The Argentinian science fiction series O Eternauta has quickly captured the attention of audiences since its premiere on April 30, 2025. Based on the iconic comic by Héctor Germán Oesterheld and Francisco Solano López, the show has already made its way into the top 10 most-watched series on Netflix Brazil. The series unfolds in a post-apocalyptic Buenos Aires, where a mysterious and deadly snowstorm threatens the city and forces a group of survivors to confront both the elements and their fellow humans.
At the center of the narrative is Juan Salvo, portrayed by acclaimed actor Ricardo Darín, who leads a group of friends as they navigate the chaos of a city gripped by an unprecedented climate catastrophe. The story begins with a bizarre blizzard striking Buenos Aires in the summer, an event that soon reveals itself to be a deadly alien invasion. "The originality of O Eternauta is that things start happening in the south. It's a science fiction story set in Argentina, particularly in Buenos Aires," says César Troncoso, who plays Alfredo ‘Tano’ Favalli.
The series consists of six episodes, each intricately weaving themes of solidarity, resistance, and the moral dilemmas faced by the characters. As they struggle to survive, the group must also contend with the dangers posed by both an alien force and their fellow countrymen, who are equally desperate in their fight for survival. The tension is palpable as the characters grapple with their own humanity amidst the chaos.
One of the standout features of O Eternauta is its impressive special effects, which recreate a snowy, apocalyptic Buenos Aires. The production team employed a mixture of salt, foam, cellulose, and baby diaper gel to simulate snow, creating a unique visual experience. "It's complicated. You have no idea how slippery baby diaper gel is," recalls Carla Peterson, who plays Elena, Salvo's ex-wife. The series also showcases a massive wall of cars, known as the Muralha, that serves as a striking backdrop to the unfolding drama.
Directed by Bruno Stagnaro, O Eternauta is the first audiovisual adaptation of the beloved graphic novel, maintaining the spirit and vision of its creators while also introducing new elements. The show underwent two years of development, nearly five months of pre-production, and a year and a half of post-production, culminating in a total of 148 days of filming with a cast of 2,900 actors, both main and extras.
Fans of the original comic have noted that while the series adds layers of complexity, it also stays true to the source material's commentary on social issues and authoritarianism. The narrative is not just about survival; it also serves as a critique of power dynamics and societal structures. As the characters face their dire circumstances, viewers are prompted to reflect on broader themes of control, manipulation, and the resilience of the human spirit.
Netflix has confirmed that a second season of O Eternauta is already in the works, much to the delight of fans eager to delve deeper into the mysteries presented in the first season. With its compelling narrative and rich character development, the series promises to continue exploring the complexities of human relationships in the face of disaster.
As the story unfolds, the audience is drawn into a world where survival is not just about overcoming physical challenges but also about maintaining one's humanity in the face of overwhelming odds. The characters are portrayed as flawed yet relatable, navigating their personal struggles while trying to protect one another.
In addition to Darín and Troncoso, the cast features Carla Peterson, Andrea Pietra, Ariel Staltari, Marcelo Subiotto, Claudio Martínez, Orianna Cárdenas, and Ricardo Merkin, all of whom contribute to the rich tapestry of the story. Their performances are enhanced by the show's innovative use of technology, which allows for a seamless blend of live-action and special effects.
The critical reception of O Eternauta has been overwhelmingly positive, with many praising its ability to blend science fiction with poignant social commentary. The series stands out in the landscape of Latin American television, showcasing the region's rich storytelling potential. As the first adaptation of the legendary comic, it not only honors its legacy but also expands upon it, inviting new audiences to engage with its themes.
In a world where the narrative of survival is often dominated by Western perspectives, O Eternauta offers a refreshing take, emphasizing the importance of community and shared experiences. The series challenges viewers to consider their own responses to crises, both personal and societal, making it a timely addition to the genre.
As the first season wraps up, fans are left with more questions than answers, eagerly anticipating what the second season will reveal. With its unique setting, complex characters, and thought-provoking themes, O Eternauta has established itself as a significant work in contemporary television, and its influence is sure to resonate far beyond its initial release.
