The Roundup 5 began filming on May 24, 2026, after confirming its principal cast and production team. Ma Dong-seok returns as Ma Seok-do, now promoted to team leader in the metropolitan investigation unit, while Kim Jae-young joins the fifth film as new villain Lee Kang-tae.1
The production start was reported on May 27, 2026, with ABO Entertainment cited as the distributor behind the filming announcement. Heo Myeong-haeng, who directed the fourth installment, is directing the new film, and Seo Hyun-woo, Lee Hak-joo, Baek Hyun-jin, and Kim Min-ho are also listed among the cast.1
The Roundup 5 Starts Production With Ma Seok-do Promoted

The new installment follows Ma Seok-do after his promotion to team leader in the metropolitan investigation unit. The story centers on his pursuit of a new type of criminal organization, keeping the film within the crime-investigation framework that has defined the series while changing the central detective’s official role inside the police team.2
Another report describes the case as a crime-suppression operation against an organization that begins moving after an eight-year wait. That detail places the conflict around a long-developing criminal group rather than a short, isolated case, with Ma Seok-do positioned against the organization as the lead investigator.3
Ma Dong-seok is involved not only as the lead actor but also in the screenplay and production. His return keeps Ma Seok-do at the center of the franchise, while the latest storyline gives the character a higher-ranking position in the metropolitan investigation unit.2
Kim Jae-young has been cast as Lee Kang-tae, the new antagonist. The character is described as someone who does not hesitate over methods or means when pursuing his objective, setting up the film’s main opposition between Lee Kang-tae and Ma Seok-do.3
Confirmed Cast and Production Details
The cast list released with the production start includes both franchise lead Ma Dong-seok and several newly confirmed names. Seo Hyun-woo plays Go Young-min, a detective in Team 1 of the metropolitan investigation unit. Lee Hak-joo plays Han Sang-gu, an associate of Lee Kang-tae. Baek Hyun-jin plays Kim Min-cheol, the head of the metropolitan investigation unit, while Kim Min-ho plays a character named Buldak.4

Franchise Context and Public Production Note
The Roundup series remains one of Korea’s most closely watched crime-action film properties. Newsis reported that the second, third, and fourth films each surpassed 10 million admissions, while also summarizing audience figures across the first four installments.4 The fifth film therefore enters production after three consecutive entries crossed that 10 million-admission threshold.
Ma Dong-seok also marked the start of production through social media. StarNews reported that he posted the text “5. #TheRoundup5” with a photo connected to the film’s crank-in, and that ABO Entertainment also announced the May 24, 2026 filming start on the same day.6
StarNews further reported that Ma addressed the participating actors and production team during a script-reading video, expressing gratitude and calling for a shoot that would be enjoyable and free of injuries.6 The available source material does not provide a release date, ticketing schedule, or additional viewing information.

With filming now underway, The Roundup 5 has moved into its production phase with its lead actor, principal antagonist, director, supporting cast, and production companies publicly identified. The confirmed details point to a continuation centered on Ma Seok-do’s expanded police role and a new conflict involving Lee Kang-tae.
