Colony (2026)
Original title: 군체
Colony is a 2026 Korean-language action movie directed by Yeon Sang-ho and Choi Gyu-seok, with a running time of 2h 3m. It stars Gianna Jun, Koo Kyo-hwan and Ji Chang-wook.
A mutating virus escapes during a biotech conference, and the authorities seal the building with everyone still inside. Professor Se-jeong and a shrinking group of survivors are trapped as the infected change into something worse by the hour. Yeon Sang-ho, who made Train to Busan, returns to the outbreak with a single-location siege and a cast led by Jun Ji-hyun, Koo Kyo-hwan, and Ji Chang-wook. The pressure builds from confinement as much as from the monsters: locked doors, thinning numbers, and infected whose mutations refuse to hold a stable shape.

A few thoughts on Colony
Yeon builds terror from confinement and mutation, which puts it close to the game The Last of Us, where a fungal infection reshapes both bodies and the people forced to survive them. The claustrophobic siege also recalls the sealed-space panic of Yeon's own Train to Busan, trading the train car for a locked laboratory.
Trapped in one building as an outbreak spreads and mutates
Colony seals a biotech conference building with Professor Se-jeong and the other survivors inside as the infected keep changing. Pontypool traps its cast in a radio station while a language-borne infection spreads outside the door, Containment locks residents into their apartment block under an unexplained quarantine, C.H.U.D. sends something mutated up through the tunnels below a city, and The Last of Us builds its world around this confined, evolving threat.
Zombie stories that run from bleak siege to full camp
Colony plays its outbreak dead serious, a slow-mutating infection with no comic relief in sight. Peninsula, from the same director, pushes that bleakness into a wasteland years after the fall. Grindhouse revives the genre as a gleeful exploitation double-feature, and Poultrygeist and Dead & Breakfast take the infected all the way into full splatstick comedy.
Confinement that turns people, or something worse, feral
Colony's survivors are sealed in with a threat that keeps mutating, and the walls offer no comfort. Attack on Titan puts humanity behind walls against a threat that keeps changing shape, The Cabin in the Woods traps its group with something worse, Lord of the Flies shows a stranded group turning on itself with no monster, and The Hunt keeps that dread of being hunted with nowhere to run.
