‘The Thing’ (1982)
IMDb Rating: 8.2/10
If there were to exist a hypothetical Mount Rushmore of horror movie directors, John Carpenter would have to be right up there. We’re talking about one of the most revolutionary, groundbreaking, and brilliantly subversive horror auteurs in the genre’s history. For proof, one needn’t look any further than The Thing, Carpenter’s take on John W. Campbell Jr.‘s 1938 novella Who Goes There?
It’s one of the best sci-fi thriller masterpieces of all time, simultaneously working as a chilling horror classic and a reflection of the paranoid psyche of Cold War-era America. Over four decades after its release, the film is still being dissected and praised by cinephiles on IMDb, who confidently call it one of the greatest horror films of all time. —Diego Pineda Pacheco

‘Jurassic Park’ (1993)
IMDb Rating: 8.2/10
Steven Spielberg is the father of Hollywood blockbusters, and he has reigned supreme in that space since the mid-’70s—but it was the ’90s that were the most lucrative decade for his filmography in history. It was all thanks to masterpieces like Jurassic Park, an engrossing adaptation of Michael Crichton‘s 1990 novel.
Here, Spielberg balances suspense, emotion, thought-provoking thematic work, and jaw-dropping special effects like the absolute pro that he has always been. Jurassic Park is nothing short of one of the best films of the 1990s, a gem that remained the highest-grossing film of all time for four years and is still one of the highest-rated on IMDb. —Diego Pineda Pacheco

‘Project Hail Mary’ (2026)
IMDb Rating: 8.2/10
Andy Weir has firmly established himself as one of the most enticing hard science fiction authors currently working, and his 2021 novel Project Hail Mary only further enshrined him on that throne. Along came Phil Lord and Chris Miller and fittingly turned the story of Grace and Rocky’s unlikely friendship into one of the greatest hard sci-fi films of all time.
Project Hail Mary can already be counted among those modern sci-fi movies that will be classics. It’s everything that a hard sci-fi space opera should aim to be: faithful enough to scientific rigor without ever sacrificing entertainment value. It’s colorful, it’s emotional, it can be funny whenever it needs to be, and it’s full of the same kind of wonder and movie magic that IMDb users love to see in this genre. — Diego Pineda Pacheco

‘A Clockwork Orange’ (1971)
IMDb Rating: 8.2/10
Set in a dystopian version of England, director Stanley Kubrick’s A Clockwork Orange depicts a world where violence and delinquency are part of the norm. It follows Alex (Malcolm McDowell) and his “Droogs” as they spread chaos and hurt others, which leads to the sci-fi aspect of the film, where the protagonist undergoes extreme rehabilitation using technology that changes his behavior. It’s a strange blend of surrealism and sci-fi elements that fans appreciate, giving it such a high rating.
A Clockwork Orange immerses viewers in a disturbing world that blurs the line between right and wrong. It questions the very nature of evil itself through Alex’s story, which is inevitably linked with political commentary about the extent of control the government can have over individuals’ free will.
21
‘Metropolis’ (1927)
IMDb Rating: 8.2/10
A great sci-fi movie that’s over 100 years old, Metropolis is a groundbreaking and influential masterpiece directed by Fritz Lang. Its story is centered on a privileged individual who is appalled by the newfound knowledge of the harsh conditions the working class is subjected to on a daily basis.
Metropolis is a timeless classic that’s also eerily accurate, as the “future” it depicts isn’t too far off from reality. Its innovative set design is fascinating to watch today, especially when audiences consider that Lang used miniature buildings to bring cityscapes to life.
20
‘Cat City’ (1986)
IMDb Rating: 8.3/10
As it turns out, it’s not just the mainstream movies on IMDb’s official Top 250 highest-rated movies that are among the highest-rated sci-fi films on the site: There are also masterpieces as criminally underappreciated as the Hungarian adult animated gem Cat City, which still doesn’t have enough user ratings to enter the official IMDb Top 250.
It absolutely deserves to get there, however, because as far as adult animation made for the big screen goes, it doesn’t get much better than Cat City. It’s one of the most near-perfect animated movies that nobody remembers anymore, a wildly creative and funny cult classic full of thrilling moments, stunning hand-drawn designs, and clever social satire. —Diego Pineda Pacheco

‘Star Wars: Episode VI – Return of the Jedi’ (1983)
IMDb Rating: 8.3/10
The iconic third installment in the original Star Wars trilogy, Return of the Jedi depicts Luke Skywalker’s (Mark Hamill) continued struggle against the Galactic Empire, alongside the new couple Han Solo (Harrison Ford) and Princess Leia (Carrie Fisher), who embark on a misadventure of their own.
The perfect continuation of the Skywalker Saga, Return of the Jedi captivated audiences around the globe and became a massive blockbuster. It was the highest-grossing film of the year after earning a whopping $475 million at the global box office, further establishing the widespread influence of the sci-fi franchise.
18
‘Eternal Sunshine of the Spotless Mind’ (2004)
IMDb Rating: 8.3/10
Eternal Sunshine of the Spotless Mind, directed by Michel Gondry, is an emotional and effective breakup movie that conveys the sorrow, bewilderment, and regret that frequently come with the end of a relationship. Set in a version of the world in which it is possible to forget things thanks to new memory-erasing tech, it follows a couple, Joel (Jim Carrey) and Clementine (Kate Winslet), as they navigate the confusing line between needing to remember and wanting to forget.
The film is a beautiful and meaningful depiction of what it is like to lose someone important in one’s life. With its weird dream sequences and emotional lines, the film captivates, entertains, and moves to tears all at once. Joel’s eventual desperation to cling to the memory of Clementine will definitely strike a chord with viewers, who may not have the same opportunity for a second chance as the pair does in the film. Its amazing IMDb score of 8.3 makes it a perfect fit on the list of best sci-fi movies.
17
‘2001: A Space Odyssey’ (1968)
IMDb Rating: 8.3/10
Director Stanley Kubrick‘s 2001: A Space Odyssey is an iconic entry in the genre that needs no introduction. Its ambitious storyline spans thousands of years and is anchored on the discovery of a monolith that a crew is sent out to investigate. Alongside the now-legendary AI HAL 9000, they soon find themselves in mind-bending situations.
With its stunning visuals, brilliant use of music, and profound narrative, 2001: A Space Odyssey became the quintessential space opera that highlighted the viability of the genre. Although it wasn’t initially appreciated as the masterpiece that it is, Kubrick’s film is recognized today as a classic that served as a genre-defining moment in cinematic history.
16
‘Dune: Part Two’ (2024)
IMDb Rating: 8.4/10
Before the 2020s rolled in, no one could have possibly blamed fans of Frank Herbert‘s Dune, one of the greatest and most important works of sci-fi literature in history, for thinking that it was impossible to live up to the novel’s legacy in cinematic form. That was before Denis Villeneuve entered the scene. 2021’s Dune was great, but it’s Dune: Part Two that’s bound to go down in history as one of the greatest sci-fi blockbusters of the first half of the 21st century.
It’s an action-adventure masterpiece through and through, and even calling it one of the best sci-fi movies of the last 10 years feels like a bit of an understatement. The way Villeneuve’s vision blends with Herbert’s imagination here is jaw-dropping, offering plenty of unforgettable moments of excitement, amazement, emotion, and purely epic science fiction. —Diego Pineda Pacheco
