13 Best Science Fiction Movies On Tubi

Staff & contributors

Aside from their high entertaintment value, speculative tales take us on imaginative journeys while also challenging us to reflect on the world. Whether you’re into extraterrestrial life or time travel, here are the best sci-fi and fantasy movies to stream.

Named for all the connections that form a functioning society, Threads is a harrowing look at what might happen when those ties are rent apart by nuclear war. This British TV movie — released during the Cold War — so violently seized on the nuclear anxieties of the time that its premiere was dubbed “the night the country didn’t sleep.” Depressingly, it hasn’t lost that initial resonance, and so it remains a panic attack-inducing watch.

Threads begins in the kitchen-sink vein of a Ken Loach movie. In the northern industrial town of Sheffield, a young couple from different social classes (Reece Dinsdale and Karen Meagher) discover they’re about to be parents — but looming above their small-scale drama are the clouds of war, as televisions and radios blare out the details of escalating tensions between the US and the USSR. And then, it happens: the town is strategically bombed, and Threads unfurls into an unrelenting nightmare. In the documentary-like approach that follows, it spares no graphic or emotional detail, charting both the personal devastation caused by the bomb and the annihilating impact of the nuclear holocaust on all the vital infrastructure we take for granted. In short, one of the bleakest, most terrifying movies ever made.

Before anything else, Miracle Mile is a romance. It begins with a meet-cute so adorable, it convinces lovebirds Harry and Julie to stick to each other in the next moments of the film, which couldn’t be more different than the first. Where the opening scene is sweet and lovely, the ones that follow it are fraught and bleak and eerily existential. At this point, the film transforms into its true self: an apocalyptic nightmare. When Harry receives word that a nuclear attack is incoming, the news spreads like wildfire and all hell breaks loose in this film that makes you question reality and humanity. 

It's one of the smoothest shifts in cinematic history, but even with panic swirling and violence erupting, love is still there. Harry and Julie’s quest to save and savor the bond they’ve formed is genuinely moving, and it effectively grounds this out-of-this-world film about the end.

A zombie virus breaks out and catches up with a father as he is taking his daughter from Seoul to Busan, South Korea’s second-largest city. Watch them trying to survive to reach their destination, a purported safe zone.

The acting is spot-on; the set pieces are particularly well choreographed. You’ll care about the characters. You’ll feel for the father as he struggles to keep his humanity in the bleakest of scenarios.

It’s a refreshingly thrilling disaster movie, a perfect specimen of the genre.

The movie starts with Professor John Oldman packing his things to leave and start a new life. He invites his friends to say goodbye and decides to reveal the reason for his departure. The starting point of the narration is a simple question asked by Oldman to his friends: what would a man from the upper paleolithic look like if he had survived until the present day? As scientists, the protagonists play his game and investigate the question, not knowing whether the story is a bad joke or a genuine narration. One of the best movies I've watched and definitely one of the most under-rated.

Genre: Drama, Science Fiction

Actor: Alexis Thorpe, Annika Peterson, David Lee Smith, Ellen Crawford, John Billingsley, Richard Riehle, Robbie Bryan, Tony Todd, William Katt

Snowpiercer is an under-the-rader post-apocalyptic thriller that offers the grittiness that many times only Asian cinema may achieve. South Korean director Joon-ho Bong forces audiences to forget that Chris Evans was ever a Marvel superhero, as he leads a revolt of his fellow “low-class” citizens against the self-appointed gentry in a train that contains all remaining members of the planet. With immersive environments and a layered script, this film melds together social commentary and moral discourse in a visually arresting and vastly entertaining package.

Genre: Action, Drama, Mystery, Science Fiction

Director Wong Kar-Wai made this loose sequel to one of the best films ever made, his 2000 classic In the Mood for Love. Much of the story is set around Christmas eve.

In the far future, people take a train to the world of 2046, where no sadness or sorrow can be experienced. No one has ever returned from that world except for a lonely Japanese writer, who narrates the first part of the film.

There are four acts to the story and as is common to Wong Kar-Wai, they are listed in non-chronological order. Not that you will care but 2046 is far from confusing. Instead, it functions as a dazzling visual poem on unreciprocated love.

