45 Best Sci-Fi Movies of All Time, Ranked

The science fiction genre has been one of the most consistently thrilling to explore throughout the history of cinema. The way a visual medium like film can depict futuristic worlds or alternate realities means that almost anything that can be imagined can be depicted on-screen. Since the silent era, filmmakers have been using the medium to their advantage, commenting on humanity’s present and hypothesizing about its future through the science-fiction genre.

There are countless great sci-fi movies that have been released since the birth of cinema as an art form, and it’s ultimately futile to try and name every single amazing one. There are simply too many top sci-fi movies, and it’s a genre that’s still thriving, with new potential classics released seemingly every year. The following are among the best of the best from the sci-fi genre, being classics for their entertainment value, excellent technical qualities, and historical significance, and are ranked below in order from great to greatest.

45 ‘Beyond the Infinite Two Minutes’ (2020)

Directed by Junta Yamaguchi

Beyond the Infinite Two Minutes is one of the best Japanese movies of the last few years, and also stands as one of the most entertaining and rewatchable sci-fi films in recent memory. It deals with an initially limited form of time travel that involves a screen that shows footage from two minutes in the future, which leads to wonder, fortunes, and eventual chaos for the people who discover this strange phenomenon.

Made on a limited budget and filmed in a way that makes it appear like a single take, Beyond the Infinite Two Minutes is quite dazzling for such a small-scale movie, and endlessly inventive/clever. It’s got an infectious spirit and is overall the kind of movie that will provide significant entertainment value for just about anyone who seeks it out.

44 ‘Voyage of the Rock Aliens’ (1984)

Directed by James Fargo

Calling Voyage of the Rock Aliens ridiculous would be underselling it to a considerable extent, but that’s obvious, given it’s literally called Voyage of the Rock Aliens. It functions as a surprisingly good (and wonderfully cheesy) musical, a comedy that feels like a throwback to teen movies of the 1950s and ‘60s, and a sci-fi movie about aliens coming to Earth and trying/failing to fit into life on the planet.

Voyage of the Rock Aliens is a cult movie through and through, and one of the most 1980s-feeling movies to come out of the decade. It’s sloppy, the music probably isn’t for everyone, and watching it is an undeniably chaotic experience, but there’s so much energy and vibrancy to the whole thing that it’s hard to resist, particularly for any sci-fi fans who have a particular fondness for science fiction of the B-movie variety.

43 ‘August in the Water’ (1995)

Directed by Gakuryu Ishii

Blending some fantasy/supernatural elements with an odd yet compelling science fiction story, August in the Water is both a unique and underrated film. It focuses on several teenagers living in the Japanese city of Fukuoka, and explores what happens when one of them – a young girl – begins to develop mysterious powers, all the while strange occurrences continue to happen to the city’s population.

August in the Water isn’t exactly clear about the story it’s telling, nor is it particularly narrative-centered in the first place, but it is undeniably atmospheric and provides a distinct look/feel. It’s broad and open-ended enough to leave many things up to interpretation, and even those who get a bit lost in August in the Water will still be able to appreciate its visual style and singular tone.

42 ‘Poor Things’ (2023)

Directed by Yorgos Lanthimos

Poor Things was surprisingly successful for such an odd and offbeat movie, but those willing to get immersed in something a little different will likely find the film to be a rewarding one. It’s a surprisingly funny and always visually dazzling sci-fi movie about a woman who’s brought back to life, and then goes on a strange and sometimes alarming journey, rediscovering life and effectively coming of age for a second time.

Yorgos Lanthimos is perfectly suited to this kind of story and this sort of style, with the cast also shining while digging into the strange material they’ve been given, especially Emma Stone in the lead role, who won a second Oscar for her performance. Poor Things is a movie that’s a highlight of the 2020s so far, and feels like the sort of sci-fi movie that will one day be held up as a classic.

41 ‘Godzilla Minus One’ (2023)

Directed by Takashi Yamazaki

Speaking of relatively recent science fiction movies that already feel like modern classics, Godzilla Minus One was one of the biggest surprises of 2023, and one of the best Godzilla movies of the past couple of decades. It takes things back further in time than any other movie in the long-running series, taking place right after World War II, following people who are already struggling with surviving the war’s aftermath when the titular monster emerges and makes life even more difficult.

