Netflix Leverages AI in 'El Eternauta,' Accelerating VFX Production

Streaming leader Netflix has deployed generative AI tools in its Argentine sci-fi series El Eternauta, marking a significant step in the company's technological adoption. The post-apocalyptic show, which premiered in April 2025, utilized AI to create complex sequences like a collapsing Buenos Aires building - achieving what co-CEO Ted Sarandos describes as "remarkable results at amazing speed."

The AI Advantage in Production

According to Netflix executives:

• VFX workflows accelerated 10x compared to traditional methods
• Enabled advanced techniques like "age reduction" on TV budgets
• Assisted with pre-visualization and shot planning

The series contains approximately 2,000 VFX shots, with Deadline reporting producers turned to AI solutions to manage tight schedules and budget constraints. While Netflix hasn't disclosed the specific software used, Sarandos emphasized during an earnings call that AI presents "an incredible opportunity to help creators make better movies and TV shows."

Industry Backlash and Quality Concerns

The move comes amid ongoing tension in entertainment sectors:

• 2024 Hollywood strikes included demands for AI protections
• Creatives express fears about job displacement
• Some AI-generated content faces criticism over artistic integrity

Netflix previously faced scrutiny for using AI-processed images in true crime documentaries and reconstructing a murder victim's voice via AI. Other streamers like Amazon have also experimented with AI applications including:

• Automated show recaps
• Content recommendation engines
• AI-assisted dubbing services

Key Points

• Netflix's El Eternauta represents the platform's most significant AI integration to date
• Production efficiencies come with ongoing debates about creative impacts
• The industry continues grappling with balancing technological potential against workforce concerns
• Streaming competitors are pursuing parallel AI development paths
