You’ve seen the Hollywood tropes a thousand times. The "unlikely duo" usually consists of two bickering detectives or a cop and a witness. Boring. What Lee Won-tae did with The Cop, the Gangster, the Devil is something much nastier and, honestly, way more fun. He took a real-life obsession with South Korea’s serial killer history and mashed it into a high-octane noir that feels like a punch to the gut.
It’s 2005. Cheonan is raining. A serial killer is bumping cars from behind and stabbing whoever gets out to check the damage. It’s a simple, terrifying setup. But then the killer makes a massive mistake. He picks on Jang Dong-soo.
Jang isn't a victim. He's a massive, tattoo-covered mob boss played by the legendary Ma Dong-seok (Don Lee). He fights back. He survives. Suddenly, the predator becomes the prey. This isn't just another crime flick; it’s a weirdly symbiotic relationship between a lawman who hates criminals and a criminal who hates being a target.
What Actually Happened: The Real Inspiration Behind the Film
People always ask if this is a true story. Kinda.
While the specific alliance between a mobster and a cop is dramatized for maximum cinematic impact, the atmosphere of the film is rooted in the very real "serial killer era" of South Korea in the early 2000s. Think about the real-life cases of Yoo Young-chul or Jeong Nam-gyu. These were men who terrorized Seoul and its surrounding areas with seemingly random acts of violence. The film captures that specific brand of urban paranoia perfectly.
Director Lee Won-tae didn’t want a generic slasher. He wanted to explore the "grey zone." In the movie, the "Devil" (the killer) is a void. He has no motive. No grand plan. He just kills because he can. This forces the "Cop" (Jung Tae-seok) and the "Gangster" (Jang Dong-soo) to bridge a gap that should be unbridgeable.

The production value here is insane. They spent a fortune making the rainy streets look slick and oppressive. If you look closely at the tattoos on Ma Dong-seok’s back, those weren’t just random stickers. It took a team of artists hours to apply them every single day to ensure they looked like "Kkangpae" (Korean mob) ink. It adds a layer of authenticity that most Western action movies skip.
Why Ma Dong-seok is the Heart of the Movie
Honestly? Without Ma Dong-seok, this movie might have just been another decent thriller.
He has this incredible ability to be terrifying and strangely likable at the same time. One minute he's using a punching bag that—surprise—has a living person inside it, and the next, he's showing a weird sense of honor. He brings a physicality to the role that most actors can't touch. When he hits someone, you don't just see it. You feel it in your teeth.
Contrast that with Kim Mu-yeol, who plays the cop. Kim actually gained about 15 kilograms of muscle just to look like he could stand in the same room as Ma. He plays the character with this manic, caffeinated energy. He's a "bad cop" but for the "right" reasons. He's frustrated by a corrupt, slow-moving system that doesn't care about a few "random" murders.
Then you have Kim Sung-kyu as the killer. He’s haunting. He lost weight for the role to look gaunt and skeletal, a sharp contrast to the hulking mob boss. He barely speaks. He doesn't need to. His eyes do all the heavy lifting.

The "Grey Zone" Ethics of the Partnership
The deal is simple: Whoever catches him first gets to keep him.
If the cop catches him, he goes to jail and the cop gets a promotion. If the gangster catches him, he dies a slow, painful death as payback for the disrespect. This creates a tension that lasts until the very last frame. You’re constantly questioning who you’re actually rooting for. Do you want justice? Or do you want revenge?
It’s a cynical look at the world. The film suggests that sometimes, the only way to catch a monster is to let two other types of monsters off the leash. The police force in the film is portrayed as incompetent and bogged down by bureaucracy. The mob is portrayed as efficient but brutal. It's a "lesser of two evils" scenario that feels surprisingly relevant today.
Why it Succeeded Where Others Failed
Most international audiences discovered this movie through the Cannes Film Festival, where it received a standing ovation. It’s rare for a pure genre film—an action-thriller—to get that kind of high-brow respect.
- Pacing: The movie doesn't breathe. From the first car ramming to the final courtroom scene, it moves.
- Visual Language: The use of neon, rain, and shadow isn't just "cool." It defines the boundaries of the world these characters live in.
- The Ending: No spoilers, but the final scene in the prison is one of the most satisfying "full circle" moments in modern cinema.
The film was so successful that Sylvester Stallone’s Balboa Productions immediately jumped on the rights for a Hollywood remake. The best part? Ma Dong-seok is set to reprise his role. It’s a testament to how irreplaceable his performance is. You literally cannot find another guy who looks like a boulder but moves like a middleweight boxer.

How to Watch It Like a Pro
If you’re going to dive into The Cop, the Gangster, the Devil, don't just watch it for the fights. Watch the power dynamics. Notice how the camera angles change when the Cop and the Gangster are in the same room. Initially, they are separated by physical barriers—tables, car doors, bars. As the movie progresses, they start to share the frame, signifying their blurring moral lines.
Check the background details in the mob's headquarters. The set design tells a story of a man who has worked his way up from the gutter to a position of immense, albeit illegal, power. Everything is pristine, which makes the intrusion of the "Devil" even more jarring.
Also, keep an eye on the side characters. The loyalty of Jang Dong-soo's right-hand man and the skepticism of the Cop's partner provide the necessary grounding for a story that could easily become too "superhero-esque."
Step-by-Step Guide to Korean Crime Noir
If this movie hooked you, you're likely looking for what to do next. The South Korean thriller genre is deep, but it can be overwhelming. Here is how to navigate it without getting lost in the "top 10" lists that all recommend the same three movies.
- Prioritize the "Hardboiled" Sub-genre: Look for films from the mid-2000s to early 2010s. This was the golden age. Start with I Saw the Devil if you want something darker, or The Outlaws (also starring Ma Dong-seok) if you want more action-comedy.
- Analyze the "Social Critique" Layer: Most of these films, including The Cop, the Gangster, the Devil, are actually critiques of the Korean police force or government. Notice the recurring theme of "high-ranking officials blocking the protagonist." This isn't just a plot device; it's a reflection of real-world frustrations in Korean society.
- Follow the Actors, Not Just the Directors: In Hollywood, we follow directors like Nolan or Tarantino. In Korean cinema, certain actors specialize in this "tough guy with a heart" or "menacing villain" archetype. Track the filmographies of Choi Min-sik, Hwang Jung-min, and Song Kang-ho.
- Watch with Original Audio: This is non-negotiable. The cadence of the Korean language, especially the slang used by the "Kkangpae," carries a specific weight that dubbing completely destroys. The honorifics (or lack thereof) between the cop and the gangster tell you exactly who has the upper hand in every scene.
- Look for the Remakes: Watching the original before the upcoming Stallone-produced remake will give you a benchmark for how the "Americanization" of these scripts usually goes. Often, the raw edge of the original is polished away for a broader audience—don't let that be your only experience with the story.
The beauty of this film lies in its simplicity. It doesn't try to be a philosophical treatise on the nature of evil. It just asks: "If you had to team up with your worst enemy to stop a nightmare, could you do it?" The answer, as it turns out, is bloody, loud, and incredibly entertaining.