All the monster action in Godzilla Minus One is exciting and satisfying, but it’s the human characters – and their story – that give it the edge overall, and make it function as a genuinely good drama on top of being a kaiju movie. It’s very approachable and a perfect entry point into the series, particularly for anyone who’s more familiar with the American Godzilla movies and has yet to watch any from Japan.

Godzilla Minus One is currently not available to stream, rent, or purchase in the U.S.

40 ‘Woman in the Moon’ (1929)

Directed by Fritz Lang

The most famous sci-fi movie directed by Fritz Lang came out before Woman in the Moon (more on it a little down the line), but this 1929 shouldn’t be overlooked just because it’s his second-best science fiction film. It’s a remarkable cinematic achievement, considering it’s close to a century old, and remains an engaging film about an expedition to the moon – led by a scientist – in search of gold.

Now, given its age and premise, there are aspects here that feel more fictional than ever in a post-moon landing world, but considering Woman in the Moon predated humanity actually reaching the moon by 40 years, the sci-fi movie’s predictions were still impressive. It’s also got inventive special effects and a surprisingly well-told and dramatic story, making it one of the best – and most underrated – films of the silent era, sci-fi or otherwise.

39 ‘Electric Dreams’ (1984)

Directed by Steve Barron

Perhaps feeling more like a quirky and heartfelt romantic comedy than a full-on science fiction movie, Electric Dreams does still center around an advanced computer that begins to fall for a young woman. The computer, in a sense, enters into a love triangle of sorts with the young man who purchased it, given the man also has feelings for the same woman, yet is too shy to approach her.

Electric Dreams then becomes like a sci-fi take on Cyrano de Bergerac, with the computer being Cyrano, helping a more conventional romantic partner while also having his own intense feelings of love toward a romance that can’t be. It might sound ridiculous, and Electric Dreams is kind of silly, but it’s also got a sincerity to it that makes it hard to resist. The cynical need not apply, but those open to the film’s odd charms might be it to be one of the more underrated sci-fi flicks of the ‘80s.

38 ‘Godzilla vs. Destoroyah’ (1995)

Directed by Takao Okawara

Throughout the remarkably long history of the Godzilla series, the titular monster has fought many other powerful and intimidating titans. For as mighty as foes like King Kong and King Ghidorah have been, there’s an argument to be made that his most powerful enemy wasn’t even a “King,” and that it was actually Destoroyah, a monster who’s only been featured in one Godzilla film to date: 1995’s Godzilla vs. Destoroyah.

Notable for being one of the most intense, frightening, and moving films in the entire series, Godzilla vs. Destoroyahserves as a grand finale for Godzilla’s Heisei era, which comprised seven movies released between 1984 and 1995 that told a surprisingly continuity-heavy narrative spanning just over a decade. It might not be as powerful outside the context of the series/era, but it’s nevertheless one of the finest of all Godzilla films, and stands as a great work of science fiction as a result.

37 ‘Star Wars: The Last Jedi’ (2017)

Directed by Rian Johnson

There are certainly things to criticize when it comes to the most recent Star Wars movies, largely owing to the messily constructed and planned-out sequel trilogy. Yet buried within this flawed trio of films is a genuinely great sci-fi movie that itself is divisive: Star Wars: The Last Jedi. This eighth entry in the Skywalker Saga has passionate fans and vocal detractors, but that seemed inevitable, given it was directed by the guy who was behind what some people call the worst Breaking Bad episode (“Fly”) and what many call the best Breaking Bad episode (“Ozymandias”).

Star Wars: The Last Jedi brings Luke Skywalker back into the fold, taking his character in interesting directions while ultimately having him live up to his legacy by the film’s end. Other aspects of the film seem odd or disappointing at first, but all of it comes together in an interesting way by the end. It reckons with the history of Star Wars, celebrates it, and critiques it all at once, and does so while also being tremendously moving, emotionally speaking, and spectacular, from a visual standpoint.

