Time travel, extraterrestrial life forms, and highly advanced technology are just a few familiar concepts in the science-fiction genre, and with few to no boundaries, the genre has branched out over the years into several popular subgenres, specifically hard science fiction. Unlike its core counterpart, hard science fiction requires scientific accuracy and a logical scenario that could be entirely plausible in the near or distant future of society.

While many science-fiction films are partially rooted in the subgenre, including Blade Runner, and The Fifth Element, there are some movies like Children of Men, Gattaca, and Her that surpass others and qualify as solid hard science-fiction films. Out of countless titles, such as Ridley Scott's The Martian and 2001: A Space Odyssey, these are the 20 best hard science-fiction movies, ranked.

25 'THX 1138' (1971)

Before audiences traveled to a galaxy far, far away, George Lucas made his directorial debut with the science fiction movie THX 1138, which he also co-wrote with Walter Murch. The movie is set in a dystopian future society where humans now live in underground cities and are forced by humanoids to take medication to suppress their emotions and free will. When THX 1138 (Robert Duvall) and LUH 3417 (Maggie McOmie) stop taking their medication, they not only realize the truth of their existence but also fall in love along the way.

The concept of THX 1138's treatment of human biology, psychology, and reproduction as technical processes carried out by an authoritarian system is what ultimately makes it a hard science-fiction movie that is often unfairly overlooked. The first version of the movie was created by Lucas in 1967 as a student film project while attending USC School of Cinematic Arts, and he eventually expanded it into a feature-length film for Warner Bros., which never received a home media release. After the massive success of Star Wars: Episode IV — A New Hope, Warner Bros. released a restored version of the film followed by a director's cut in 2004.

24 'The Vast of Night' (2019)

The Vast of Night is an intriguing hard science fiction movie and cryptic mystery that takes place during the 1950s in New Mexico and follows a switchboard operator, Fay Crocker (Sierra McCormick), and a radio DJ, Everett Sloane (Jake Horowitz), as they try to uncover the truth behind a mysterious frequency and pinpoint its origin. The movie is loosely based on the Kecksburg UFO Incident from 1965 and the Foss Lake disappearances in 1969 and 1970, which were solved in 2013.

The movie earned generally positive reviews from both audiences and critics, with many praising both McCormick and Horowitz's performances, but despite its success, The Vast of Night doesn't always get the recognition it deserves. While some may argue that the movie is rooted more in the soft science fiction genre, The Vast of Night does have several notable hard sci-fi elements, specifically its heavy reliance on technology instead of supernatural tropes, that rightfully earn it a place on this exclusive list of solid hard science fiction movies.

23 'Robot & Frank' (2012)

Robot And Frank in the woods as Frank uses a pair of binoculars

Frank Langella stars in the 2012 science fiction comedy Robot & Frank as a former jewel thief, Frank Weld, who lives alone and suffers from dementia. When he receives a robot as a gift from his son, Hunter (James Marsden), he doesn't turn to the technical being as a new companion or nurturing caregiver but instead decides to recruit the robot as his newest partner and introduces it to a life of crime.

Considering the continuing advancement of technology and AI, the premise of Robot & Frank, in some sense, already exists in our society in various other forms. We may not have widespread access to robot companions, but there are already dozens of programs and systems similar to those in Robot & Frank that either help people with their daily tasks or assist with managing medical conditions. Despite some mixed reviews, Robot & Frank was a general success and earned praise from critics and reputable outlets, including Kenneth Turan of the Los Angeles Times, who called the film "charming, playful, and sly."

22 'The Andromeda Strain' (1971)

Robert Wise's The Andromeda Strain is an essential hard sci-fi flick based on the 1969 novel of the same name, written by Michael Crichton, and follows a group of scientists who are tasked with investigating a deadly organism with extraterrestrial origins that wiped out the entire population of a small town in New Mexico. The movie features innovative special effects created by Douglas Trumbull, who is known for his work on other iconic sci-fi films, notably Stanley Kubrick's 2001: A Space Odyssey, Star Trek: The Motion Picture, and Close Encounters of the Third Kind.

In 2003, the Infectious Diseases Society of America credited The Andromeda Strain as the most significant and scientifically accurate movie about a deadly and unknown virus, noting the details surrounding the discovery, investigation, and identification of a virus as uncanny. On top of the scientific process, the movie also features advanced technology that has since been made into a reality, ultimately boosting the film's reputation as a top-tier contribution to the subgenre. The Andromeda Strain earned generally favorable reviews and was a minor box office hit, becoming the sixteenth highest-grossing movie of the year.

21 'High Life' (2018)

Two astronauts, one man and one woman look through the window towards the sun aboard their spacecraft

A group of criminals serving death sentences opt out of execution and are sent on a dangerous mission into space to collect alternative energy from a black hole while also being experimented on by a scientist, Dibs (Juliette Binoche). When one prisoner, Monte (Robert Pattinson), and his young daughter are the only survivors, they must rely on each other to survive the dire mission and avoid being sucked into the massive black hole.

