The ’70s were a turning point for sci-fi in cinema. Before that, the genre felt more like playtime than serious storytelling, but in this decade, movies started bringing bolder ideas, sharper critiques, and visuals that still impress today considering their time. Some filmmakers began questioning the real world through dystopias, space adventures, and all kinds of different stories, without being afraid to shock or provoke. The result were films that not only still entertain, but also make us think—about technology, society, and morality. In the end, many of them showed us that sci-fi can (and should) be way more than just special effects.

With that in mind, here are 4 of the ’70s sci-fi movies that somehow predicted life like no other, standing out for being ahead of their time. Even today, they remain highly relevant, widely discussed, and considered brilliant across generations. If the genre ever became important for cinema, it’s because of these films.
4) Soylent Green
Soylent Green is one of those movies that feels like it came straight out of a futuristic conference on climate crises and social inequality. It’s not just a dystopian thriller, but a brutally direct critique of consumerism and environmental negligence that, almost 50 years later, still hits uncomfortably close to home. The story follows Detective Thorn (Charlton Heston) as he investigates the death of a Soylent Corporation executive, only to uncover that the famous “Soylent Green” is actually made from human beings. But that plot twist is just the tip of the iceberg in a story that challenges what it means to be moral and how we exploit the planet and each other.
The film also nails a dark, noir-style aesthetic that heightens the sense of desolation, while forcing audiences to confront a reality no one wanted to imagine: overcrowded cities, extreme poverty, and dwindling natural resources. For a movie from the ’70s, the way Soylent Green tackles issues that feel so contemporary is seriously impressive.
3) A Clockwork Orange
A film that still manages to unsettle audiences today is A Clockwork Orange—and it seems to do so intentionally. The plot follows Alex (Malcolm McDowell), a young delinquent who leads a gang and undergoes an experimental psychological treatment to eliminate his violent tendencies. On its own, that’s an interesting premise, but director Stanley Kubrick takes it further by turning violence into something almost hypnotic, forcing viewers to think about social control and free will. The film doesn’t just shock visually; it makes you question how far society can go in shaping human behavior without destroying individuality.
For a movie from the ’70s, the audacity of A Clockwork Orange is almost insane, and that’s exactly where it shines timelessly. The debate over freedom versus conformity hasn’t aged a bit. Its impact stretches far beyond the story itself, making the movie a deeply unsettling study of morality and power.
2) Alien
When it comes to sci-fi and horror together, plenty of films stand out, but Alien takes it to another level. Even though it became a franchise, the original movie is the one that fits this list best. The story follows the crew of the Nostromo as they investigate a mysterious signal and encounter a deadly alien organism. From there, it turns into a survival nightmare, featuring one of cinema’s most unforgettable protagonists: Ripley (Sigourney Weaver). The film’s suspense is suffocating, and that’s exactly where its power lies.
Alien builds fear slowly, creating a sense of vulnerability that few movies, especially from the ’70s, could pull off. Even today, the creature design and relentless tension still impress. On top of that, Weaver redefined what a sci-fi heroine could be, giving her character intelligence, strength, and resilience that made her iconic. The film also sneaks in some sharp points about corporate greed and how human life gets undervalued.
1) Star Wars: Episode IV – A New Hope
Even more than 40 years later, Star Wars: A New Hope remains a benchmark for sci-fi storytelling and adventure, earning its place as a true legend. The story follows Luke Skywalker (Mark Hamill), a young farm boy who gets caught up in the Rebel Alliance’s fight against the Galactic Empire. Here, George Lucas did more than deliver groundbreaking effects—he built an expansive universe full of culture, politics, and moral conflict, one that still manages to influence modern cinema. It’s hard to overstate the movie’s impact on the way space stories are told even today.
Star Wars is a hugely successful franchise, but none of it would exist without A New Hope. It’s a classic hero’s journey, but it stands out for its complex, relatable characters. On top of that, the film packs action, drama, and its own mythology, all while introducing special effects that were revolutionary back in the ’70s. It’s ahead of its time because it showed that a space adventure could be grand, smart, emotional, and innovative all at once.
