Fresh from its Cannes Midnight world premiere and Korea’s biggest local opening of the year, Colony marks Yeon Sang-ho’s return to the territory he radically transformed with Train to Busan and brings with it a nastier species of panic. Inside a Seoul high-rise, a science conference becomes ground zero for a fast-mutating virus. The authorities seal the building, turning its glass-and-steel corporate order into a slaughterhouse where every floor brings fresh betrayals, brutal calculations, and new ways to die. Gianna Jun stars as a biotech professor trapped in the outbreak, alongside Ji Chang-wook, Shin Hyun-been, Kim Shin-rok, Go Soo, and Koo Kyo-hwan as the scientist at the center of the disaster. Colony is a zombie movie for the AI age: system-based, smart, hungry for more, and moving too fast to contain.
