreciation for both productions. The earlier film gains overdue attention, while the famous one can be evaluated more honestly. Cinema is a long conversation among artists, industries, countries, and generations. Sometimes the conversation is respectful. Sometimes it requires lawyers. Either way, the credits rarely tell the entire story.
Conclusion
Movies inspired by other movies are not unusual. Storytelling has always involved adaptation, reinterpretation, homage, genre conventions, and creative borrowing. What matters is the nature of the connection.
The Departed and The Ring are recognized remakes. The Matrix openly carries the visual influence of Ghost in the Shell. The Island became involved in a substantial legal settlement, while allegations involving Stranger Things and The Shape of Water were withdrawn or acknowledged as unsupported.
The lesson is not that every popular movie secretly stole from an obscure masterpiece. It is that film history becomes more interesting when audiences look beyond the most famous title. Behind many blockbusters stands an international film, experimental short, forgotten television episode, anime feature, stage play, or unproduced treatment waiting to receive its share of the spotlight.
