10 Top science fiction films featuring Clones and Cloning

11 October 2025

The concept of cloning humans has consistently proven to be a captivating plot device in science fiction. It taps into our deepest inquiries about what it means to be human, whether it's questioning the soul of a replicant in Blade Runner or exploring the harrowing ethics of a society that farms humans for organs in Never Let Me Go.

Filmmakers use this narrative element to delve into a myriad of complex themes, pushing the boundaries of our understanding of identity and the consequences of tampering with life itself. By confronting characters with their own duplicates, films like the psychologically haunting Moon and the action-packed thriller The Island challenge our very perceptions of selfhood.

Even blockbuster sagas like Star Wars: Episode II - Attack of the Clones use the concept as a catalyst for galactic conflict, raising questions of individuality on a massive scale. By pitting clones against their originals or revealing a character's entire existence to be an artificial construct, these films provoke audiences to contemplate what truly defines us as unique beings and explore the dangerous consequences of playing god.

Top Ten Films with Great Plots About Clones

1. "Blade Runner" (1982)

Director: Ridley Scott

Script Writers: Hampton Fancher, David Peoples

Lead Actors: Harrison Ford, Rutger Hauer, Sean Young

While not clones in the traditional sense, the "replicants" of Blade Runner are bioengineered beings, physically identical to humans but with a four-year lifespan. 


The film follows detective Rick Deckard, tasked with hunting down and "retiring" a group of rogue replicants. The central conflict lies in the Voight-Kampff test, a device used to distinguish replicants by measuring empathetic response - a flawed system that implies humanity can be quantified.


The film masterfully inverts expectations, as the replicants, particularly Roy Batty, display a profound and poetic desire for life, memory, and meaning, often appearing more human than the burnt-out people hunting them. 


This exploration of artificial memory and manufactured identity forces audiences to question the very definition of humanity and leaves them pondering the film's most enduring mystery: 


is Deckard himself a replicant?

2. "The Island" (2005)

Director: Michael Bay

Script Writers: Caspian Tredwell-Owen, Alex Kurtzman, Roberto Orci

Lead Actors: Ewan McGregor, Scarlett Johansson

In a seemingly utopian, sterile facility, Lincoln Six Echo and Jordan Two Delta live a controlled existence, told that the outside world is contaminated. Their only hope is to win "The Lottery" and be sent to "The Island," the last pathogen-free paradise. 


They soon discover the horrifying truth: they are "agnates," high-priced clones created as living organ insurance for wealthy sponsors. The Lottery is simply a call for a harvest.


Upon escaping into the real world, their journey becomes a high-octane thriller wrapped around a profound ethical dilemma. The film critiques a society where life can be commodified and consciousness is ignored for convenience.


As Lincoln and Jordan develop unique identities beyond their programming, they fight not just for their own survival but for the personhood of all clones, forcing the audience to confront the question of when a copy earns the right to be an original.

3. "Moon" (2009)

Director: Duncan Jones

Script Writers: Duncan Jones, Nathan Parker

Lead Actor: Sam Rockwell

Sam Bell is the sole employee at a lunar mining base, nearing the end of his three-year contract. 


His only companion is an AI named GERTY. Suffering from loneliness and deteriorating health, his world is shattered when he discovers he is not alone - he finds a younger, healthier version of himself. 


He learns that he is one in a long line of clones, each activated with the original Sam's memories and given a three-year lifespan to run the base before being incinerated.


Moon is a masterclass in psychological sci-fi, using its minimalist setting to explore corporate dehumanization where human life is a disposable asset. The film's emotional core is the interaction between the two clones; they start with suspicion and evolve to a state of empathy and self-sacrifice. 


It's a poignant examination of identity, memory, and what it means to be an individual when your entire life and personality have been copied and pasted.

4. "Never Let Me Go" (2010)

Director: Mark Romanek

Script Writer: Alex Garland

Lead Actors: Carey Mulligan, Andrew Garfield, Keira Knightley

Based on Kazuo Ishiguro's haunting novel, this film presents a quiet, alternate version of England where clones are created to provide vital organs for "normal" people. The story follows Kathy, Tommy, and Ruth, who grow up at a seemingly idyllic boarding school called Hailsham. 


They are taught art and literature but are subtly conditioned to accept their fate: a short life ending in a series of "donations" until they "complete."


Unlike other films on this list, there is no rebellion or escape. Instead, Never Let Me Go is a profound and melancholic meditation on mortality and humanity. The characters cling to love, friendship, and art, hoping to prove they have souls worthy of a deferral from their duty. 


The film's tragedy lies in their quiet acceptance of a horrifying system, forcing viewers to question what gives a life meaning if its end is already written.

5. "The 6th Day" (2000)

Director: Roger Spottiswoode

Script Writers: Cormac Wibberley, Marianne Wibberley

Lead Actor: Arnold Schwarzenegger

In a future where cloning pets is common but cloning humans is forbidden by "Sixth Day" laws, helicopter pilot Adam Gibson comes home to find a perfect clone of himself living with his family. 


He discovers he was illegally cloned by a powerful corporation after a supposed accident, and now the company wants to eliminate the original Adam to cover up their crime. Adam must fight to reclaim his life from his duplicate, who is indistinguishable from him in every way, possessing all his memories and feelings.


While an action-heavy film, The 6th Day explores themes of identity and what makes a person unique. The technology of "syncording" allows for a perfect mental and physical copy, raising the question: if the clone believes he is the original, what right does anyone have to say he isn't? The film becomes a battle for the concept of the individual against a corporate entity that sees people as reproducible data.

Arnold also blows some stuff up.

