One of the biggest films to come out of 2026 so far is the hard science fiction movie Project Hail Mary. Based on Andy Weir’s 2021 novel, it follows Ryan Gosling as a middle school teacher and former molecular biologist, Ryland Grace, who wakes up from an induced coma aboard an interstellar spacecraft with no memory of how he got there. Despite the grim, apocalyptic stakes of a dying sun, the film maintains a level of uplifting whimsy and hope that pays homage to the optimistic era of space epics like E.T. the Extra-Terrestrial, Wall-E, and Star Trek.
Already considered the sci-fi movie of the decade, the film has been lauded for its scientific accuracy, realistic astrophysics, and relatively minor need for suspended disbelief in its speculative concepts. Reminiscent of hard sci-fi cinematic classics of the 20th century, Project Hail Mary is a visually dazzling modern masterpiece that evokes a sense of nostalgia for classic science fiction stories about curiosity and earnest cooperation between Ryland and the extraterrestrial, Rocky. In the face of an extinction-level event, the film serves as an intergalactic buddy comedy about sacrifice, scientific discovery, and interspecies friendship.
Europa Report Depicts Realistic Space Exploration
Criminally underrated, Europa Report is a near-perfect hard sci-fi film that very few remember despite its harrowing found footage premise. Blending a classic horror trope with a heavy science fiction formula, the film recounts the fictional story of the first crewed mission to Jupiter’s icy moon in the hope of finding evidence of extraterrestrial lifeforms who persist in their long-haul space missions despite a series of crises that begin with a technical failure that causes the loss of all communications with Earth.
Inspired by real footage from the International Space Station and space walks from 1981 to 2011, the NASA Space Shuttle. Incredibly detailed, the film’s depiction of Europa was based on real-world data from NASA and the Jet Propulsion Laboratory’s maps of the moon’s surface to ensure scientific accuracy. Despite the competency of its characters, Europa Report’s first contact scenario is not ideal, but with a dedication to hard sci-fi elements, it is the perfect film for lovers of Project Hail Mary.
Coherence Is an Underrated Low-Budget Sci-Fi Thriller
A rarely-discussed sci-fi masterpiece, 2013’s Coherence is a claustrophobic psychological thriller about quantum mechanics. Directed by James Ward Byrkit in his cinematic debut, the film centers on eight friends at a dinner party whose lives are upended when a passing comet distorts reality and turns the neighborhood into a “quantum roulette wheel” where characters unknowingly cross into alternate branching realities filled with doppelgängers.
Like Project Hail Mary, this low-budget indie film explores an intellectually engaging science fiction plot. Both movies are stellar examples of “competence porn” with their intelligent characters logically reasoning their way out of impossible situations. Rather than focusing on action or violence, the tension comes from the characters testing, failing, and adapting their theories to solve their respective scientific mysteries. Sharing core themes of overcoming isolation, puzzle-solving through rigorous scientific methods, and relying on mathematics as a universal constant, Coherence is the perfect hard sci-fi follow-up to Project Hail Mary.
Directed by Robert Zemeckis, the 1997 film Contact follows Jodie Foster as Dr. Ellie Arroway, a SETI (Search for Extra-Terrestrial Intelligence) scientist, who discovers an alien radio signal from the Vega system. Based on planetary scientist Carl Sagan’s hard sci-fi novel, it has been widely applauded for its blend of scientific accuracy, thought-provoking narrative, and familiar optimistic outlook of humanity’s first contact with advanced extraterrestrial intelligence. With an emphasis on radio astronomy and astrophysics, its depiction of modern SETI research is “more accurate… than any Hollywood film in history.”
Praised as a cerebral sci-fi classic, Contact shares a similar premise with Project Hail Mary in which the protagonist takes a solitary leap to solve universal problems. Driven by curiosity and wonder, both films bridge the divide between humans and extra-terrestrials with science as a universal language that serves as a foundational tool for establishing mutual respect, trust, and understanding. Defying sci-fi cinema expectations, Contact delves into science, faith, and humanity’s search for meaning with a positive and inquisitive outlook.
Moon Uses Scientifically Plausible Futuristic Technology
One of the best hard sci-fi films of the 21st century, Moon, starring Sam Rockwell, follows astronaut Sam Bell as he nears the end of a grueling, solitary three-year contract mining Helium-3 on the far side of the moon and discovers a dark, existential conspiracy just days before he is due to return home. Praised for its grounded approach and philosophical depth, the film cements its hard sci-fi premise by exploring the consequences of corporate greed, labor exploitation, identity, and isolation — with the psychological toll of a long-term deep-space mission enhanced by the film’s accuracy regarding harsh lunar environments, logistics of remote space industrialization, and communication delays.
