Movies & TV Hard Science Fiction 10 Hard Sci-Fi Movies Not Set in Space When you prefer your sci-fi to be a little more grounded By Matthew Byrd | Published on July 6, 2026 Credit: Columbia Pictures Comment 0 Share New Share Credit: Columbia Pictures Hard sci-fi movies are surprisingly rare beasts. As is the case with hard sci-fi video games, it’s a subgenre that has really exploded in popularity in recent years thanks largely to the release of a few tentpole projects. In the case of movies, The Martian and Interstellar most certainly helped kick off a new era of studios slowly realizing there is a sizeable (if sometimes simply vocal) audience for genre movies that feel a bit more scientific and a little less fantastical. Interestingly, what few hard sci-fi movies we have largely take place in outer space. That’s understandable given that we are still talking about sci-fi movies, but the fact of the matter is that some of the most important and fascinating hard sci-fi films never leave our planet. These are movies that, at the very least, remind us that we have so much to learn about ourselves and our world before we ever start looking toward the stars. And though the classification of some of these movies as hard sci-fi may ruffle a few feathers (don’t such discussions always do so?), these films all show the fantastical possibilities of theories, processes, practices, experiments, and the logical pursuit of the meaning behind advancements and wonders. Above all, these movies are, rather appropriately, quite grounded. Colossus: The Forbin Project (1970) A fundamental problem with hard sci-fi films from an older era is that many of their ideas will have inevitably been disproven in the years that followed. What you’re really looking for when praising such a movie is the validity of its intentions. So far as that goes, Colossus: The Forbin Project stands apart. In the not-too-distant future, the United States has decided to give a computer program known as Colossus control of its entire defense system. Yes, things go wrong, but the brilliance of this movie lies in the way it examines the slow-burn of that process. The irony here is that Colossus’ attempts at authoritarian control in the name of global peace actually force the United States and Russia to engage in talks about deactivating their nuclear weapons. The often surprising events that follow really examine how such programs represent our darkest needs for control despite what we may say they are intended for. It’s all wrapped in surprisingly plausible observations about how such programs (and humanity) may act in this increasingly relevant scenario. The Andromeda Strain (1971) Considered to be one of the premier examples of relative scientific accuracy in a movie, Michael Crichton’s The Andromeda Strain has lost little of its potency in the 55 years since its release. It’s an appropriate legacy for a movie that boasts this banger of a tagline: The picture runs 130 minutes… The story covers 96 of the most critical hours in man’s history… The suspense will last through your lifetime! The Andromeda Strain begins in the aftermath of a catastrophic event that resulted in the death of all but two residents of a small New Mexico town. A group of scientists soon discover that the event was caused by the return of a satellite that has apparently brought back an unknown deadly substance. For a movie that mostly consists of older gentlemen examining ‘70s technology and discussing hypothetical possibilities, The Andromeda Strain is a true thriller. There is so much joy to be found in watching these incredibly capable scientists realistically breaking down a situation that is both fantastical (quite literally alien) and perhaps a little too close for comfort in modern times. Altered States (1980) Altered States is undoubtedly the trippiest and most surreal movie one will ever try to describe as “hard sci-fi.” If you asked me to try to justify the validity of the movie’s many scientific ideas, you’d soon be speaking to a melting mass desperately trying to escape an awkward situation. Instead, the argument for this film’s inclusion is partially based on its appreciation of the wonderful, almost magical possibilities of science itself. Loosely inspired by the experiments of John C. Lilly and contentiously based on a novel by Paddy Chayefsky, Altered States follows a researcher who uses a combination of sensory deprivation and hallucinogens to explore the furthest reaches of the human mind. What follows is pretty much what you’d expect from a Ken Russell movie. In lesser hands, such a story could have been a “hell yeah, brother!” moment for microdosing bros everywhere. Fortunately, Altered States is more interested in the humanity behind our sometimes unfathomable urge to “transcend.” Gattaca (1997) One of the great hard sci-fi films regardless of setting, the acclaim for Gattaca has grown louder in recent years due to both the relevancy of its core scientific subject matter (eugenics) and the subtle, yet undeniable craft of its filmmaking and storytelling. Gattaca follows a young man named Vincent Freeman who, at a young age, was determined to be a genetically inferior human with a short lifespan. Disheartened by this news, Vincent’s parents decide to have a genetically altered second child whom Vincent develops a brotherly rivalry with as he attempts to subvert his supposed genetic fate and join a space program. Gattaca’s greatest claim to fame may be the world it builds around the idea of eugenics becoming common. It’s not that the ethics of an unethical idea are not discussed, but rather that they are discussed within the context of a setting in which Pandora’s Box has already been opened. It is a warning about a pressing issue that doesn’t talk down to viewers so much as it invites you to listen to a challenging but pressing conversation. Primer (2004) Watching Primer is an exercise in overcoming two notable frustrations. The first is the nature of the film’s plot, which attempts to convey a “realistic” form of time travel that results in a story that is often maddeningly difficult to follow without the help of several charts and often unbearable explainers. The second is the nature of the movie’s fanbase, which certainly hosts a number of film, tech, and science bros whose overly vocal