Director: Kongkiat Khomsiri
A Japanese wartime experiment goes catastrophically wrong in Operation Undead, a 2024 Thai-Singaporean horror war film pitting green recruits against an army of the reanimated.
What is Operation Undead about?
Set against a fictionalized World War II backdrop, the film follows a company of raw Thai conscripts thrown onto a front line they barely understand. When a covert laboratory experiment run by occupying forces slips its containment, the soldiers face something no training prepared them for: comrades and enemies alike rising again as flesh-hungry husks. Director Kongkiat Khomsiri stages the chaos as much through mud, smoke, and close-quarters gunfire as through practical gore effects, treating the outbreak as an extension of the war itself rather than a separate monster movie. The young unit's commanding officers thin out fast, forcing untested privates into leadership roles they never wanted. Survival hinges less on firepower than on whether the group can hold formation while the line between soldier and creature keeps blurring.
Cast & crew
Chanon Santinatornkul anchors the ensemble as one of the conscripts thrust into command, with Awat Ratanapintha, Guntapat Kasemsan Na Ayudhya, and Thawatchanin Darayon rounding out the squad. The cast plays largely unknown faces to international audiences, which suits a story built around expendable, ordinary soldiers rather than a single hero.
Context & significance
Operation Undead is a Singapore-Thailand co-production released in 2024, blending the zombie-outbreak template with a period war setting rather than a modern-day one. Kongkiat Khomsiri, known for genre work in Thai cinema, leans into practical creature design and trench-level combat staging over CGI spectacle. The film's roughly ninety-minute runtime keeps the outbreak escalating at a steady clip, with the shrinking unit forced deeper into hostile territory as the reanimated numbers grow.
