THE ETERNAUT is a new Netflix Sci-Fi Series from Argentina (org. title: El Eternauta).  It’s a typical summer night in Buenos Aires, when suddenly all power goes out and snow starts falling.

If this wasn’t strange enough in itself, people also drop dead if caught out in the snowfall. This is just the beginning of what we’ll experience in the apocalyptic world of the Netflix series. It’s based on a graphic novel, and season 1 has 6 episodes.

Winter in the Argentine Summer

In the Argentine sci-fi series The Eternaut, we’re following survivors of a strange and devastating toxic snowfall. It’s the middle of summer when a rare snow begins falling in Buenos Aires. One second it’s a warm summer night, the next it feels like the dead of winter.

Of course, if you’re caught out in the snow, you don’t have to worry about being cold; You’ll be dead before you know what’s going on as the snow kills everything it touches in an instant.

But where does the snow come from, and how can we battle it? Especially when everything electric and electronic we’ve come to rely on has also stopped working. Again, the power just went out from one second to the next.

The power outage wasn’t a huge shock to the people of Buenos Aires. Blackouts were already an issue for the people of the big city, which we see people complaining about and even rioting over.

Could this sudden toxic winter be the result of a nuclear war, or is something even stranger going on?! One thing is certain: If you want to survive, you need to suit up in gas masks and layers of clothes to stave off both the toxic snow and freezing cold.

Also, as always, you have the other survivors to worry about.

Who might you know from the cast of The Eternaut on Netflix?

Emerging as a leader of the resistance against the threat, which is very much out of this world, is a man named Juan Salvo. As the character Juan Salvo, we see the popular Argentine actor Ricardo Darín (The Secret in Their Eyes).

Other core characters are portrayed by Carla Peterson (Blondi), César Troncoso (Yosi, the Regretful Spy), Andrea Pietra (An Unexpected Love), Ariel Staltari (Pipa), Marcelo Subiotto (The Crimes that Bind), Claudio Martínez Bel (Rojo), and Mora Fisz (Tierra Incógnita).

Whether you know these actors beforehand or not probably depends on how many Argentine productions you’ve watched prior to The Eternaut. And in any case, you should enjoy their performances in this wild sci-fi story on Netflix.

A Gorgeous Netflix Sci-Fi Series set in Argentina

With this Netflix series, we’re getting the first screen adaptation of an iconic Argentine sci-fi graphic novel. “The Eternaut” (or El Eternauta in its original Spanish) was written by Héctor G. Oesterheld and gorgeously illustrated by Francisco Solano Lopez.

Once again, we’re dealing with a story that feels fresh and current despite being decades old. The Eternaut graphic novel was first published in 1957, so we’re talking about a core plot that first saw the light of day more than 50 years ago. In fact, it’s closer to 60 years.

Of course, this Netflix screen adaptation is a huge undertaking that has been in the works for quite some time. We’re talking 2 years of development and scriptwriting, followed by 4½ months of pre-production, and then came 148 days of filming in Buenos Aires.

The actual filming included 2,900 actors (including extras, obviously), over 50 locations, and 30 virtual stages, plus more than 500 masks for the series’ characters.

Finally, as with any sci-fi production, that’s only the beginning, as the pre-production and filming were followed by more than 18 months of post-production.

Watch season 1 of The Eternaut on Netflix now!

This new Netflix series was directed and created by Bruno Stagnaro, who wrote the script along with actor Ariel Staltari. Clearly, Bruno Stagnaro has much love for the original story and has ensured that this adaptation is in the spirit of the original graphic novel.

As mentioned already, this Netflix series is based on the 1957 graphic novel from Argentina. This was written by Héctor G. Oesterheld and illustrated by Francisco Solano Lopez. This Netflix screen adaptation is Bruno Stagnaro’s, made with the vision of its creators in mind.

The first season consists of 6 episodes, and you’ll want to note that this is from the official press material. The “first season” part, I mean. Hopefully, this means we’ll get The Eternaut season 2 soon, now that all the groundwork has already been done for season 1.
