South Korean Zombie Thriller 'Colony' Set for 2026 Theatrical Release and Plot Reveal

Director Yeon Sang-ho's new zombie film Colony will debut in theaters on August 28, 2026, with a later streaming rollout still unannounced. The movie follows biotechnology professor Kwon Se‑jeong, played by Jun Ji‑hyun, who attends a biotech conference that is overtaken by a rapidly mutating virus. The virus creates a hive‑mind of infected individuals that seal the venue, forcing a handful of survivors to navigate a trapped building.

The film’s climax sees Se‑jeong exploiting the infected network’s looped behavior to trigger a system reset, allowing a possible resolution to the outbreak. The project continues Yeon Sang‑ho’s reputation for intense outbreak narratives established with Train to Busan and Peninsula.