6. "The Island of Dr. Moreau" (1996)

Directors: John Frankenheimer, Richard Stanley

Script Writers: Richard Stanley, Ron Hutchinson

Lead Actors: Marlon Brando, Val Kilmer

Based on the classic H.G. Wells novel, this film follows a UN negotiator who becomes stranded on a remote island ruled by the Nobel Prize-winning geneticist Dr. Moreau. Moreau, in his godlike hubris, has been splicing human DNA into animals to create a new, "pure" species free of humanity's flaws. 


He rules over his grotesque "Beast Folk" as their creator and "Father," enforcing a set of laws to suppress their animal instincts.


The film is a chaotic and disturbing look at the consequences of unchecked scientific ambition. It uses genetic manipulation and cloning to explore the thin veneer of civilization over our primal nature. 


As Moreau's creations begin to regress and their animal natures re-emerge, the island descends into violent anarchy, serving as a powerful allegory for the dangers of playing god and the impossibility of perfecting nature through force.

7. "Aeon Flux" (2005)

Director: Karyn Kusama

Script Writers: Phil Hay, Matt Manfredi

Lead Actors: Charlize Theron, Marton Csokas

Charlize Theron as Aeon Flux

In the year 2415, the last remnants of humanity live in Bregna, a walled city-state run by a congress of scientists. 


This seemingly perfect society is a lie. Centuries prior, a plague rendered humanity infertile, and the ruling regime has maintained the population through cloning, recycling the same DNA for generations. Each new birth is simply a clone of a past citizen, and memories of past lives haunt the living.


Aeon Flux, an assassin for an underground rebellion, discovers this truth and learns she is a clone of the wife of the regime's leader. The film explores cloning as a tool for societal stagnation and totalitarian control. By denying natural birth and evolution, the rulers have created a fragile immortality that is now failing.


Aeon's mission shifts from simple assassination to destroying the system of forced reincarnation, arguing that a true future requires the possibility of new life, not just the repetition of the old.

8. "Star Wars: Episode II - Attack of the Clones" (2002)

Director: George Lucas

Script Writers: George Lucas, Jonathan Hales

Lead Actors: Ewan McGregor, Natalie Portman, Hayden Christensen

While part of a grand space opera, this film places cloning at the very center of its galactic conflict. The Jedi discover a massive clone army, secretly commissioned for the Republic a decade earlier. 


These soldiers are all clones of the bounty hunter Jango Fett, genetically engineered for obedience and accelerated aging. 


They are living weapons, created for a singular purpose: to fight and die for a government that doesn't know it ordered them.

The film presents a fascinating dichotomy in cloning. On one hand, you have the mass-produced, seemingly identical soldiers whose individuality is suppressed. On the other, there is Boba Fett, an unaltered clone whom Jango is raising as his son. 


This contrast explores themes of nature vs. nurture and identity. 


The existence of the clone army serves as a chilling precursor to the Empire, demonstrating how easily a society can sacrifice individuality and ethics for the promise of security, creating a force that would ultimately be used to destroy the very Republic, under the command of figures like Obi-Wan Kenobi and Anakin Skywalker, it was meant to protect.

9. "Splice" (2009)

Director: Vincenzo Natali

Script Writers: Vincenzo Natali, Antoinette Terry Bryant, Doug Taylor

Lead Actors: Adrien Brody, Sarah Polley

Genetic engineers Clive and Elsa are corporate stars for creating new hybrid organisms. Against their company's orders, they secretly splice human DNA into their experiments, creating a rapidly developing female creature they name "Dren." 


As Dren grows, she forms a complex, child-like bond with her creators, who begin to view her with a dangerous mix of scientific curiosity and parental affection.


Splice is a chilling body-horror film that explores the dark side of scientific ambition. The relationship between the scientists and their creation becomes a twisted family drama, blurring the lines between parental responsibility and ethical oversight. 


Dren's unpredictable and violent evolution serves as a terrifying metaphor for scientific pursuits that outpace morality, leading to consequences that are both monstrous and tragic. 


It's a modern Frankenstein story that questions the very nature of what we create and what we owe to it.

10. "The Prestige" (2006)

Director: Christopher Nolan

Script Writers: Jonathan Nolan, Christopher Nolan

Lead Actors: Hugh Jackman, Christian Bale

In this intricate thriller, two rival stage magicians, Robert Angier and Alfred Borden, are locked in a bitter and obsessive feud. To beat Borden's seemingly impossible "Transported Man" trick, Angier seeks out the help of scientist Nikola Tesla, who creates a machine for him. 


The machine, however, doesn't teleport him - it creates a perfect clone a short distance away, leaving the original Angier behind.


The film brilliantly uses cloning as the ultimate magical misdirection. To complete his illusion night after night, Angier must step into the machine, not knowing if he will be the man in the balcony (the clone) or the man who drowns in a tank below the stage (the original).


This horrifying sacrifice highlights the film's core themes of obsession and the self-destructive nature of ambition. 



The clone is not just a copy; it's a testament to how far someone will go to achieve greatness, blurring the line between illusion and reality until the creator himself is lost in the trick.


At its core, the concept of cloning humans in science fiction films taps into our fascination with the unknown and the limitless possibilities of science. It captivates our imagination, encouraging us to question the boundaries of what is possible or morally acceptable.

By exploring the depths of human nature, the essence of identity, and the ethical quandaries that emerge from cloning, these films invite us on a journey of introspection and intellectual exploration, reminding us of the profound impact that scientific advancements can have on our lives and the world we inhabit.

Furthermore, the concept of cloning provides an opportunity for filmmakers to delve into themes of societal control and oppression. 

By creating a world where clones are treated as mere commodities or tools for exploitation, these films shed light on the dehumanization that can arise from treating sentient beings as disposable objects - a la Mickey 17
