Inside Men Prequel Trilogy Just Locked In Ha Jung Woo, Ahn Bo Hyun, Park Hae Joon And Jung Sung Il

One of Korea’s sharpest crime dramas is finally getting the origin story fans have wanted. The prequel trilogy to 2015’s Inside Men has confirmed its lead cast, and it’s a lineup built to dig into exactly how the film’s infamous power cartel came to be.

Inside Men: The Confirmed Cast And Characters

Titled Inside Men: The Birth of the Villains as a working title, the three-part film is set in the late 1980s and traces the events that shaped the media-capital-political cartel at the heart of the original story — think origin story meets slow-burn conspiracy.

Why This Cast Matters

Ahn Bo Hyun steps into particularly high-stakes territory here, playing the younger version of Ahn Sang Goo — a character originally brought to life by Lee Byung Hun in the 2015 film. That’s a big shadow to work under, and it signals just how seriously the production is treating this prequel as connective tissue to the original, not a loose spin-off.

Ha Jung Woo’s Lee Kang Hee, meanwhile, anchors the moral core of the story — a journalist whose ambition and idealism get slowly worn down by the very system he’s trying to expose. Combined with Park Hae Joon’s political operator and Jung Sung Il’s ruthless chairman, the ensemble is built to show corruption forming from multiple directions at once.

Behind The Camera

The trilogy is being co-directed by Kim Min Bum, who worked as assistant director on 12.12: The Day, alongside Kim Jin Suk, known for adapting Made in Korea. The project is currently in pre-production, with filming targeted to begin later in 2026.

Inside Men itself is based on the webtoon by Yoon Tae Ho, the creator of Misaeng — a name that already carries serious credibility in Korean storytelling circles.
