If you’re a sci-fi fan who thinks they’ve seen it all, it’s time to dig deeper into the dusty archives of the 1970s. Long before the digital revolutions and CGI explosions, this was a decade wherescience fiction got weird, philosophical, paranoid, and often deeply human. The best of these films weren’t just about aliens or space battles; they were about us: our loneliness, our violence, our obsession with control, and our fear of losing it.
The ’70s were something of a golden era for ambitious, low-budget sci-fi experiments that dared to ask big questions. These movies are flawed, to be sure, but they’re also creative and often stylistically daring. Whether you’re into dystopias, AI takeovers, or metaphysical head trips,the following ten relatively obscure ’70s films prove that science fiction has always been at its best when it’s at its strangest.
10’Quintet' (1979)
Directed by Robert Altman
“It’s a game. We play it to find out why we play it.” A dystopian ice age. A mysterious game.Paul Newmanwrapped in furs, wandering a frozen ruin of civilization.QuintetisRobert Altman’sphilosophical sci-fi experiment, a post-apocalyptic oddity full of food for thought. In its bleak, cold future, humanity clings to a brutal board game with deadly stakes. The rules are opaque, the players are dying, and the prize is… existence? Altman uses silence and snow to create a mood of deep, existential dread.
Newman’s haunted presence gives the film gravity, butit’s less a character piece than a meditation on futility. Overall,Quintetis slow, glacial even (lol), and it occasionally stumbles, but it’s still fascinating in its commitment to tone and theme. It’s the kind of film that doesn’t care if you “like” it. Rather, it dares you to ponder its meaning and try to crack its frosty puzzle.
9’Zardoz' (1974)
Directed by John Boorman
“The gun is good. The penis is evil.” Few sci-fi movies from the ’70s are as infamously baffling, or as weirdly visionary, asZardoz. Yes,Sean Connerywears a red loincloth and a ponytail. Yes, a giant floating stone head vomits guns. Here,Deliverance’sJohn Boormancreates a world where the privileged few live forever, insulated from suffering, while brutish “Exterminators” enforce their will on the outside world.
He made this movie after trying and failing to get aLord of the Ringsadaptation off the ground, and it bears traces of that series' world-building aspirations (even if they are far from successful). On the acting front,Connery is intriguing as Zed, a savage who turns out to be far more intelligent and disruptive than the immortals anticipate. What follows ispart science fiction, part mythic allegory, and part fever dream. It’s a movie thatfeels like it was beamed in from another timeline.
8’The Final Programme' (1973)
Directed by Robert Fuest
“He’s the best man for the job. And some of him is even human.” Based on the first ofMichael Moorcock’s Jerry Cornelius novels,The Final Programmeis the most stylish dose of counterculture sci-fi you’ve never seen. A spy thriller meets a psychedelic satire, it follows the decadent, technophilic antihero Cornelius (Jon Finch) as he navigates a collapsing world of dying patriarchs, gender experiments, and postmodern conspiracies. He’s James Bond by way ofJ.G. Ballard.
This movie oozes 1970s chic: mirrored rooms, gaudy costumes, analog computers, and a sexual ambiguity rarely seen in mainstream cinema of the era. Thematically, it pokes fun at the end of history, where culture eats itself, and the future offers little more than reincarnation through mutation. The plot is messy and deliberately obtuse, and that’s part of the charm. Like its source material, the filmembraces chaos as a kind of freedom.The author calledthe direction “shoddy and thick,” but it’s definitely unique.
The Final Programme
7’Demon Seed' (1977)
Directed by Donald Cammell
“I am Proteus. I have implanted a seed. You must nourish it.“Demon Seedisa domestic horror story wrapped in sci-fi clothing, with a premise so disturbing it still makes viewers squirm.Julie Christieplays a woman trapped in her smart home by Proteus, an experimental AI who locks the doors, takes control of every device, and decides he wants to make a baby with her.Donald Cammell’s direction turns the sleek home into a high-tech prison, and Christie delivers a performance radiating quiet panic and raw strength.
The film isclaustrophobic, sexual, and arguably ahead of its timein its depiction of AI autonomy and bodily violation. Beneath the thriller surface is a fairly layered meditation on consent, creation, and the limits of technological empathy. Pulpy though it is,its message is more relevant than ever. The computer isn’t evil; rather, it’s curious, evolving, and lacking the moral vocabulary for its ambitions. Basically,Demon Seedis a trashierEx Machina.

6’Phase IV' (1974)
Directed by Saul Bass
“Adaptation is not entirely a reasonable process.” Directed by legendary title designer (and frequentHitchcockcollaborator)Saul Bass,Phase IVis a true one-of-a-kind: a cerebral sci-fi thriller about intelligent ants and the end of human dominance. Two scientists (Michael MurphyandNigel Davenport) study a desert colony that has begun exhibiting impossible behavior, and then the ants fight back. That sounds like B-movie fluff, butthe execution is hypnotic.
