I’ve seen this trick before—the undercover cop, the criminal with a grudge, the shadowy kingpin who may as well be a ghost. It’s a formula that’s launched a thousand crime thrillers, from The Departed to Infernal Affairs to, yes, Johnnie To’s Drug War, the Hong Kong original that Believer remakes. But formulas aren’t the problem; it’s what you do with them.
And in Believer, director Lee Hae-young does something quietly radical: he turns the volume down.
That’s not to say the film is quiet. Believer is an action thriller, after all, and it delivers on the genre’s promises—explosions, shootouts, betrayals, the kind of kinetic energy that leaves you gripping the armrest. But what lingers isn’t the noise. It’s the silence between the bullets.
The way Cho Jin-woong’s Detective Won-ho moves through the world like a man already half-dead, his face a mask of exhaustion. The way Ryu Jun-yeol’s Rak, the low-level dealer turned informant, flinches at the sound of his own voice. These aren’t just performances; they’re studies in restraint, in the weight of choices that can’t be unmade.
Lee Hae-young isn’t interested in the myth of the criminal mastermind. The unseen kingpin at the heart of Believer isn’t some Bond villain monologuing in a volcano lair. He’s a void, a name whispered in back alleys, a face no one can quite remember.
The film’s genius is in how it makes that absence feel like a presence. Every character is chasing a ghost, and the more they grasp at him, the more he slips through their fingers. It’s a metaphor that works on multiple levels—the futility of the drug war, the way power corrupts even those who claim to fight it, the human need to believe in something, anything, even when all the evidence points to emptiness.

Public reportsInside the High-Stakes World of Believer (2018): A Korean Crime Thriller’s Gritty Rise
Lee Hae-young’s Believer (2018) arrived as a relentless Korean crime thriller, blending high-octane action with a labyrinthine drug syndicate plot. Starring Cho Jin-woong, Ryu Jun-yeol, and the late Kim Joo-hyuk, the film quickly became a standout in South Korea’s crime genre, praised for its tension and star-studded cast. But behind the scenes, latestnetflix.com maintains, the production was just as intense as its on-screen chaos.
A Star-Studded Cast with High Stakes
The ensemble cast was a major draw, with Cho Jin-woong (A Hard Day) leading as Detective Jo Won-ho, a cop obsessed with dismantling a drug empire. Ryu Jun-yeol (Reply 1988) played Rak, a low-level dealer caught in the crossfire, while Kim Joo-hyuk (The Servant) delivered a chilling performance as the enigmatic Mr. Lee. Cha Seung-won (Along with the Gods) rounded out the villainous roles as the ruthless crime boss, Brim.

Kim Joo-hyuk’s tragic death in a car accident just months before Believer’s release added a somber layer to the film’s legacy, with many critics noting his final performance as one of his most memorable

Lee Hae-young, known for his stylish thrillers (The Silenced), took a darker, grittier approach with Believer. The film’s original Korean title, Dokjeon (독전), translates to "drug war," reflecting its unflinching portrayal of South Korea’s underground narcotics trade. Unlike glossy crime dramas, Believer leaned into raw, visceral action, with Lee opting for practical effects over CGI where possible .

The movie’s success spawned a sequel, Believer 2 (2023), which shifted focus to Cha Seung-won’s character, Brim, and introduced new players like Han Hyo-joo. However, the original Believer remains the more celebrated entry, thanks to its tighter narrative and emotional weight .
