Is The Gangster The: Cop The Devil Based On True Story

Yes—at its core, it is. The film’s central, unbelievable premise—a mobster and a police officer forming a pact to hunt a serial killer—actually happened in Seoul in 2005. The real-life case of Kang Ho-sung, the "traffic accident killer," provided the blueprint.

However, the film is not a documentary. The characters are composites, the action is hyper-violent and stylized, and the ending is pure cinematic catharsis. The real-life alliance was tense, brief, and pragmatic. The film transforms that pragmatic deal into a blood-pumping, action-packed, darkly comic buddy thriller.

So, the next time you watch Ma Dong-seok sucker-punch a serial killer while handcuffed to a cop, remember: somewhere in a Seoul prison, the real "devil" is still alive. And the only reason he was caught is that a gangster and a cop briefly decided to ignore the law—to serve a darker kind of justice.

The Serial Killer ("The Devil"): The character "K" is widely believed to be inspired by Yoo Young-chul, known as the "Raincoat Killer." Yoo murdered at least 20 people between 2003 and 2004. According to discussions on Reddit, the killer's habit of staging car accidents to lure victims mirrors real criminal tactics from that era.

The Unlikely Alliance: While there is no documented case of a high-ranking "mafioso" testifying in court quite like the film's climax, the concept of police using underworld informants or "gangster" resources to track elusive killers is a recurring theme in South Korean true crime history. 🎭 Fact vs. Fiction

To make the story "theatrical," the filmmakers added specific elements that differ from the gritty reality:

Retribution: Some viewers on Quora point out that the film's ending provides a sense of "cinematic justice" that often eludes real-life cases, where legal red tape and the lack of a death penalty (though it exists on paper in Korea, it hasn't been carried out since 1997) can leave victims' families feeling unsatisfied.
