Overview

• Netflix launched the eight-episode drama on September 19, introducing a high-concept story set in Kimera, a secret atomic bunker for Spain’s ultra-wealthy.
• The premise centers on elite families taking refuge as global conflict erupts, framing an explicit class critique that cast members describe as an 'eat the rich' reading.
• Early interviews highlight a surprise at the end of episode one without revealing details, with actors saying it reframes how viewers see the story.
• The production built a sprawling, meticulously detailed set at Netflix’s Tres Cantos hub in Madrid, using a stage of over 7,000 square meters and in-camera virtual effects with a 30x6 meter LED wall.
• Actors describe an intense, claustrophobic shoot lasting months—one cited eight months on set—and say the creators aimed for realism that reflects truth manipulation and current geopolitical tensions, with no second season confirmed.