High Life is a visual spectacle of a hard science-fiction film that also deals with rather morbid themes but also centers around the physics theory known as the Penrose Process, which theorizes how energy can be extracted from the region around a black hole. The film's director, Claire Denis, along with the cast and crew, all traveled to visit the European Space Agency's Astronaut Centre, where they worked with several scientists, including ESA's astronaut instructor, Laura André-Boyet, and physicist and black hole expert, Aurélien Barrau. High Life received positive reviews from audiences and critics, including Roger Ebert.com's Matt Zoller Seitz, who described the film as "tailor-made for viewers who like science-fiction in a cryptic 1970s arthouse mode."

20 'Destination Moon' (1950)

Warner Anderson and Dick Wesson in Destination Moon (1950)

In the Mojave Desert, a group composed of an aerospace scientist (Warner Anderson), a former Air Force pilot (Tom Powers), and an industrialist (John Archer) make the daring plan to travel to outer space and land on the moon. After they construct and successfully launch a spacecraft, the men think their mission could actually be successful, but when an error in the calculations of power proves not to be enough to escape the moon's gravitational pull, the men's lives are put in serious danger.

Destination Moon was the first U.S. science-fiction film to involve space travel's scientific and engineering challenges and portray what a crew's mission to the moon may look like. Science fiction author Robert A. Heinlein was hired as a consultant to work on the film's screenplay and also help develop the visual aspect of the film. While it's not a highly advanced hard science-fiction film, Destination Moon was ahead of its time and incredibly vital to the hard sci-fi subgenre by ultimately paving the way for future space travel films.

19 'Colossus: The Forbin Project' (1970)

In a secret location in the Rocky Mountains, Dr. Charles Forbin (Eric Braeden) has developed a large supercomputer called "Colossus," which is designed to detect and ensure the country's safety against any nuclear attacks. While the invention is monumental for national security, Colossus eventually connects with a Russian computer known as "Guardian" and the two begin a secret dialogue that could prove to be dire for the entire world.

Colossus: The Forbin Project is a thrilling hard sci-fi film based on the 1966 science-fiction novel, Colossus, written by D.F. Jones. The film is one of the first to address the development and rise of Artificial Intelligence as well as the dangers it could present for humankind. With today's advancement of A.I., the warning featured in Colossus: The Forbin Project begins to appear entirely plausible. Despite centering around a somber subject, Colossus: The Forbin Project does have its moments of humor and satire woven through scientific fact, which deems it to be one of the best hard sci-fi films.

18 'Project Hail Mary' (2026)

Ryan Gosling in a ship in 'Project Hail Mary'

Ryan Gosling stars in the adaptation of Andy Weir's 2021 novel, Project Hail Mary, as a middle school science teacher, Ryland Grace, who wakes up alone on a spaceship with no recollection of who he is or how he ended up there. As his memory slowly begins to come back, he soon remembers that he was sent on a mission to figure out how to stop a mysterious substance that has been slowly causing the sun to die out, leaving the fate of humankind solely in his hands.

Project Hail Mary is one of the latest hard science fiction hits that centers around the interstellar threat of an Astrophage, which is a microscopic, single-celled alien organism that is capable of absorbing an incredible amount of energy. Unlike other hard science-fiction movies, Project Hail Mary doesn't strive to deliver a visual spectacle with intense action and suspense, but instead, it gives audiences a thrilling adventure with a brilliant balance of intelligence and heart, making it one of the most unique and refreshing hard science-fiction movies in recent years.

17 'Gravity' (2013)

Sandra Bullock stars as a medical engineer, Dr. Ryan Stone, who is on her first shuttle mission with veteran astronaut, Matt Kowalsky (George Clooney), who is on his final flight into space. While the two are conducting a routine space walk, disaster strikes as their spaceship is destroyed, leaving them stranded among the stars. With no link or connection to Earth, Stone and Kowalsky begin to panic, losing all hope of survival, but they eventually realize that if they have any chance of being rescued, they must travel further into space.

Gravity is a nail-biting hard science fiction thriller that doesn't shy away from the real risks and dangers of space travel. While the film's director, Alfonso Cuarón, has admitted the film takes some scientific liberties, Gravity has still been praised for its overall physical properties and the realism surrounding the film's premise. According to NASA astronaut Michael J. Massimino, nothing appears out of place or missing from Gravity, noting specifically a one-of-a-kind wire cutter featured in the film which is also used in real-life spacewalks. The movie earned ten Oscar nominations, such as Best Picture and Best Actress, ultimately winning seven, including Best Director, Best Original Score, and Best Cinematography.

16 'Children of Men' (2006)

Theo escorting Kee through a crowd in Children of Men

In the year 2027, two decades of infertility presents the possibility of the human population becoming extinct, leading to society on the brink of collapsing. When a civil servant, Theo Faron (Clive Owen), crosses paths with a young asylum seeker, Kee (Clare-Hope Ashitey), she reveals to him that she is the only pregnant woman in the world, prompting Faron to save her from experimentation and help her escape to safety.

The hard science-fiction thriller, Children of Men, is based on the 1992 novel, The Children of Men, written by P.D. James, and also stars Julianne Moore, Charlie Hunnam, and Michael Caine. The movie is a non-stop cycle of intensity and suspense filmed in a documentary style that adds more authenticity compared to other hard science-fiction films. Children of Men serves as a plausible background to a massive infertility crisis but also how society and individuals would react to such a phenomenon. The movie earned overall positive reviews from critics, including renowned film critic Roger Ebert, who gave the film four or four stars, praising the film's convincing backdrop as well as serving as a valid cautionary tale.
