The Eternaut (El Eternauta), first published in 1957 as a graphic novel in Argentina, is far more than just a science fiction tale—it’s a story layered with deep political and cultural significance. Written by Héctor Germán Oesterheld and illustrated by Francisco Solano López, the narrative follows a group of everyday people in Buenos Aires as they try to survive a mysterious and lethal snowfall, which marks the beginning of an alien invasion. While thrilling on the surface, the story also serves as a powerful metaphor for resistance, fear, and authoritarian control. As Argentina moved into a period of dictatorship and unrest in the 1960s and 1970s, Oesterheld’s work took on a more direct and daring tone, especially when he reimagined The Eternaut as a critique of totalitarian rule and foreign dominance. In a tragic twist of fate, his life began to reflect his art—Oesterheld became involved with the leftist Montoneros group and, in 1977, was abducted by the ruling military regime along with his four daughters. None of them were ever seen again. Over the decades, The Eternaut has come to represent much more than a cult sci-fi comic; it stands as a symbol of courage, dissent, and the resilience of creative voices in the face of censorship and oppression. The 2025 Netflix series honors this legacy, reintroducing the story with striking visuals and emotional depth, while also preserving its historical weight and tribute to those silenced during one of Argentina’s darkest chapters.

Cast & Characters

Ricardo Darín as Juan Salvo, the central figure who transforms from an everyday man into a reluctant hero.
Carla Peterson as Elena, bringing emotional balance to the story.
César Troncoso, Andrea Pietra, and Ariel Staltari round out the cast with strong supporting roles.

Darín’s performance stands out, delivering emotional depth and resilience. The cast effectively portrays the fear, tension, and humanity of a society on the edge.

Production Quality

The series is visually impressive, combining on-location shoots with cutting-edge virtual production. Filming took place in more than 35 locations across Buenos Aires, enhanced by over 25 digital stages. This creates an immersive, snow-covered wasteland that feels both haunting and authentic. The use of CGI is well-balanced, making the alien invasion feel realistic without overpowering the grounded tone of the show.

Themes & Impact

At its core, The Eternaut is about survival—not just against aliens, but against fear, isolation, and the collapse of social order. It touches on themes of unity, resistance, and the fragility of civilization when faced with the unknown. Fans of dystopian and survival stories will find familiar echoes of The Last of Us or Fallout, but with a uniquely Latin American voice and perspective.

The Netflix original series The Eternaut (El Eternauta) is set to debut worldwide on April 30, 2025.
