'Train to Busan' director Yeon Sang-ho returns with zombie film 'Colony' starring Gianna Jun

South Korean director Yeon Sang-ho returns to the zombie genre with "Colony," his third live-action thriller and a new chapter in his self-built cinematic universe. The film stars Gianna Jun (Jun Ji-hyun) in a long-awaited comeback role. Where "Train to Busan" showed humans cannot outrun the infected, "Colony" argues they cannot outsmart them either.
