Netflix’s hit Argentine sci-fi thriller The Eternaut has officially been renewed for a second and final season, solidifying its place as one of the most talked-about international releases of 2025. Based on the legendary graphic novel by Héctor Germán Oesterheld and Francisco Solano López, the show debuted on April 30, 2025, and quickly surged into Netflix’s global Top 10.
With a 93% critic score and an overwhelming 97% audience rating on Rotten Tomatoes, its renewal came as little surprise—but the decision to wrap things up in Season 2 adds a layer of urgency and excitement to what comes next.
A Bold Post-Apocalyptic Tale That Resonates Worldwide
The series, known in Spanish as El Eternauta, blends classic sci-fi elements with political allegory, survival horror, and emotional depth. Its premise—a mysterious deadly snowfall blankets Buenos Aires as alien forces close in—has struck a chord with both longtime fans of the comic and newcomers unfamiliar with its historical roots. The original 1957-1959 comic series is considered a cornerstone of Argentine literature, widely praised for its commentary on authoritarianism and collective resistance. Netflix’s adaptation not only modernized the setting but deepened the emotional weight through stunning visuals and a character-driven narrative.
What to Expect in Season 2
Season 2 will feature eight episodes, expanding on the six-episode first season. According to Netflix Latin America’s VP Francisco “Paco” Ramos, the final chapter will “dig deeper into the mythology” of The Eternaut, promising more intense sci-fi concepts like alien telepathy, time travel, and humanity’s struggle for autonomy. Expect more philosophical undertones, as the characters grapple with freedom, memory, and fate—all central themes from the original work.
Producer Matías Mosteirin confirmed that Season 2 will be the definitive end of the story. The creative team aims to honor the spirit and structure of Oesterheld’s graphic novel, including a deeper exploration of the enigmatic “ellos” (the alien overlords) and the layered resistance movement fighting back against impossible odds.
Release Timeline: When Will Season 2 Arrive?
While no exact release date has been confirmed, Netflix insiders suggest a late 2026 or early 2027 launch. Season 1 reportedly took 18 months of post-production, largely due to its extensive use of CGI for the deadly snowfall, alien entities, and large-scale set pieces. Assuming a similar timeline, fans will likely see a trailer drop in late 2026, followed by a full release shortly after.
| Season | Episodes | Production Status | Expected Release Window |
|---|---|---|---|
| Season 1 | 6 | Released April 30, 2025 | Available now |
| Season 2 | 8 | In development (confirmed) | Late 2026 |
Who’s Coming Back
The core cast will return for the final season, led by celebrated actor Ricardo Darín as Juan Salvo, the everyman-turned-reluctant-hero navigating the surreal apocalypse. Also expected to return are:
- Carla Peterson as Elena
- César Troncoso
- Andrea Pietra
- Mora Fisz
Director Bruno Stagnaro will continue to helm the project, ensuring visual continuity and tonal consistency from the first season.
Why It Matters: More Than Just Sci-Fi
The Eternaut is more than a gripping thriller—it’s a cultural milestone. The original comic’s creator, Héctor Germán Oesterheld, was tragically disappeared by Argentina’s military dictatorship in 1977, and the work has since become symbolic of resistance, memory, and artistic courage. Netflix’s faithful adaptation not only honors the comic’s narrative but also its political legacy.
For viewers who appreciate layered storytelling, The Eternaut isn’t just another end-of-the-world drama—it’s a haunting reminder of how ordinary people can rise to meet extraordinary challenges. With Season 2 on the horizon, it’s clear that Netflix intends to close this story with the gravity and grandeur it deserves.

Storyline and Adaptation: What to Expect in Season 2
The second season of “The Eternaut” will build upon the foundation laid in season one while expanding on several key sci-fi concepts only hinted at previously. The renewal came just days after the first season premiered on Netflix.
Continuing the Tale of Juan Salvo
The upcoming season will follow Juan Salvo’s journey as he navigates the post-apocalyptic landscape. Netflix has confirmed the renewal with plans to conclude the story in the second season. Producer Matías Mosteirin indicated that many sci-fi concepts merely touched upon in the first season will be “fully blown” in the continuation.
The narrative will likely delve deeper into Juan’s search for his family while contending with the mysterious forces behind the alien invasion. His character development remains central to the storyline as he transforms from an ordinary man into “The Eternaut.”
Season 2 will consist of approximately eight episodes, providing enough time to wrap up the storyline in what producers call “a beautiful way.”
The Alien Invasion and Survival Themes
The toxic snowfall that initiated the catastrophe in season one will continue to play a crucial role in the follow-up season. This mysterious precipitation served as the aliens’ first attack against humanity, making outdoors survival nearly impossible.
Season 2 will likely expand on the invasion’s true purpose and the hierarchy of the alien forces. The “Them” – the shadowy entities controlling the invasion – may receive more screen time and backstory.
Survival themes will intensify as resources grow scarcer. The show will continue examining how ordinary people respond to extraordinary circumstances through its core characters. The sci-fi element will be amplified, with the production team planning to explore concepts only hinted at in the first season.
Adaptation of the Graphic Novel
Season 2 will continue adapting the original graphic novel created by writer Héctor Germán Oesterheld and artist Francisco Solano López. The creative team has indicated they feel the story can be properly told within a two-season framework.
“We can sustain it for a second season, but no more than that,” producer Mosteirin explained. “We feel that, artistically, that is the cycle to complete the story.”
