The Eternaut is a Netflix Argentine Science-fiction series adapted from the 1957 comic strip El Eternauta by Héctor Germán Oesterheld, one of the most celebrated works of Argentine popular culture. Set in Buenos Aires during an alien invasion, the series spans multiple episodes and marks one of Netflix's most significant Latin American productions in terms of source-material prestige and production scale.

The series entered the media-AI story in June 2026, when Netflix co-chief executive Ted Sarandos confirmed that AI had been used to generate at least one visual-effects sequence. A source cited by Bloomberg identified the tool as Runway, the independent generative-video company. This made The Eternaut the first confirmed Netflix production to use Runway's generative-video platform in final broadcast content, establishing it as the reference data point for the studio's current approach to AI VFX procurement.