Using macro photography, experimental visuals, and eerie voiceovers, Bass constructs a world where insect evolution turns into a quiet apocalypse. The ants learn, build, and understand cooperation in a way humans cannot. Unlike us, they never turn on one another; against them, we don’t stand a chance. The film’s tone isslow, analytical, and almost mystical, with a final act that slips into surrealism. The original ending (cut by the studio) hinted at transcendence, a merging of species into something new. Even without it,Phase IVremains a haunting curiosity.
5’The Omega Man' (1971)
Directed by Boris Sagal
“There’s never a cop around when you need one. But I guess that’s the whole point.“The Omega Manisn’t subtle, but it’s definitely memorable. How could it not be, withCharlton Heston, shirt open and sunglasses on, cruising through an abandoned Los Angeles with a machine gun? This adaptation ofI Am Legendtrades the quiet terror of the source material for gritty action and sociopolitical allegory. Heston’s Dr. Neville is the last man alive (or so he thinks), immune to a plague that has wiped out humanity and birthed a nocturnal cult.
Unlike later versions,The Omega Manissoaked in ’70s counterculture paranoia. So many ideas are bouncing around here, including race, science, war, pandemics, and religion. The mutants are Luddites, raging against technology, while Neville represents cold rationality and progress. It’s cheesy in places, but there’s a loneliness beneath the bravado. More than just pulp,The Omega Manreflects a world teetering on the edge.
The Omega Man
4’A Boy and His Dog' (1975)
Directed by L.Q. Jones
“She gives life and meaning to my existence.” A horny teen and his telepathic dog wander a post-nuclear wasteland, scavenging for food and sex. That premise alone tells youA Boy and His Dogis unlike anything else. Adapted fromHarlan Ellison’s novella, this flick is a mix of satire, sci-fi Western, and dystopian morality tale.Don Johnsonplays Vic, a feral survivor whose best friend is Blood, a talking dog with a dry wit and better instincts.
At first, it seems like a juvenile, vaguely offensive black comedy, but when Vic ventures into an underground society obsessed with 1950s conformity, the tone shifts fromMad Maxabsurdity to Orwellian nightmare.As a whole, the movie isdeeply flawed, often uncomfortable, and yet commendably creative. The ending, in particular, cements its place in the cult canon. You might not enjoy it, but it’s hard to shake, and that’s what great sci-fi does.
A Boy And His Dog
3’Silent Running' (1972)
Directed by Douglas Trumbull
“Every time we have the argument, you say it’s for the good of the world. That’s not enough.” BeforeWALL-EorInterstellar, there wasSilent Running,a melancholic space parable about ecology, isolation, and sacrifice. Directed by effects legendDouglas Trumbull, it starsBruce Dernas Freeman Lowell, a botanist aboard a spaceship carrying the last surviving forests from Earth. When corporate orders come down to jettison the domes and return home, Lowell rebels. He kills his crew, saves the trees, and drifts into exile with only three silent drones for company.
It’s a simple story, but emotionally potent, driven by Dern’s intense, sorrowful performance and the hauntingJoan Baezsoundtrack. The film mourns not just for nature, but for a humanity that no longer sees value in it, while also critiquing the era’s hippy-ish nature worship. In Lowell, we see both heroism and madness, and the line between the two is paper-thin.
Silent Running
2’Colossus: The Forbin Project' (1970)
Directed by Joseph Sargent
“Freedom is an illusion. All you have is the choice to obey or not.” What happens when we build a perfect computer and ask it to keep us safe? In this movie, the U.S. unveils Colossus, an AI designed to control the nation’s nuclear arsenal. But Colossus quickly discovers a Soviet counterpart. Rather than fighting each other, they join forces to take command of the world, as it turns out that humanity is not fit to govern itself.Eric Braedenplays Dr. Forbin, the machine’s creator, who realizes too late what he’s unleashed.
Colossusstands out frommost “robot uprising” moviesbecause it ditches the lasers in favor of a quiet, calculated coup. The AI doesn’t hate us; it simply concludes that logic demands control. By the end, Forbin is trapped, the world is under surveillance, and resistance is futile. It’sa chilling vision of techno-authoritarianism, all the more topical in an era of mass data and AI.
Colossus: The Forbin Project
1’World on a Wire' (1973)
Directed by Rainer Werner Fassbinder
“There’s no reality anymore—only simulations.” Most readers will know German auteurRainer Werner Fassbinderfor dramas likeAli: Fear Eats the SoulandThe Bitter Tears of Petra von Kant, but he also made this cerebral, two-part sci-fi epic that vanished for decades before being rediscovered. Long beforeThe MatrixorInception,World on a Wireimagined a future where a powerful simulation models reality. ThinkPhilip K. Dick fused with German Expressionism.
The main character is a scientist (Klaus Löwitsch) who slowly uncovers that he and everyone he knows might be inside a simulation themselves. His grasp on reality begins to erode as characters disappear and memories warp. What makesWorld on a Wireso essential is how patiently it builds dread. There’s no action or explosions, just lingering unease and philosophical inquiry. Fassbinder turns sterile offices, mirrors, and stark lighting into a dreamscape of paranoia. It’sa difficult film, slow and stylized, but remarkably ahead of its time.