The adaptation will likely incorporate more elements from the source material that weren’t included in season one due to time constraints. Fans of the original graphic novel might see some of their favorite moments from the later parts of the story finally brought to screen.
Clara, Survivors, and New Challenges
Juan’s search for Clara will remain a driving force in the narrative. Their separation is fundamental to the original story, and the second season will explore how this separation affects both characters.
The surviving group members will face new challenges as they navigate both the alien-controlled landscape and internal conflicts. Character dynamics established in season one will evolve as trust is tested and alliances shift.
According to Tom’s Guide, the second season will bring resolution to the survivors’ stories. The production team is confident they can conclude all major character arcs satisfactorily within the eight-episode framework.
New threats beyond the alien invaders may emerge, testing the survivors in ways they haven’t experienced before.
Key Elements and Iconic Imagery in The Eternaut
The Eternaut captivates viewers with distinctive visual elements that bring its post-apocalyptic world to life. These iconic images help tell the story of endurance and survival in the face of an otherworldly threat.
The Role of Buenos Aires and Setting
Buenos Aires serves as more than just a backdrop in The Eternaut—it becomes a character in its own right. The Argentine capital’s familiar streets and landmarks transform into an eerie wasteland as the story unfolds.
The show meticulously recreates the city’s architecture and neighborhoods, providing a realistic setting that makes the extraordinary events feel more immediate and threatening. Many scenes feature recognizable locations now abandoned or transformed by catastrophe.
Buenos Aires’ dense urban environment also creates natural barriers and safe zones that characters must navigate. The contrast between the city’s vibrant pre-disaster life and its snow-covered, silent streets emphasizes the devastating impact of the alien threat.
The state and military presence throughout the city adds another layer to the setting, with government buildings and military installations becoming crucial plot points.
Mysterious Snowfall and Alien Threat
The toxic snowfall serves as the most memorable visual element in The Eternaut. What begins as a seemingly beautiful weather phenomenon quickly reveals itself as something deadly and unnatural.
Key characteristics of the toxic snow:
- Glowing appearance: Often depicted with an otherworldly luminescence
- Instant death: Kills most living things on contact
- Persistence: Continues falling throughout much of the story
The dangerous snowfall and creeping terror gradually reveals the true alien threat behind it. The show portrays this invasion through increasingly disturbing imagery.
The snow serves as both weapon and warning, a visual representation of how normal life can be instantly transformed by forces beyond human understanding.
Gas Masks, Waterproof Clothing, and Survival Gear
The improvised protective equipment worn by survivors becomes one of the most iconic visual elements of The Eternaut. These items transform from everyday objects into life-saving technology.
Gas masks become particularly symbolic, representing both protection and the dehumanizing effect of the disaster. Characters must remain completely covered to survive, with their faces hidden behind these unsettling devices.
Waterproof clothing like:
- Plastic raincoats
- Sealed gloves
- Boots
- Homemade suits
All these items create a distinctive visual silhouette for the survivors. The contrast between ordinary household items repurposed as survival gear highlights the show’s themes of human ingenuity and adaptation.
This equipment also serves as a visual reminder of the constant danger in this post-apocalyptic tale where even the air itself can be deadly.
Cast, Creative Team, and Broader Impact
The renewal of “The Eternaut” for a second season brings back the talented team that made the first season a success. The show has quickly built a strong reputation, earning a 92% score on Rotten Tomatoes.
Ricardo Darín and Principal Cast
Ricardo Darín leads the cast with his compelling performance in this adaptation of the iconic Argentine comic. His portrayal brings depth to the post-apocalyptic narrative that has resonated with viewers worldwide.
The show features a primarily Argentine cast, honoring the story’s roots while bringing fresh interpretations to these beloved characters. Netflix’s investment in Latin American talent shows in the quality of performances throughout the series.
The casting choices reflect a commitment to authenticity, with actors who understand the cultural significance of “El Eternauta” in Argentine literature and history. This attention to detail has helped the series connect with both new audiences and long-time fans of the original comic.
Direction by Bruno Stagnaro
Bruno Stagnaro will return to direct the second season, maintaining creative continuity for the show. His vision for the contemporary adaptation has successfully translated the comic’s themes to modern audiences.
Stagnaro’s direction balances sci-fi elements with human drama, creating a show that works on multiple levels. His collaboration with the production team has resulted in striking visuals that capture the eerie atmosphere of the snow-covered apocalypse.
Producer Mosteirin has indicated that the show was conceived with a specific narrative arc in mind, stating that “We can sustain it for a second season, but no more than that”. This suggests a thoughtful approach to storytelling rather than an open-ended series.
Legacy of El Eternauta in Popular Culture
“El Eternauta” holds a special place in Argentine culture as more than just a comic book. The original work by Héctor Germán Oesterheld has become a significant cultural touchstone that combines science fiction with political allegory.
Netflix’s adaptation honors this legacy while introducing the story to global audiences. The streaming platform’s commitment to the project demonstrates the universal appeal of the narrative despite its specifically Argentine origins.
The show’s success has sparked renewed interest in the original comic, published in the late 1950s. The themes of resistance against invasion and collective action remain relevant today, which partly explains why the series has been quickly renewed just days after its premiere.
The term “eternaut” itself refers to a “time traveler”, fitting for a story that continues to resonate across generations and now finds new life on Netflix.
