Colony opened in South Korea on May 21, 2026, with most box office reports placing its first-day audience at 199,759 admissions, enough to lead the daily chart and mark the strongest opening score among 2026 releases so far. The Colony Box Office result also came with a reported 74.6% revenue share, putting director Yeon Sang-ho’s new infection thriller far ahead of the day’s other releases.1
The opening-day figure was reported by multiple outlets citing the Korean Film Council’s integrated ticketing network, while one separate SBS Entertainment News report gave a lower morning-based count of 185,532 nationwide admissions.2 The broader consensus across Yonhap News, Star News and Kookmin Ilbo centered on 199,759 viewers for the film’s first day.3
Colony Opening Day Audience Count

Colony reached nearly 200,000 moviegoers on its first day of release, a notable result because the film opened on a Thursday rather than at the start of a weekend. Kookmin Ilbo described the performance as unusual in light of that weekday release timing and noted that the gap between Colony and the second-ranked film Michael was about 170,000 viewers.4
Star News reported that Michael placed second on the same daily chart with 29,293 viewers, underlining how sharply Colony separated itself from the rest of the day’s box office.3 The film’s opening also surpassed the previous 2026 opening benchmark set by The Devil Wears Prada 2, which had drawn around 150,000 viewers on its first day, according to comparisons carried by Kyunghyang Shinmun and Star News.5
The official first-day status gave Colony both the No. 1 daily box office ranking and the year’s highest opening score among 2026 releases reported to that point. Yonhap News also reported that advance reservations remained strong on the morning of May 22, with reserved viewers at roughly 260,000, keeping the film in the lead after its debut day.1

Box Office Comparisons and Reservation Momentum
The central box office comparison in the reports was against The Devil Wears Prada 2, previously identified as the highest-opening 2026 release before Colony. Star News said Colony’s first-day result was more than 48,000 admissions above that earlier opening.3 Kyunghyang Shinmun also reported that Colony had moved past the opening results of The Devil Wears Prada 2 as well as domestic hits The Man Who Lives with the King and Salmokji.5
Reservation data suggested that interest had been building before release. Hankook Ilbo reported that, as of 10 a.m. on May 17, Colony held the top overall reservation position with a 29.7% reservation rate and 95,766 reserved viewers.6 By May 22, after opening day, Kyunghyang Shinmun reported a reservation rate of 49.3%, while Yonhap News cited roughly 260,000 reserved viewers that morning.5
SBS Entertainment News also pointed to pre-release demand, reporting that the film had exceeded a 50% reservation rate and 200,000 reserved tickets before opening. The same report gave the production cost as 17 billion won and the break-even point as 3 million viewers, while describing the first weekend performance as a key factor for the film’s wider commercial trajectory.2
Film Context Behind the Opening
Colony is a new film from director Yeon Sang-ho and features Jun Ji-hyun, Koo Kyo-hwan, Ji Chang-wook, Shin Hyun-been, Kim Shin-rock and Go Soo, according to Kookmin Ilbo’s report on the opening-day result.4 Hankook Ilbo described the film as an infection thriller about survivors inside a sealed-off building facing evolving infected people.6
The film also arrived in theaters after international festival exposure. Hankook Ilbo reported that Colony was invited to the Midnight Screening section of the 79th Cannes Film Festival, where it was first shown locally and was followed by about five minutes of applause and cheers after the screening.6 Kyunghyang Shinmun also referenced the Cannes Midnight Screening invitation while reporting the domestic opening-day performance.5
The available figures show a clear first-day lead for Colony, with 199,759 admissions widely reported, a 74.6% revenue share, and continued reservation strength on May 22. Its next measurable test is whether those opening-day and reservation figures translate into sustained weekend attendance and progress toward the 3 million-viewer break-even point reported by SBS Entertainment News.

In immediate box office terms, Colony began its run as South Korea’s top daily film on May 21, 2026, and as the strongest reported opening among 2026 releases so far.
