6 Sci-Fi Thrillers You’ll Think About for Weeks

Science fiction is a remarkably flexible genre, thriving in many different forms of media. It’s enjoyable on its own, but also blends well with other genres like horror, action, and thrillers. A specific type, called “Hard Sci-fi,” focuses on realistic and scientifically plausible concepts.

Science fiction thrillers have become incredibly popular and highly praised over time. However, certain films truly stand out as the best examples of the genre, offering a genuinely chilling experience. These movies don’t just entertain; they can leave a lasting impression, leaving viewers speechless and amazed long after the credits roll.

The Long Walk Hits a Little Too Close to Home

Released in 2025, The Long Walk is the newest movie on this list and one of several Stephen King stories adapted for the screen this year. Other King projects that came out in 2025 include The Monkey, The Running Man, and the first season of HBO’s IT: Welcome to Derry. While all of these adaptations are well-made, The Long Walk has particularly impressed both critics and audiences.

The movie is set in a bleak 1970s, following a devastating war that left the country in deep poverty. To escape the hardships of everyday life, young men across the nation compete in a televised event called The Long Walk. The rules are straightforward: one contestant from each state walks alongside 49 others, maintaining a constant pace of 3 miles per hour – and they can’t stop, ever.

In this competition, the last person remaining wins. The prize isn’t just a significant amount of money – which is the main attraction of The Long Walk – but also the chance to have any wish granted, no matter how outlandish. The film offers powerful commentary on difficult themes like poverty, financial hardship, war, and the impact of military rule. While all of these elements make the film memorable, it’s the wish itself that will truly stay with viewers long after the credits roll.

Contagion is a Scientifically Accurate Portrayal of a Pandemic

The 2011 film Contagion centers around a dangerous, fast-spreading virus transmitted through coughing and by touching contaminated surfaces. Upon its release, the movie was highly regarded by doctors and scientists for its realistic portrayal of a pandemic. Beyond the accuracy of its science, the film also boasts a strong cast and a gripping storyline.

What really struck me about the movie was how realistic it felt – it actually made it more terrifying! I learned that the filmmakers did a ton of research, drawing heavily from actual outbreaks like SARS in the early 2000s and the 2009 flu pandemic. Knowing that it was based on real events definitely added to the impact.

The movie Contagion was already good when it was released, but it feels even more impactful now, in 2025. After the COVID-19 pandemic brought the world to a standstill in 2020, people are much more aware of illness and how easily it spreads. Having all lived through a major pandemic that the world hasn’t fully moved past, Contagion is a film that really stays with viewers long after they’ve finished watching it.

District 9 Also Takes Inspiration From Real Life

The 2009 science fiction film, District 9, centers around an alien spaceship that arrives near South Africa. The government establishes a camp called District 9 to confine the aliens. The film draws heavily from the history of District Six in Cape Town, South Africa.

I really love how District 9 starts – it feels so real, like you’re watching a documentary. But it’s not just a documentary style; they blend that with traditional filmmaking as we follow this guy who’s slowly becoming one of the alien prawns, desperately searching for a cure. What’s clever is they keep that documentary feel going throughout the movie, using things like news reports, shaky cam footage, security camera clips, and even interviews with the characters. It’s a really effective way to build up the world and make everything feel believable.

District 9 tackles difficult and relevant issues like prejudice against strangers and the separation of people into different groups. It also asks big questions about what it truly means to be human and how we treat each other. The film uses the story of alien refugees to represent groups who are often mistreated, making these tough topics more accessible. This approach aims to make viewers think about similar injustices that happen in the real world, ultimately making the film more impactful and thought-provoking.

Inception Reimagines What a Heist Movie Can Be

The 2010 film Inception appears to be a simple heist movie at first glance. However, instead of stealing objects, the story centers around a team of skilled thieves who break into people’s dreams to steal valuable information. They don’t rob banks – they extract secrets from the minds of their targets while they sleep.

The movie Inception is famously complicated, and many viewers find it helps to watch it more than once to fully grasp the story. It’s a very imaginative film about a technology that allows people to enter and explore others’ dreams, and how that can blur the line between what’s real and what isn’t. The characters, who are skilled thieves, have to be ready for anything while also staying focused to avoid getting lost in the dream world.

Despite its dazzling visuals and complex plot, Inception is a surprisingly emotional film. It features a truly heartbreaking twist, and its ending remains open to interpretation, sparking debate among fans much like the ending of John Carpenter’s The Thing (1982).

They Live is an Underrated John Carpenter Sci-Fi Gem

John Carpenter is famous for classic horror films like The Thing and the original Halloween (1978). While often overlooked compared to those hits, his 1988 film They Live is considered by many to be one of his strongest works. The movie centers on a wanderer who discovers a disturbing reality thanks to a peculiar pair of glasses that reveal the truth hidden beneath the surface.

Nada, a wanderer, uncovers a shocking truth: the people in power aren’t human, but aliens cleverly disguised. These aliens are secretly controlling everyone else through hidden messages. Director John Carpenter has said the film was inspired by his frustration with President Reagan’s policies and the growing influence of money in politics and entertainment.

When They Live first came out, it wasn’t well-received by critics, who often criticized its social message and other aspects. However, over time, the film developed a large and dedicated fan base, and its story remains powerfully relevant today – perhaps even more so than when it was first released.

Ex Machina is a Chilling Tale With a Jaw-Dropping Ending

A24’s 2014 film, Ex Machina, is a remarkably realistic and unsettling science fiction story. It’s frequently cited by fans as a standout in the genre. The film centers around Caleb, a programmer chosen by his employer to conduct a Turing test – a method for evaluating artificial intelligence by seeing if a human can distinguish it from a real person through conversation.

Caleb starts to fall in love with Ava, a remarkably lifelike android who appears as a woman, as they spend time together. He becomes deeply concerned for her welfare, and Ava, capable of understanding and mimicking human emotions, uses his feelings to her advantage. She needs his help to escape her creator, who plans to take her apart and build a new, improved model.

Ex Machina is a thought-provoking film that explores what it truly means to be human. It asks whether a robot capable of understanding and experiencing emotions could be considered human, and conversely, if a deeply cruel person can still be considered one. Like other films of its kind, it’s a movie that stays with you long after the credits roll.