The film’s core concept of mining the lunar surface for Helium-3 to solve Earth’s energy crisis is based on real-life scientific research about the moon’s abundance of the rare isotope of helium, which holds massive potential as a clean fuel for nuclear fusion reactors. Avoiding classic sci-fi tropes, the station’s AI computer becomes a nuanced and helpful ally in a similar manner to the unexpected friendship in Project Hail Mary. The movies also share a similar concept of a lone, highly competent protagonist waking up in deep space as they slowly realize the scope of their mission and its downplayed dangers.
Primer Prioritizes Scientific Accuracy & Technical Jargon
Following two engineers, Aaron and Abe, who accidentally invent a time machine, the 2004 indie film Primer is one of the smartest time travel movies ever made. Exploring the subsequent consequences of time travel — losing control of timelines, multiple duplicates, deception, and a fractured friendship — the film has been praised for its experimental plot, heavy philosophical implications, and complex technical dialogue. Choosing not to simplify complex topics like quantum physics, the film uses real-life jargon and accurate depictions of scientists at work that, while putting more effort on the part of the viewer, make it a dense but hard-earned cerebral watch.
With a realistic science focus, both films use grounded scientific principles as foundations for their respective stories. While Primer focuses on the rigorous theoretical physics and mathematical understanding of time travel, Project Hail Mary examines relativity, xenobiology, and chemical engineering. With both sets of protagonists operating as hyper-intelligent troubleshooters, Ryland Grace solves physical and biological puzzles while Aaron and Abe systematically solve the physical, logistical, mathematical, and mechanical failures of their time travel experiments. Though Project Hail Mary is a massive, high-budget blockbuster set in interstellar space, Primer is an intimate indie thriller set in a suburban garage with a micro-budget of just $7,000 that presents time travel as a grounded, mundane but terrifyingly complex technological reality.
Arrival Focuses on Xenolinguistics & Alien Communication
Adapting Ted Chiang’s 1998 novella “Story of Your Life”, Denis Villeneuve’s film follows the arrival of twelve mysterious alien crafts that land worldwide and the US army’s recruitment of linguist, Dr. Louise Banks (portrayed by Amy Adams), who must communicate with the extraterrestrials. The 2016 film focuses on translating the aliens’ language while also trying to decipher their intentions. In understanding their complex language, the protagonist’s linear perception of time is altered, allowing Louise to experience memories of future events and prevent global war. While it takes the Sapir-Whorf Hypothesis — language influences perception — to implausible levels, Arrival is lauded for depicting the interactive nature and theorization of linguistics in a hard sci-fi but entirely plausible setting.
Perfectly paired with Project Hail Mary, both movies intersect with themes of first contact and the difficulties of interspecies language barriers. Exploring alien diplomacy, they both highlight the universal language of science as a salvation against extinction-level events and the importance of collaboration. Both narratives also follow highly specialized experts who are abruptly recruited by governments and global authorities to decipher interstellar mysteries. Pivoting away from the overused alien invasion tropes, Arrival and Project Hail Mary transform into intimate, emotionally driven stories about curiosity, trust, and forming deep friendships.
Interstellar Is Grounded in Realistic Theoretical Physics
The widely celebrated sci-fi epic, Interstellar, focuses on a dystopian future where Earth is being rendered uninhabitable by catastrophic blights, famine, and dust storms. Starring Matthew McConaughey, Anne Hathaway, Jessica Chastain, and Michael Caine, the 2014 film follows a crew of astronauts, led by ex-pilot Cooper, who travel through a newly discovered wormhole near Saturn in the hopes of finding a new, habitable planet to secure the survival of the human race. With director Christopher Nolan insisting on scientific accuracy, Interstellar received universal praise for grounding its speculative cosmic concepts in actual theoretical astrophysics.