36 ‘Forbidden Planet’ (1956)

Directed by Fred M. Wilcox

Of all the science fiction movies made during the 1950s, Forbidden Planet is undeniably up there with the most iconic. It follows a crew of space travelers who go in search of another exploration party that’s been missing for years, only to make some unusual and startling discoveries during their attempted rescue/recovery mission.

It has an undeniably distinct aesthetic that’s inextricably tied to the look and feel of classic ’50s sci-fi. It’s also notable for having what’s perhaps Leslie Nielsen‘s best-known non-comedic role, given his career was rejuvenated in the 1980s thanks to starring in a range of iconic parody/spoof movies. Some may find Forbidden Planet to be a little old-fashioned and maybe even slightly cheesy by today’s standards, but it’s the aesthetics on offer here that might also prove charming to others.

35 ‘Inception’ (2010)

Directed by Christopher Nolan

Inception certainly was a cinematic highlight of 2010, and it had some pretty tough competition that year, too. It’s Christopher Nolanblending his affinity for action and science fiction in one, and making this blend go down smoothly with an engaging premise that’s about performing a reverse heist within a target’s subconscious, making it function well as an action/thriller movie as well as a piece of science fiction.

It’s a movie that throws tons of fairly complex ideas at the viewer in rapid succession, and so if there’s one criticism that can be thrown Inception’s way, it’s that it’s a little heavy on the exposition at times. But the action-packed scenes serve well as payoffs, and the narrative does find interesting and sometimes unexpected places to go beyond the explanatory dialogue-heavy opening act.

34 ‘Under the Skin’ (2013)

Directed by Jonathan Glazer

Those who prefer their sci-fi conventional may want to steer clear of Under the Skin, or approach it very cautiously, given it’s another strange, haunting, and unapologetic film directed by Jonathan Glazer. It’s essentially an arthouse take on a story about an alien coming to Earth, perhaps being for the 2010s what the equally bizarre and captivating The Man Who Fell to Earth was for the 1970s.

Scarlett Johansson plays the alien at the center of Under the Skin, and much of the movie is about this life form – after taking on a human appearance – stalking and capturing various men who become prey. It offers little by way of easy answers, and much of the film is up to the interpretation of the individual viewer, for better or worse (probably more better, so long as you know roughly what you’re in for).

33 ‘Avatar’ (2009)

Directed by James Cameron

James Cameron might’ve referred to himself as the king of the world after his 1997 film Titanic swept the Oscars, but it’s perhaps more accurate to call him the king of the sci-fi genre. He’s made some of the biggest and most popular works of science fiction in cinematic history, with none being as successful (at least financially) as his 2009 film Avatar. Indeed, Avatar joins Titanic and its own sequel, Avatar: The Way of Water, as a movie that can claim to be the highest-grossing of its decade of release.

It recycles familiar tropes and story beats, but does so in a fantastical world and with breathtaking visual effects. Typical of Cameron, Avatar is also successful in blending genres to ensure it has mass appeal, with this movie being a sci-fi film, an action/adventure movie, and a romance all at once.

32 ‘Planet of the Apes’ (1968)

Directed by Franklin J. Schaffner

For as good as the reboot/prequel trilogy released throughout the 2010s was, it’s hard to top the original Planet of the Apes film from 1968, at least when judging each movie in the series on its own merits. It’s an eerie and oftentimes mysterious film, building to a fantastic conclusion that might still surprise those lucky enough to avoid knowing about it without having seen the movie.

It flips things around by having human beings be the subservient species, and forced to contend with an advanced race of apes who do indeed rule the planet they’re on. It’s not nearly as cheesy as you’d think (the sequels don’t fare quite so well), and holds up as a compelling and entertaining sci-fi/action movie with some interesting things to say about humanity and its possible future.

Watch on Starz

31 ‘District 9’ (2009)

Directed by Neill Blomkamp

Though some are clamoring for a sequel that will probably never arrive (never say never, unless you can cowardly include a “probably” in there), District 9 still stands on its own as a great film regardless. It’s part mockumentary, part action movie, and part body horror, detailing what happens to an alien ship that becomes stranded over the city of Johannesburg.

