Sci-fi and thrillers have always been a natural combination. There’s something inherently uncanny and tense about ideas of futuristic technology, space travel, or unknown life forms. Indeed, the subgenre’s best movies mine all these elements for maximum tension, resulting in truly shocking and anxiety-inducing masterworks.
With that in mind, this list looks at some of the iconic and timeless sci-fi thrillers that are great from beginning to end. Every tension-filled scene pushes the story forward, and there’s never a wrong note. The titles below are perfectly constructed and cleverly executed, sustaining the suspense the whole way through.
‘Contagion’ (2011)

“There’s informed discussion on the blogosphere that this is a biological weapon.” One of the smartest and most realistic “plague” movies ever. In Contagion, a mysterious illness spreads with terrifying speed across the globe. We follow doctors, scientists, government officials, journalists, and ordinary citizens as they struggle to understand and contain the pandemic before it wipes out civilization.
Director Steven Soderbergh (a storyteller with amazing range) builds suspense through procedural detail, focusing on the mechanics of tracing infections and developing vaccines. Obviously, it all rings uncomfortably true now in the wake of COVID, and it’s a big part of why Contagion is so good. It was remarkably prescient, while remaining thrilling rather than dry. It helps that the ensemble cast is so great: Matt Damon, Kate Winslet, Laurence Fishburne, Marion Cotillard, and Jude Law all turn in great work here.
‘A Scanner Darkly’ (2006)

“What does a scanner see?” Like Soderbergh, Richard Linklater has a varied filmography, including experimental dramas alongside blockbuster comedies. His strangest project, however, is this Philip K. Dick adaptation told through rotoscope animation. Set in a near-future America ravaged by addiction to the mysterious Substance D, A Scanner Darkly centers on undercover narcotics agent Bob Arctor (Keanu Reeves), who gradually loses his grip on reality while investigating the very drug to which he himself has become addicted.
The movie strikes a fine balance between dark humor, outright tragedy, and sci-fi speculation, while also nailing the author’s profound distrust of authority. Surprisingly, the dreamlike animation ends up suiting the subject matter perfectly. Rather than just being a gimmick, the constantly shifting visuals reflect Arctor’s deteriorating mental state, making it increasingly difficult for the audience to distinguish reality from hallucination.
‘Moon’ (2009)

“I want to go home.” Sam Rockwell leads this one as Sam Bell, a solitary worker nearing the end of a three-year assignment overseeing an automated helium-3 mining operation on the Moon. With only the station’s artificial intelligence, GERTY, for company, Sam eagerly anticipates returning home to his wife and daughter. However, after a serious accident outside the base, he uncovers a truth that forces him to question everything he believes about his identity.
This premise could’ve turned into a pulpy space thriller, but director Duncan Jones turns it into something a lot more interesting, in part thanks to his restraint. He avoids unnecessary action sequences or elaborate visual effects, instead leaning into psychological uncertainty. The genre elements never overwhelm the story’s human core, and Rockwell’s performance, lonely, confused, likable, and vulnerable, carries the whole thing.
‘Children of Men’ (2006)
