Brought to life using stunning visual effects, the series imagines a nightmarish future when a deadly snowstorm falls on Buenos Aires, although the precise cause is initially unclear.
The series has broken through on the global stage, cracking Netflix's top 10 in several countries beyond Argentina, including the UK – and some of those viewers are now eager to see a second season.
So, here's everything we know so far about the future of The Eternaut.
Will there be The Eternaut season 2?
In an interview with Vogue Spain (translated from Spanish), he said: "Out of contractual and moral obligation, we have to make the second part. It's already agreed upon. When and how, I don't know. It has to be done.
That certainly sounds promising! And not content with one assurance, Darín also told Forbes that the show's creatives have the "second part of The Eternaut ahead of us," for which they intend to "aim higher".
Hopefully, the show's viewership will give the streamer's executives a compelling reason to push ahead, with The Eternaut currently sitting at number four in the UK – which is no small feat for a show not in the English language.
That's based on the production cycle for the first five episodes, which took almost half a year to film and spent approximately 18 months in post-production, polishing up those stunning visual effects.
Nevertheless, we'd estimate that a potential The Eternaut season 2 wouldn't launch on Netflix until summer 2027.
