Marooned (1969) Columbia Pictures released Marooned in 1969, starring Gregory Peck as NASA Director Charles Keith who leads a rescue mission for stranded astronauts. > Marooned was released before the Apollo 13 incident, which similarly saw American astronauts seemingly stranded in space. ## 14. Primer Shane Carruth's 2004 indie film Primer features an engineer and his colleague developing an amateur time machine in their garage. > Primer is a must-watch for sci-fi movie fans and a tightly constructed one at that. ## 13. Gattaca 1997's Gattaca depicts a dystopian society where genetic engineering leads to discrimination against those with disabilities. > The science behind the story's genetic engineering and eugenics feels particularly well-developed as the cornerstone of this dystopian society. ## 12. The Abyss James Cameron's 1989 underwater thriller The Abyss features American and Soviet teams racing to salvage a sunken submarine from the ocean floor. > Cameron takes care to demonstrate the real-world dangers of deep-sea exploration, including the high pressure and chilling temperatures of the watery depths. ## 11. The Andromeda Strain The 1971 film adaptation of Michael Crichton's novel The Andromeda Strain follows scientists containing a deadly extraterrestrial microorganism. > The movie follows a team of scientists trying to contain the situation before it can wipe out all life on the planet. ## 10. Solaris (2002) Steven Soderbergh's 2002 Solaris stars George Clooney as a psychologist investigating a space station where his late wife appears alive. > Soderbergh's Solaris is both his most understated and boldest project, using the mysteries of the cosmos to explore its emotional themes. ## 9. Moon Duncan Jones' 2009 Moon follows Sam Rockwell as a lunar miner who hallucinates and discovers his doppelganger. > The idea that the Moon could be mined heavily for helium-3 is rooted in fact, while the technology is never particularly outlandish. ## 8. Silent Running 1972's Silent Running shows a botanist defending trees on a spaceship from corporate overseers who want to destroy the biomes. > Of all the movies on this list, Silent Running is the one with the most pointed sociopolitical commentary. ## 7. Her (2013) Her (2013) follows Theodore Twombly's relationship with his AI assistant Samantha in near-future Los Angeles. > The movie's premise feels entirely plausible while also being prescient in the decade prior to the widespread proliferation of artificial intelligence. ## 6. Contact (1997) Contact (1997) depicts astronomer Ellie Arroway detecting extraterrestrial signals and the global reaction to the discovery. > Jodie Foster brings that thoroughly human response to the subject matter, while her character guides audiences through the story. ## 5. Project Hail Mary Project Hail Mary (2026) follows molecular biologist Ryland Grace searching for a sun-saving solution after a cosmic threat. > Project Hail Mary improves upon Andy Weir's book in key ways, streamlining the story and quietly discarding its more superfluous sci-fi elements. ## 4. Interstellar Interstellar (2014) follows astronaut Coop's mission to save humanity from Earth's dust storms using a gravity-based spacecraft. > Everything from planets undergoing significant time dilation to the gravity equation back on Earth all feel feasible. ## 3. Ex Machina Ex Machina (2014) follows programmer Caleb Smith testing the sentience of an android named Ava. > The movie avoids green screen use, preferring practical effects and sets for its execution. ## 2. The Martian The Martian (2015) follows astronaut Mark Watney surviving alone on Mars after a dust storm evacuates his team. > Andy Weir gave the 2015 adaptation of The Martian his seal of approval, and we do too. ## 1. 2001: A Space Odyssey 2001: A Space Odyssey (1968) traces humanity's evolution through a monolith that triggers an alien intelligence. > Given Kubrick's exhaustive attention to detail and Clarke's scientific acumen, 2001: A Space Odyssey is as hard as the genre gets on film. ## Key takeaway 15 hard sci-fi movies ranked by scientific plausibility and narrative depth.