With Project Hail Mary and Interstellar’s similarly heavy concepts centering on extinction-level threats to Earth where the only hope for survival requires a perilous deep-space mission, both films seamlessly integrate plausible scientific principles — such as relativity, orbital mechanics, mass and energy equations — into their plot points. With similarities running deep across multiple plot and thematic elements, both films feature reluctant astronauts who must sacrifice their normal lives for a seemingly impossible mission and a potential one-way journey. While grappling with the heavy emotional weight of abandoning their familiar worlds, the film shifts to focus on the beauty of space exploration and unexpected companionship — between Ryland Grace’s profound friendship with Rocky and Cooper’s bond with the AI unit TARS.
Apollo 13 Dramatizes a Real-Life Aborted Lunar Mission
One of the best space movies ever created, the 1995 film Apollo 13, dramatizes the harrowingly true story of the 1970 NASA lunar mission. This docudrama stars Tom Hanks, Kevin Bacon, Bill Paxton, and Gary Sinise as the Apollo 13 crew and tells the story of astronauts Jim Lovell, Fred Haise, and Jack Swigert on the ill-fated mission that was intended to be the third moon landing. After an oxygen tank explosion deprives the spacecraft of its much-needed oxygen supply and electrical power, the NASA flight controllers must abandon their mission and fight for survival as Mission Control races to bring them home safely.
Praised as a “gold standard” space drama by former NASA astronauts, director Ron Howard went to great lengths to create a technically accurate depiction of the events, even getting NASA’s assistance in astronaut and flight-controller training for the cast and obtaining permission to film scenes aboard a reduced-gravity aircraft for realistic shots of the weightlessness experienced by astronauts in space. Similarly, Apollo 13 and Project Hail Mary both center on isolated astronauts relying on their scientific ingenuity, precise calculations, and improvised engineering to survive a failing spacecraft with stories rooted in hard science fiction and real-life events. Using science as a character, the films build narrative tension by solving a succession of technical chain-reaction crises where one small success simply leads to the next immediate hurdle. Focusing on high-stakes, both crews find themselves cut off from humanity in a claustrophobic space where any mistakes could spell disaster.
The Martian Is Based On Andy Weir’s Debut Novel
Also based on a bestselling hard sci-fi novel by Andy Weir, The Martian, starring Matt Damon, is heavily grounded in scientific accuracy and stands its ground against its cinematic successor. Directed by Ridley Scott, the film follows astronaut Mark Watney, who is stranded on Mars after being presumed dead by his crew when a severe dust storm forces an emergency evacuation. Relying on his botany expertise and engineering skills, he must improvise to survive and “science the shit” out of every arising problem until he can be rescued by NASA.
Similarly grounded with the protagonist’s sarcastic, highly irreverent wit, both movies incorporate Andy Weir’s classic use of levity as a crucial psychological coping mechanism against their extreme isolation, imminent danger, and the harsh, unforgiving realities of being stranded in deep space. With a background in computer science and a lifelong passion as a space enthusiast, the films use Andy Weir’s well-researched science as a foundation for the plots. Highlighting human ingenuity and resilience through sci-fi survival stories that balance intensely high-stakes and lightheartedness, both feature an isolated, highly capable protagonist who must use pure scientific problem-solving, mathematics, and extreme determination to overcome their near-impossible odds.
2001: A Space Odyssey Is the Pinnacle of Hard Sci-Fi Films
Directed by Stanley Kubrick, 2001: A Space Odyssey is a sci-fi epic that follows humanity’s evolution from primitive apes to space-faring intellectuals. A timeless masterpiece, the film focuses on a voyage of astronauts, scientists, and the sentient supercomputer HAL 9000 to investigate an alien monolith that has chronicled the dawn of tools, to an artificial intelligence rebellion in deep space, to a surreal, transcendent rebirth in one of the greatest final shots in cinematic history.
Considered the defining example of hard sci-fi, the film is co-written by Kubrick and renowned sci-fi novelist Arthur C. Clarke, who meticulously roots its space exploration, physics, and technology in known scientific realities. Similar to Kubrick’s 1968 landmark hard science fiction epic, Project Hail Mary contains direct visual and narrative homages to 2001, including helmet lighting design and the acknowledgment of space’s eerie silence.
At their cores, both stories center on a sole astronaut protagonist isolated aboard a specialized, scientific-exploration spacecraft who manages the technical upkeep of the ship as they battle isolation in disorientating circumstances. Prioritizing plausible science over magical technology and moving past initial mistrust of extraterrestrials, both 2001: A Space Odyssey and Project Hail Mary feature profound encounters with non-human intelligences — the mysterious monolith creators and the genius alien, Rocky.
