Jun Ji Hyun returns to the big screen for the first time in 11 years, leading a cast of actors each bringing distinct personalities and backstories — setting the stage for a deeply immersive ensemble performance. soompi
3. Dancer-choreographed creature movement and world-class production design
The infected’s eerie movements were crafted in collaboration with dancers, delivering a distinctly unsettling style of fear. The special makeup team behind Train to Busan‘s iconic zombies and the action director from The Roundup: Punishment combined forces to create original creature designs and vivid action sequences — while large-scale sets and immersive filming are designed to make audiences feel like they’re trapped inside the building alongside the survivors.