Genre: Drama, Fantasy, Romance, Science Fiction

Taking the Frankenstein story to its low-budget '80s extremes, Re-Animator finds lots of dry humor and gory thrills in the simple story of a mad scientist in medical school. But instead of any Frankenstein's monster terrorizing the university, it's the hubris of man and their arrogance in denying the inevitability of death that constantly threatens every other innocent person in the film. The scare to minute ratio here is refreshingly low, meaning Re-Animator isn't driven by a need to manipulate audiences, but by the primal thrills of fake guts and blood—and a sharp, snarky performance from Jeffrey Combs.

Genre: Comedy, Drama, Horror, Science Fiction

Actor: Al Berry, Barbara Crampton, Bruce Abbott, Bunny Summers, Carolyn Purdy-Gordon, David Gale, Gene Scherer, Gerry Black, Ian Patrick Williams, Jeffrey Combs, Peter Kent, Robert Sampson

Coherence is a film that captivates you to the point of questioning the reality that surrounds you. It's a Quantum physics based sci-fi thriller that keeps your eyes sealed to the screen - not with unrealistically beautiful actors or special effects, but with an original screenplay and unexpected twists. Very refreshing.

The Witch hardly reinvents the thriller wheel. In fact, part of the fun in watching it is calling out the cliches. Cold-blooded villain? Check. Antihero who defies death? Check. Senseless, bloody killings for minutes on end? Check, check, check. The Witch has everything you'd expect from an action movie, and yet, the viewing experience is all the better for it. 

By trimming all the unnecessary fat and zeroing in on the action, director Park Hoon-jung delivers a no-nonsense, no-holds-barred film that could hold a candle to the John Wick franchise. Like those films, the movements here are sharp and the gore relentless. The only difference is that The Witch is led by a teenage girl—seemingly flimsy but deliciously deranged, Kim-Dami is magnetic in her breakout role as the titular witch Ja-yoon. It's also a bit like Stranger Things in that sense, but comparisons aside, The Witch stands out as a razor-edged entry into the genre.

Besides the futuristic tech that pops in and out, there’s not a lot about The Kitchen that signals it as a sci-fi film. Neglected housing projects and violent raids have become too common to count as dystopian, so it often feels like The Kitchen could’ve gone without labeling itself as part of the genre (the real world is bad enough). But underneath those layers is a subtle but sublimely tender story about father and son finding each other amid the rubble of real life. First-time directors Daniel Kaluuya (Get Out, The Black Panther) and Kibwe Tavares delicately balance the personal and the political, never undermining the former as many socially aware films do. If Kaluuya and Tavares had fleshed the world it built a little more and removed the parts, such as the sci-fi elements, that did not work out, then Izi and Benji’s story would have been memorably devastating, instead of just affecting.

A splendid animated movie by the legendary animator and director Satoshi Kon. A team of scientists and psychologists have created a device allowing them to enter someone else's dreams. Even if the usage of this device is not allowed outside of her facility, Doctor Atsuko Chiba is using it to cure patients from depression. Things start to get complicated when a stolen device is being used by someone to implement confusing dreams in various victims, causing them to mentally break down.

To be fair to this visibly low-budget adaptation of H. G. Wells' seminal science-fiction novel, it doesn't always settle for the cheap way out. Though it still leaves much to be desired in its visual effects, awkward action scenes, and generally unimaginative direction, Fear the Invisible Man makes a valiant effort to deepen its story by placing a strong, unlikely protagonist at its center (played in all seriousness and with admirable resolve by Mhairi Calvey). Since the titular villain isn't actually the star of the show—nor is he made out to be an ever-present threat, like in the modern 2020 adaptation—this version of The Invisible Man is able to circle relatively newer ideas about a woman's "invisible" place in the world, and how she's tempted to go down a path of pride and violence. If only the rest of the film could keep up with the script's ambition.

Genre: Horror, Science Fiction, Thriller

Filmmaking is a difficult thing. And there are countless filmmakers—the directors of this film included—who have strong ideas and just need the right time and support to have their vision realized. But there's no other way around it: Colonials was not ready to leave the pre-production phase, much less ready to be released on streaming. Non-existent production values, embarrassing visuals, unfinished sound design that leaves most of the actors muffled and unintelligible, incoherent world building, dumb action, and terrible performances—there really isn't anything worth checking out here. That the film has the gall to tease a potential sequel feels cruel.

Genre: Action, Science Fiction

Actor: Daniel Roebuck, Greg Kriek, Jamie Bernadette, Jon Provost, Louise Barnes, Mike Ferguson, Sean Kanan
