Netflix’s ever-expanding universe of original content has not only redefined the streaming landscape but also set a new standard for sci-fi storytelling. From mind-bending time travel dramas to dystopian thrillers and philosophical anthologies, the platform’s catalog is a testament to the creative risks and global scope that have become its trademark. Now, with the conclusion of one of its most talked-about series, Squid Game, and whispers of a potential American spinoff, Netflix’s sci-fi and action-mystery slate is once again at the center of pop culture conversation.
Few streaming platforms can boast the breadth and ambition of Netflix’s original sci-fi series. According to Collider, shows like Dark, Altered Carbon, Alice in Borderland, and 3 Body Problem have not only pushed the boundaries of visual storytelling but also delved deep into themes of technology, philosophy, and the human condition. These series often rely on intricate scripts and strong character arcs, weaving together narratives that are as intellectually stimulating as they are visually stunning.
Take Dark (2017-2020), for example. This German series is lauded as both critically acclaimed and criminally underrated. Set in the small town of Winden, the show unravels a multi-generational saga of time travel, exploring whether families can break free from the cycles that bind them. Its nonlinear plot and fairy tale-esque setting create an atmosphere that is both haunting and compelling. The success of Dark even inspired thematic echoes in later Netflix originals, such as 1899.
Equally ambitious is Altered Carbon (2018-2020), a cyberpunk odyssey set in a distant future where consciousness can be transferred between bodies, or "sleeves." The series follows Takeshi Kovacs, a former soldier tasked with solving his own murder centuries after his death. With a staggering $7 million budget per episode, Altered Carbon stands as one of Netflix’s most expensive productions, rivaling cinematic blockbusters like Blade Runner in its world-building and visual effects.
Netflix’s international reach is further exemplified by Alice in Borderland (2020-Present), a Japanese thriller that throws its characters into an alternate, game-driven Tokyo. Much like Squid Game, survival hinges on completing deadly challenges, with the mysterious game of Ddakji playing a central role. The show’s use of playing cards as life-or-death tokens adds a layer of suspense and strategy, keeping viewers guessing until the very end.
On the animation front, Love, Death, and Robots (2019-Present) stands out as a bold anthology series that explores a range of sci-fi concepts through diverse styles and tones. Episodes like "Bad Traveling" and "Zima Blue" showcase the series’ willingness to experiment, collaborating with animators around the world to bring unique perspectives to the screen. As Collider notes, this adult animation pushes the boundaries of what’s possible in the medium, tackling mature themes with creativity and depth.
But perhaps no Netflix series has captured global attention quite like Squid Game. Created by Hwang Dong-hyuk and running from 2021 to 2025, the action-mystery phenomenon quickly became a cultural touchstone. The show’s harrowing depiction of survival games, layered social commentary, and unforgettable characters earned it an 86% critic score on Rotten Tomatoes, though audience scores were somewhat more divided at 66%. According to Screen Rant, the series’ finale—aired before September 20, 2025—delivered a satisfying conclusion while leaving the door open for future stories.
The final moments of Squid Game sparked a frenzy of speculation. In a move that stunned both fans and critics, Oscar-winning actress Cate Blanchett appeared in a surprise cameo as a recruiter in Los Angeles. Her character was seen playing Ddakji, the same Korean game used to select players in the original series. This detail wasn’t lost on viewers; as Screen Rant points out, it suggests that the deadly game has spread worldwide, potentially setting up an international expansion of the franchise.
"The Ddakji could indicate that all the versions of the game across the world use Ddakji as a tribute to Il-nam, the creator, and the Korean origins of the game," Screen Rant explains. The appearance of Blanchett’s recruiter in America hints at a global network of games, raising tantalizing questions about how the show’s lore might evolve.
Rumors have swirled about the possibility of an American spinoff, though Netflix has yet to confirm any such project as of September 2025. Industry chatter has even linked acclaimed director David Fincher to the rumored series, given his previous collaborations with Netflix on projects like Mindhunter. While nothing is official, the prospect of Fincher helming a Squid Game spinoff—possibly with Blanchett reprising her role—has fans buzzing with anticipation.
For her part, Blanchett has expressed openness to returning for future Squid Game projects. As Screen Rant reports, "Blanchett has discussed the rumors of the American Squid Game spinoff, saying she's open to anything, and since Fincher is potentially attached, this could be good news as well." The show’s director, Hwang Dong-hyuk, has stated that he wanted a dramatic and impactful performer for the final cameo, believing that having a female recruiter would be the most compelling choice.
The original Squid Game may have wrapped up its core story, but the seeds of expansion have clearly been planted. As Screen Rant notes, "An American spinoff would be very different from the original Squid Game, but Blanchett's cameo indicates that there are games happening all over the world, and the use of Ddakji could indicate that they're all connected." Such a move would allow Netflix to explore new characters, settings, and cultural contexts, broadening the show’s already considerable appeal.
This approach is consistent with Netflix’s broader strategy for sci-fi and genre storytelling. Whether it’s the interconnected narratives of Sense8—created by the Wachowskis and praised for its authentic diversity—or the mythological depth of The OA, Netflix has shown a willingness to invest in ambitious, globally minded series. Even shows that ended prematurely, like Into the Night (which holds an 88% Rotten Tomatoes score despite its cancellation after two seasons), have left a lasting impression on audiences and critics alike.
As fans await official word on the future of Squid Game and other Netflix sci-fi properties, one thing is clear: the streaming giant’s commitment to experimental storytelling, international collaboration, and high production values continues to shape the genre for a new generation. With rumors swirling, cameos sparking debate, and creators hinting at even bigger worlds to come, Netflix’s sci-fi universe remains as unpredictable—and compelling—as ever.
For now, viewers can only speculate about what’s next. But if history is any guide, Netflix isn’t done surprising us yet.
