11 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.

In a world where mortality has been overcome, people watch in awe as the as the 118-year-old Nemo Nobody, the last mortal on Earth, nears his end. He is interviewed about his life, recounting it at three points in time: as a 9-year-old after his parents divorced, when he first fell in love at 15, and as an adult at 34. The three stories seemingly contradict each other. Utilizing non-linear cinematography, Belgian director Jaco Van Dormael presents each of these branching pathways as a version of what could have been. The result is a complex, entangled narrative. That and the movie's ensemble cast, featuring Jared Leto, Sarah Polley, and Diane Kruger, have turned Mr. Nobody into a cult classic. The soundtrack, featuring several of the beautifully restrained music by Eric Satie, is also considered a masterpiece. While it is surely not for everybody, this is trippy, intimate, and existential sci-fi at its best.

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.

In the year of the Netflix TV Show Maniac, another absurdist title stole critics’ hearts. Sorry to Bother You is a movie set in an alternate reality, where capitalism and greed are accentuated. Lakeith Stanfield (Atlanta) is a guy called Cassius who struggles to pay his bills. However, when at a tele-marketing job an old-timer tells him to use a “white voice”, he starts moving up the ranks of his bizarre society. A really smart movie that will be mostly enjoyed by those who watch it for its entertaining value, and not so much for its commentary. It is like a Black Mirror episode stretched into a movie.

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.

When categorizing Lars von Trier's oeuvre, critics speak of a "Depression Trilogy" bookended by Antichrist and Nymphomaniac, but Melancholia is the one that really embodies the concepts and worries nested at the heart of this project. The Danish director may be known for his provocative approach to filmmaking and disregard of taboos, but with this film, he makes room for vulnerability. On the character of Justine (Dunst) he places the weight of the world, only after allowing her to be weak, small, and socially unacceptable at her own wedding celebration. A rather subversive decision, but vesting these expectations in someone as wide-ranging as Kirsten Dunst assures an absolute win, even if there remain some questionable characteristics that align too well with abstract male fantasies of what a woman in distress would look like.

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.

Actor: Alex Manugian, Alexis Boozer Sterling, Aqueela Zoll, Elizabeth Gracen, Emily Baldoni, Hugo Armstrong, Kelly Donovan, Lauren Maher, Lorene Scafaria, Mark Ballou, Maury Sterling, Nicholas Brendon

A man accidentally gets into a time travel machine and travels one hour back in time. He finds himself stuck in a series of disasters of unforeseeable consequences, with unusual and thrilling moments at every corner. Similarly to Primer, this movie goes to prove that with intelligence and attention to detail, you don't need a big budget to create an unforgettable story. Great acting, great story-line, and a great thriller.

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.
