Is The Gangster The Cop The Devil Based On True Story [exclusive] Page

As noted by multiple reviewers, the film's opening titles state it is based on a true story. The film is set in August 2005, and this claim has led many to search for the exact events that inspired it. The film's English title, and its Korean title "Aginjeon" (meaning "The story of evil people"), point to a tale where morality is fluid and every character is, in some way, an antagonist.

According to Wikipedia and IMDb , the movie is indeed inspired by true, real-life events.

The director took the "devil" from the headlines and placed him into a thrilling, fictional scenario to explore themes of justice, vengeance, and morality.

Ultimately, the film's "true story" label is true to the spirit of the events rather than the letter of the law.
