The “Train to Busan” director is back — and Korean audiences are showing up in massive numbers to prove it. Colony (군체) just rewrote the 2026 Korean box office record books, and it’s only been five days since release.
According to the Korean Film Council’s (KOFIC) KOBIS data, Colony garnered over 2 million moviegoers in just five days, making it the fastest film released in 2026 to reach that milestone at the Korean box office — outpacing The King’s Warden, Salmokji: Whispering Waters, Project Hail Mary, and more.
The records didn’t stop there. Colony also became the fastest film of 2026 to surpass 1 million moviegoers, and achieved the 2 million milestone one day faster than the 2025 hit My Daughter Is a Zombie.
The film re-energised the South Korean box office over the opening weekend of May 22–24, pulling in $9.4 million. Variety

What Is Colony About?
Colony follows Kwon Se-jeong, a biotechnology professor who receives an unexpected invitation from her ex-husband to attend the Chains Bio Conference together. What begins as an awkward reunion quickly erupts into chaos when a rapidly mutating virus is released, transforming the infected into unpredictably evolving forms. The survivors find themselves trapped inside the quarantined building with no way out. Wikipedia
It’s a premise that feels both familiar and refreshingly elevated — exactly what you’d expect from the director who reinvented the zombie film genre for a generation with Train to Busan.
Why Is It Dominating the Box Office?
The combination of Yeon Sang-ho’s pedigree and a star-studded ensemble is clearly connecting with audiences. After attracting global attention with its world premiere at the Cannes Film Festival, Colony has continued its box office momentum, holding the No. 1 spot at the overall South Korean box office since its release.
