5 min readSnowfall as Metaphor: How The Eternaut Turns Buenos Aires Into a Ghost of Itself
I’ve seen this trick before—the alien invasion disguised as something mundane. A snowstorm in summer. A quiet disaster that doesn’t announce itself with fireworks or spaceships, but with the creeping dread of something wrong.
Netflix’s The Eternaut pulls it off, though not without stumbling. The series, adapted from Héctor Germán Oesterheld and Francisco Solano López’s 1957 Argentine comic, is a slow-burn survival story where the real enemy isn’t the aliens, but the way fear turns neighbors into threats. And yet, for all its atmospheric tension, it’s the weight of history—not just the comic’s, but Argentina’s—that lingers like the toxic snow itself.
Bruno Stagnaro, the director, has spent his career training his lens on the margins of Argentine society—gritty crime dramas like Pizza, Birra, Faso and Okupas, where the city feels lived-in, even when it’s falling apart. Here, he turns that same eye to a Buenos Aires under siege, but the stakes are cosmic. The series opens with a snowfall that shouldn’t be possible, a white blanket that kills on contact.
Within hours, the city is a ghost town, its survivors huddled in apartments and subway tunnels, trying to make sense of what’s happening. The aliens, when they reveal themselves, are almost an afterthought. The real horror is the way the snow erases everything—buildings, bodies, the rules of how the world is supposed to work.
Stagnaro’s Buenos Aires is a character in its own right, a city of contradictions: grand European boulevards and crumbling tenements, the River Plate Stadium standing empty like a monument to a world that no longer exists. The series was shot on location, and it shows. The snow isn’t just CGI frosting; it’s a physical presence, clinging to the actors’ clothes, muffling their voices.
In one early scene, Juan Salvo (Ricardo Darín) steps into the street, his breath visible in the cold, and the camera lingers on the way the snow swallows the sound of his footsteps. It’s a small moment, but it’s the kind of detail that makes the apocalypse feel real.
The comic El Eternauta has always been more than just a sci-fi story. Oesterheld, its writer, was a leftist intellectual who disappeared during Argentina’s military dictatorship in the late 1970s, along with his four daughters. The comic, with its themes of resistance and collective survival, became a symbol of defiance.

Buzz & Rumors
Public reportsNetflix’s The Eternaut (2025): How a 70-Year-Old Comic Became Argentina’s Most Anticipated Sci-Fi Series
Bruno Stagnaro’s The Eternaut (2025) isn’t just another post-apocalyptic series—it’s a decades-in-the-making adaptation of one of Argentina’s most beloved comics. The Netflix original, starring Ricardo Darín, has finally brought Héctor Germán Oesterheld and Francisco Solano López’s 1957 graphic novel to life, but not without a fight. latestnetflix.com's read is that here’s what we know about the making of this long-awaited project.
A Comic That Almost Never Got Its Screen Moment
The Eternaut’s journey to the screen was anything but smooth. The comic, a Cold War-era allegory about an alien invasion disguised as a toxic snowfall, has been a cultural touchstone in Argentina since its debut. But adapting it proved difficult. The Oesterheld family, which holds the rights, reportedly rejected multiple offers over the years, insisting any adaptation stay true to the story’s Spanish-language roots and Buenos Aires setting 
.
Netflix and creator Bruno Stagnaro finally won the family’s approval, but only after agreeing to strict conditions: the series had to be produced in Argentina, shot in Spanish, and remain faithful to the comic’s political undertones. Stagnaro, known for his work on Okupas and El marginal, was tapped to helm the project, bringing a gritty, character-driven approach to the sci-fi genre .
Ricardo Darín on Why This Story Still Matters
Argentina’s most famous actor, Ricardo Darín (The Secret in Their Eyes), takes on the role of Juan Salvo, the comic’s protagonist. In interviews, Darín has framed The Eternaut as more than just a survival story—it’s a reflection on resistance and tyranny. "Survival through teamwork: It’s a tale as old as time with particular resonance today," he told France 24, hinting at the series’ parallels to modern political struggles .
Darín’s involvement was a major coup for the project, but it also raised the stakes. The actor is notoriously selective about his roles, and his decision to lead The Eternaut signaled its importance. The series updates the original’s 1950s setting to the present day, incorporating cellphones and contemporary Buenos Aires while preserving the comic’s core themes of isolation and defiance .
Behind the Scenes: A Slow-Burn, High-Stakes Production
Stagnaro’s vision for The Eternaut was deliberate. Reviews describe the series as a "slow-burn" post-apocalyptic drama, focusing on the psychological toll of the invasion rather than nonstop action . This approach aligns with the comic’s tone, which Oesterheld originally used to critique authoritarianism under the guise of sci-fi.
The cast includes a mix of veteran Argentine actors and rising stars:
- Carla Peterson (El marginal) as Elena, a key survivor.
- César Troncoso (The Clan) as Favalli, a scientist fighting to understand the alien threat.
- Andrea Pietra and Marcelo Subiotto, both known for their work in Argentine cinema and TV
.
Production details are scarce, but the series was filmed in Buenos Aires, leveraging the city’s urban landscape to ground the story in reality. Rumors suggest Netflix pushed for a second season, but as of now, nothing has been confirmed.
Why This Adaptation Finally Worked
The Eternaut’s success hinges on its respect for the source material. Unlike many comic adaptations that prioritize spectacle over substance, Stagnaro’s series stays true to Oesterheld’s vision—even expanding on characters and relationships that the original comic only hinted at . The result is a haunting, character-driven thriller that feels both timeless and urgently modern.
For fans of the comic, the series is a long-overdue victory. For everyone else, it’s a reminder that some stories are worth the wait.
