Korean cinema may have found another major winner this year. Director Yeon Sang-ho’s zombie thriller Colony is continuing its impressive run at the local box office, crossing the three million admissions mark during its second weekend in theaters and proving that audiences are still eager for big-screen genre films. The movie first grabbed attention after its world premiere in the Midnight Screenings section of the Cannes Film Festival, but its success at home is now becoming an even bigger story.
Released in South Korea on May 21, Colony has already attracted more than 3.47 million moviegoers and generated nearly $25 million in ticket sales. That performance makes it the second highest-grossing film of 2026 in Korea so far, trailing only the historical blockbuster The King’s Warden. For a zombie thriller competing in a crowded market, those numbers have quickly turned the film into one of the biggest local success stories of the year.
Faster Than One of Korea’s Biggest Hits of 2026
One of the most surprising parts of Colony’s run is the speed at which it reached major milestones. The film crossed three million admissions on its tenth day of release, beating the pace set by The King’s Warden, which needed fourteen days to reach the same benchmark. While it remains far behind that film’s massive overall earnings, the strong start suggests that word-of-mouth and audience interest are helping drive momentum.
The success is also another win for distributor Showbox, which currently has several major titles performing strongly in Korean theaters. Alongside Colony and The King’s Warden, the company is also behind horror hit Salmokji: Whispering Water, which has earned around $22 million since opening in April. Meanwhile, imported titles such as Backrooms, Michael, and Project Hail Mary continue to compete for audience attention, creating one of the busiest theatrical markets Korea has seen in years.
A Zombie Story Led by Gianna Jun
The film stars Gianna Jun, best known internationally for My Sassy Girl, as a biotechnology professor whose trip to a conference in Seoul turns into a nightmare when a mysterious virus begins spreading among attendees. As the infection grows, people start transforming into zombies, forcing survivors into a desperate fight to stay alive. The setup blends Yeon Sang-ho’s familiar horror instincts with large-scale action and social tension, elements that helped make his earlier genre projects popular worldwide.
Industry observers are also viewing Colony as another sign that Korean-produced films are regaining strength after several difficult years at the domestic box office. Six of the ten highest-grossing films released in Korea this year are local productions, including Once We Were Us, Humint, and Choir Of God. That trend is encouraging for studios hoping audiences will continue supporting homegrown movies even as Hollywood franchises and international releases remain strong competitors.
Produced by Wow Point, Smilegate, Midnight Studio, and Showbox, Colony has already secured a broad international rollout. Showbox has reportedly sold the film to more than 120 territories worldwide, including North American distribution through Well Go USA. With strong box office numbers, growing international interest, and positive buzz following Cannes, Colony is shaping up to be one of Korea’s biggest global film exports of 2026.
