10 Best Sci-Fi Movies of the 1970s, Ranked

The 1970s produced many innovative science fiction films that greatly influenced the blockbuster genre we know today. Coming just after World War II, these movies reflected a shift in how Hollywood and studios worldwide created science fiction. By the ’70s, anxieties about the future – including potential disasters and oppressive governments – were growing. This atmosphere allowed filmmakers to explore possible futures and warn audiences about the potential consequences of the world’s direction.

With so many landmark films in the decade, here is a look at the best sci-fi movies of the 1970s.

10) The Man Who Fell to Earth

David Bowie first appeared on screen in the science fiction film The Man Who Fell to Earth, directed by Nicholas Roeg. The film features Bowie as an alien who comes to Earth seeking water to save his home planet. However, his character, Thomas Jerome Newton, gets caught up in Earth’s temptations and ends up staying much longer than planned. By the time he’s ready to help his people, the U.S. government intervenes to stop him. The movie is a thought-provoking story about how even highly intelligent beings can be corrupted by Earth’s vices, and how this often leads to failure.

9) Silent Running

Directed by Douglas Trumbull – known for his special effects work on films like 2001: A Space Odyssey and Close Encounters of the Third Kind – the 1972 film Silent Running presents a future where Earth’s forests are gone due to environmental neglect. Scientists attempt to preserve plant life by sending it into space, hoping to one day restore Earth. When a scientist receives orders to destroy the plants and return to regular duties, he rebels, saving them and going into hiding. This thought-provoking sci-fi film offers a cautionary tale about the importance of environmental responsibility and planning for the future.

8) Mad Max

Originally released in 1979, Mad Max launched a film series that continued with new installments all the way up to 2024. While fans of the explosive Mad Max: Fury Road might be surprised by the original, it’s still a thrilling sci-fi action movie. It focuses on Mel Gibson as Max, seeking vengeance against a motorcycle gang who killed his loved ones. You can definitely see the seeds of the later, larger-scale films in this gritty revenge story, which takes place in a post-apocalyptic world.

7) Logan’s Run

Logan’s Run is a classic science fiction action film set in the year 2274. In this future, humanity lives inside a domed city controlled by a powerful computer. To control population, everyone is required to participate in a ritual called the “Carrousel” on their 30th birthday, which is a euphemism for execution, with the promise of being ‘Reborn.’ Some believe there’s a life outside the city, called the Sanctuary, and those who try to find it are labeled ‘runners’ and hunted by special agents called Sandmen. Logan is a Sandman tasked with discovering the truth about the Sanctuary. Released in the 1970s, this film is considered one of the best examples of dystopian science fiction from that era.

6) Soylent Green

The 1973 film Soylent Green depicts a bleak future world facing ecological collapse and overpopulation. While the story follows a detective, played by Charlton Heston, investigating a murder in the year 2022, it’s the movie’s shocking twist – far more famous than the plot itself – that truly sets it apart. The film portrays a world where dying oceans and extreme humidity are killing people, and the detective discovers a horrifying secret behind a new artificial food product created by the Soylent Corporation.

5) Superman

By 2026, some people are starting to wonder if audiences are getting tired of superhero movies, even though they still make a lot of money. There are concerns that too many comic book films are being made. This wasn’t the case in the 1970s – before 1978, no one had ever attempted a large-scale superhero movie for theaters. That changed with Richard Donner’s Superman. While the character had appeared on film before, nothing compared to this movie’s scale. It proved to Hollywood that superhero films could be successful in cinemas, though it wasn’t until Batman in 1989 that another film replicated that success.

4) Invasion of the Body Snatchers

It’s common for movie fans to dislike remakes, but they aren’t always bad. In just the last ten years, at least four remakes have actually been better than the originals: Invasion of the Body Snatchers, The Thing, The Fly, and The Blob. Invasion of the Body Snatchers led the way, offering a clever science fiction thriller reflecting Cold War anxieties. The story centers on an alien invasion where humans are replaced by duplicates grown in pods. Featuring stars like Leonard Nimoy, Donald Sutherland, and Jeff Goldman, and even a brief appearance by Kevin McCarthy from the original film, it’s widely considered one of the greatest sci-fi remakes of all time.

3) Close Encounters of the Third Kind

Steven Spielberg is known for his incredibly diverse and successful films, spanning many genres and becoming classics. Following the blockbuster horror film Jaws, he ventured into science fiction with the compelling drama Close Encounters of the Third Kind. Starring Richard Dreyfuss as a father captivated by the possibility of extraterrestrial life, the film follows his determined search for a potential spacecraft landing on Earth, even if it means straining his family relationships. Close Encounters earned Spielberg his first Academy Award nomination and is still considered a landmark achievement in science fiction cinema.

2) Alien

As a huge cinema fan, I always say that the Alien franchise is one of the greatest sci-fi horror series ever created, and it all started with the original film in 1979. While the sequels definitely leaned into more action and complex sci-fi ideas, the first Alien was pure horror – honestly, it felt like a classic haunted house story, but set on a spaceship! Sigourney Weaver is incredible as Ellen Ripley, a crew member on a salvage ship sent to find a lost vessel, only to discover terrifying alien creatures on board. It’s basically a really intense, claustrophobic slasher film… with an alien! And it kicked off a franchise that’s still captivating audiences today.

1) Star Wars

When George Lucas’s Star Wars came out in 1977, the film studio didn’t expect much success. Lucas drew inspiration from the classic storytelling structure called the Hero’s Journey and the films of Akira Kurosawa. Crucially, he also negotiated to retain the rights to all Star Wars merchandise, which ultimately made him incredibly wealthy. This is because Star Wars quickly became a huge franchise, expanding into additional movies, comics, toys, television series, and countless other products. The original film is still considered one of the most important and influential science fiction movies ever made, and it paved the way for many of the space-based stories we see today.