fondness for the film generated a polarizing effect. It’s classic Breaking Bad syndrome stuff. Now that we’re somewhat removed from the peak of Primer fandom, though, it’s easier than ever to appreciate that the film is very much what its two main characters are conducting: a messy experiment. The beauty of Primer’s premise is that it’s not really a movie about time travel. It’s a movie about two tech bros (admittedly tech bros who are intelligent in a very specific way) whose genuine desire to create something beneficial leads them down a rabbit hole forged by their own hubris. It’s the story of the fate that befalls many modern tech “visionaries” and a fairly noble attempt to narratively incorporate some heavy scientific ideas. The Man From Earth (2007) It’s difficult to talk about The Man From Earth as a work of potential science fiction (or even hard sci-fi) without getting too deep into spoilers. Even then, your classification of the material may be based largely on your interpretation of it. Regardless, The Man From Earth is a testament to the beauty of the scientific method and simply “figuring things out.” The film introduces us to a respected professor named John Oldman who is throwing a party for his friends and colleagues before he moves away. At that party, Oldman tells his friends he’s not quite the man they think he is. In fact, he claims to be a kind of eternal being who has been alive for thousands of years. What follows is a prolonged conversation between experts in various fields who all attempt to disprove that seemingly impossible claim. If the thought of such a conversation excites you (and you don’t mind movies shot on what is essentially a negative budget), then you will absolutely love this modern masterpiece about the intersection between hard science and something close to faith. Robot & Frank (2012) Frank Weld is a retired ex-thief who is suffering from dementia. His son can’t quite bring himself to put his father in a home, so he buys Frank an advanced robot that is capable of offering both care and companionship. Bolstered by the robot’s presence, Frank begins to slip into old habits to win the affection of a local librarian in ways that cause his kids to argue over the ethics of their father’s new care system. Robot & Frank is a heartbreaking (seriously, prepare yourself for this one) examination of our cultural treatment of the elderly and how technology can factor into such arrangements for good and ill. It’s the “good” element of the equation that makes this a particularly challenging watch from an ethical scientific standpoint. There is a wholesome genuineness to the relationship between the robot and Frank that is undercut by the horrors of the idea of leaving our loved ones in the hands of technology in the final years of their lives. It is a powerful and realistic examination of the ethics of such advancements and our struggles to live (and die) with it all. Her (2013) It’s not that anyone thought that Her was an unrealistic depiction of fundamentally broken men who turn to chatbot companions in order to falsely fulfill a desire for relationships in their lives. It’s just that you kind of have to wonder why certain prominent people saw this as a weirdly aspirational premise rather than a nightmare dystopian vision of how much humanity we are willing to sacrifice in the name of weaponizing and monetizing loneliness. It does in fact feel a little strange to talk about Her as a work of science fiction given that we’re living in a world where a man like Joaquin Phoenix’s Theodore Twombly has access to these same tools—where real people may not only fall deeply in love with a program but be empowered by the madness of it all. The film’s real-world impact on technology is terrifying, but it is also a testament to the ways this movie conveys a darkly, darkly sweet portrayal of what we will let in our hearts when they have been ripped open wide enough. Coherence (2014) Eight friends attend a dinner party the night that a comet is expected to pass over the Earth. When the nearby comet seemingly knocks out the power in the area, the friends decide to go to the one house in the neighborhood that seemingly hasn’t lost electricity to use their phone. Upon inspection, they discover that the house seems to be kind of twisted mirror version of their own home. It’s a fantastical idea to say the least. The brilliance of Coherence as a piece of hard sci-fi, though, can be attributed to the nature of its characters. They are not scientists. In fact, one of them is desperately trying to reach his physicist brother in order to help figure out what is happening to them. Yet, they try their best to logically solve this incredible situation through a series of tests that are at least based on their understanding of sound scientific principles. If you are like me and are especially fond of a weirdly specific subgenre I will refer to as “logical solutions to supernatural problems,” this is certainly one of the best movies you can immediately add to your watchlist. Ex Machina (2015) An obvious inclusion, perhaps, though some things earn that distinction for a reason. In terms of this weirdly specific subgenre within a subgenre, Ex Machina is both the culmination of several trends we’ve previously discussed and a rather pressing look into the then-future, now-present of the mentalities and personalities we’ve allowed to dictate our technological reality. Nathan Bateman has developed the first humanoid robot with artificial intelligence that is capable of passing a version of the Turing Test. He has also, to put it bluntly, designed an elaborate sex slave. Oscar Isaac gives an arguable career performance (a hell of a statement in its own right) as a tech CEO who almost feels comically on the nose when viewed through the lens of the modern world. His curated overly hyper-masculine aura lends an unearned air of superiority to what is essentially a modern-day Dr. Frankenstein. Actually, this is the far better example of Isaac portraying Dr. Frankenstein. Like movies before it, Ex Machina deals with artificial intelligence, eugenics, and robotics. However, it also asks “Who decided to let these narcissistic dudes dictate the future of humanity?” [end-mark] The post 10 Hard Sci-Fi Movies Not Set in Space appeared first on Reactor.