It’s also packed with social commentary regarding race and how refugees are mistreated in real life, considering in this movie, it’s the aliens who find themselves in the middle of a large-scale refugee crisis. It’s thought-provoking, unique, exciting, and one of the best science-fiction movies of the 21st century so far, as well as one movie that demonstrated how 2009 was an unusually good year for the sci-fi genre as a whole.

30 ‘Stalker’ (1979)

Directed by Andrei Tarkovsky

One of the most acclaimed films of 1979, Stalker is also among the best-known titles in Andrei Tarkovsky‘s filmography. It follows three men who are trying to find a mysterious location known only as the Zone, as it’s rumored to grant great power to anyone who can locate it. Stalker feels less focused on the narrative necessarily, as its status as an arthouse science fiction movie means it’s more concerned with exploring abstract themes and providing a unique (in this case, also eerie) mood.

It unfolds in a way that’s very slow, but also surprisingly absorbing. It’s an intensely psychological sort of science fiction, exploring the minds of its characters more so than putting them in a series of exciting set pieces or action scenes. It’s the kind of approach to sci-fi that might not be for everyone, but it is undoubtedly interesting.

29 ‘Moon’ (2009)

Directed by Duncan Jones

One of many great science-fiction movies released in 2009, Moon is about one man dealing with isolation while being the sole person at a manufacturing facility on the Moon. Things take a turn into the unexpected as he’s about to return to Earth, though, throwing the film’s events into an entirely new direction.

The less said about the rest of Moon, the better, but it’s fair to say that it’s certainly engaging and surprising in all the best ways. It’s also a showcase for the talents of Sam Rockwell, given he maintains a compelling presence on-screen, even though he doesn’t really have any other actual actors to appear alongside, and act with, and Moon undoubtedly solidifies Rockwell as one of the best and most underrated actors working today.

28 ‘Ex Machina’ (2014)

Directed by Alex Garland

Before taking a turn into horror by directing movies like Annihilation and Men, Alex Garland had his directorial debut with the sci-fi film Ex Machina. It’s a unique look at artificial intelligence, revolving around a series of experiments in a remote location with a new, unnervingly smart robot, the creator of said technology, and a young coder who’s won a competition to visit said location.

It’s an eerie and engaging look at familiar science-fiction tropes and ideas, presenting things that viewers might have seen before in ways that are confined, realistic, and eye-opening. It’s small-scale, personal science-fiction done right, and though it’s not particularly old, it feels like the kind of movie where it’s safe to say it will age well, and continue to hold up in years to come.

27 ‘Minority Report’ (2002)

Directed by Steven Spielberg

Minority Report is set in a future where surveillance has become so widespread and powerful that the crime/justice landscape has completely changed. Violent crimes can now be predicted before they even happen, leading to people being arrested and charged for crimes they didn’t actually commit, but were ultimately going to commit, or so those in the business of “Precrime” say.

It’s an uneasy and thought-provoking premise, and was explored in a way that ensured Minority Report ranked among the best movies of 2002. It’s getting on in years, but what it has to say still feels relevant and unnerving, and time will ultimately tell how relevant it’ll continue to feel, and how unsettling its premise will feel for viewers even further in the future. Undoubtedly, it’s one of the very best sci-fi/thriller movies Steven Spielberg has ever directed.

26 ‘Interstellar’ (2014)

Directed by Christopher Nolan

While Interstellar isn’t Christopher Nolan’s only great science-fiction movie, it might be his most pure sci-fi effort, given Inception‘s action-heavy nature and Tenet feeling like an espionage thriller with sci-fi elements. Interstellar‘s also one of his longest movies, making it a true sci-fi epic in every sense of the word.

It centers on a group of astronauts who explore space through a wormhole, as humanity is in danger on Earth and may need to find a new planet to live on. On the technical side of things, Interstellar is spectacular, with amazing visual effects and a phenomenal Hans Zimmer score. It’s a long but rewarding film, and in contrast to some science-fiction, also contains a surprising amount of heartfelt – maybe even sentimental – emotion.
