11 Best Sci-Fi Thrillers Movies to Watch

Staff & contributors
Ex Machina is the directorial debut of Alex Garland, the writer of 28 Days Later (and 28 Weeks Later). It tells the story of Caleb (Domhnall Gleeson from About Time), an IT developer who is invited by a billionaire CEO to participate in a groundbreaking experiment—administering a Turing test to a humanoid robot called Ava (Alicia Vikander). Meeting the robot with feelings of superiority at first, questions of trust and ethics soon collide with the protagonist's personal views. While this dazzling film does not rely on them, the visual effects and the overall look-feel of Ex Machina are absolutely stunning and were rightly picked for an Academy Award. They make Ex Machina feel just as casually futuristic as the equally stylish Her and, like Joaquin Phoenix, Gleeson aka Caleb must confront the feelings he develops towards a machine, despite his full awareness that 'she' is just that. This is possibly as close to Kubrick as anyone got in the 21st century. Ex Machina is clever, thrilling, and packed with engaging ideas.

This film really satisfied my craving for an original thriller, despite the fact that I spent most of it thinking about how Logan Marshall-Green looks like a budget Tom Hardy.

He plays a guy whose wife is killed during a violent mugging that also leaves him paralyzed in the aftermath. When a billionaire approaches him with an Artificial Intelligence solution that would "upgrade" his body, he has a chance to take vengeance.

This is Robocop meets Ex Machina meets Blade Runner. It's original, low-budget without feeling low-budget, and honestly just so thrilling. It gives the genre of sci-fi a much needed upgrade.

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.

A Cormac McCarthy novel adaptation (like No Country for Old Men), The Road is an apocalypse movie set in a 'scorched Earth' rendition of the world. It follows a father (played by Viggo Mortensen) and his son as they battle to survive everyday life. Throughout the movie, the son's trust in his father grows and shrinks depending on choices the father makes, as he attempts to protect his son from cannibals, bandits, and the threat of starvation. The gritty realism this movie presents sets it apart from many other more theatrical releases, with the setting of a charred world illustrating a rather depressing new reality. A very down to earth and heartfelt story. Definitely worth the watch if you're willing to feel like you've been punched in the gut.

When citizenship and rights can only be achieved through federal service, you have no choice but to militarize. Johnny Rico is young, impressionable, but noble; in other words, he is an archetypal hero even if he initially enlists just to be close to his girlfriend Carmen (Denise Richards). From then on, Starship Troopers unfolds as a high-strung high school drama, but in the middle of a space colonization. During one such mission, a highly evolved insectoid race, Arachnids, proves to be the most dangerous enemy to human supremacy and the fight is on. What's interesting about Starship Troopers is that it shows how a well-oiled propaganda machine works and for that reason, it was accused of indoctrination and army endorsement. Even more, it was dubbed fascist, instead of the fascist satire it claimed to be. But today, it's indisputably a cult film and a great introduction to the Paul Verhoeven's work in Hollywood.

Sunshine is a sci-fi thriller that details pretty much exactly what you don't want to happen on your journey into space. It follows the struggles of a crew who know that they are humanity's last hope to rekindle a dying sun and save their loved ones back home. Out of radio contact with Earth, relationships become strained and when things start to go horribly wrong the diverse cast give a fantastic performance as they encapsulate both the terror and humanity that arises from such an alien situation. Directed by Danny Boyle (Trainspotting, 28 Days Later).

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.

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.

This little gem of a sci-fi is based on actual physics theory and doesn't make you cringe every time some technobabble word comes out. Watching it the first time around leaves most viewers puzzled at the end, but wanting to see it again. Shot at a budget of ~$7000, don't expect any flashy special effects or CGI. Do be prepared, however, for some mind boggling paradoxical ideas that require some effort to wrap your brain around.
