Hidden Face by Kim Dae-woo is A Steamy Return to the Erotic Thriller, Korean Style

TRAILER

In the current cinematic landscape, where intimacy is often reduced to coy suggestion and sex has all but disappeared from mainstream films, Hidden Face feels almost like an act of defiance. Director Kim Dae-woo’s latest work marks a revival of the erotic thriller—once a staple of both Hollywood and Korean cinema, now largely relegated to the margins in an era of sanitized content designed for universal streaming consumption. With its sultry blend of psychological intrigue, voyeurism, and melodrama, Hidden Face stands as both an homage to a neglected genre and a test case for whether contemporary audiences still have an appetite for films that lean into the carnal as much as the cerebral.

Dae-woo is no stranger to the erotic form. His filmography—Forbidden Quest (2006), The Servant (2010), and Obsessed (2013)—has made him one of Korea’s few directors to consistently treat sexual desire not as garnish but as the engine of drama. With Hidden Face, he returns after a twelve-year hiatus, reuniting with Cho Yeo-jeong and Song Seung-heon, two actors whose careers have crisscrossed his. Their pairing here as a star cellist (Su-yeon) and her fiancé, a conductor (Sung-jin), gives the film a sheen of prestige, as if eroticism itself were being performed by members of a chamber ensemble.

The plot, adapted from the 2011 Spanish-Colombian film La Cara Oculta, is baroque in its contrivances yet irresistible in its execution. Su-yeon, insecure about her fiancé’s devotion, stages a test: she records a farewell video and pretends to leave for Berlin, all the while hiding in a secret, soundproof room concealed behind a bookshelf in their home. The room, equipped with two-way mirrors, allows her to surveil Sung-jin’s reactions to her absence. What begins as a game of manipulation quickly spirals into horror: Su-yeon realizes she is locked inside, trapped with dwindling food, while Sung-jin—believing her gone—falls into the arms (and bed) of her friend Mi-ju (Park Ji-hyun), a fellow cellist drafted to fill her position in the orchestra.


Dae-woo stages this conceit with knowing theatricality. The secret room, at once claustrophobic and perversely luxurious, becomes both Su-yeon’s prison and the audience’s privileged vantage point. It’s impossible not to think of Bong Joon-ho’Parasite, which also used hidden domestic spaces to dramatize class and desire, though here the space is less allegorical and more explicitly voyeuristic. Where Bong mined his subterranean setting for sociopolitical resonance, Dae-woo uses his hidden chamber to explore humiliation, obsession, and the grotesque comedy of watching life unfold from behind glass.

Cho Yeo-jeong, who became internationally known through her dazzling turn in Parasite, is magnetic. Left alone for much of the film’s second act, she embodies Su-yeon’s unraveling with ferocity, oscillating between smug satisfaction and desperate despair. Watching her scrape fungus off expired instant noodles or claw helplessly at the soundproof barrier as her fiancé and best friend make love inches away, one realizes that the erotic thriller is as much about abjection as arousal. Desire here curdles into pathology, and Cho makes every second of Su-yeon’s suffering riveting.

If Cho provides the film’s soul, Park Ji-hyun supplies its intrigue. As Mi-ju, she delivers a performance that balances vulnerability with calculation, leaving the audience uncertain of her motives. Her sexual encounters with Sung-jin—explicit but never gratuitous—carry a deliberate tension: are they acts of genuine passion, opportunism, or revenge? The ambiguity sustains the film long after its central gimmick might otherwise collapse.


By contrast, Song Seung-heon struggles to make Sung-jin more than a cipher. His conductor is less a man than a fulcrum around which two women orbit. That may be intentional—the story is, after all, told primarily through female perspectives—but it leaves his character underdeveloped, particularly when compared with the psychological richness afforded Su-yeon and Mi-ju. What little shading Sung-jin does acquire comes courtesy of his domineering future mother-in-law, played with acidic relish by Park Ji-young. Her sharp, probing questions about Su-yeon’s disappearance inject the film with an energy that borders on black comedy.

Tonally, Hidden Face veers between the plausible and the absurd, and Dae-woo seems to relish the balancing act. The very premise—a woman locking herself in a hidden surveillance chamber to test her lover’s fidelity—demands a suspension of disbelief. But rather than downplay the ridiculousness, Dae-woo leans into it, staging scenes that oscillate between high drama and pulp spectacle. The result is a film that works best in the liminal hours of late-night viewing, when logic gives way to sensation and atmosphere.

What elevates Hidden Face beyond mere titillation is its refusal to treat sex as ornament. The erotic sequences, while undeniably steamy, are integral to the story’s exploration of betrayal and self-delusion. When Su-yeon watches her fiancé consummate his attraction to Mi-ju, the scene is not about prurience but about psychological collapse—the unbearable confrontation of one’s worst fears. Likewise, the eventual revelations about Su-yeon and Mi-ju’s shared history complicate the triangular dynamic in ways that are both erotic and unsettling, culminating in a final image that lingers precisely because it defies easy moral categorization.

In this sense, the film is a reclamation project. Erotic thrillers of the 1980s and 1990s—from Basic Instinct to Body of Evidence—often used sex as spectacle, with women’s bodies objectified in the service of male fantasy. Dae-woo, working with screenwriters Hong Eun-mi and Roh Deok, reframes the genre through a distinctly female lens. The story is less about male conquest than about female rivalry, complicity, and desire. If the film sometimes indulges in pulpish flourishes, it also grants its women narrative control, making them subjects of intrigue rather than mere objects of lust.

Cinematographer Kim Gi-tae underscores this perspective with compositions that emphasize enclosure and reflection. Mirrors abound, literalizing the theme of watching and being watched. The hidden chamber’s glass wall transforms sex into performance, intimacy into spectacle, while the cold palette of the house contrasts with the warm, saturated hues of the concert hall. Music, too, is weaponized: the cello, with its sensual timbre and physicality, becomes a metaphor for both artistic and bodily expression.

Is Hidden Face high art? Hardly. Its pleasures are too brazen, its contrivances too gleeful. Yet to dismiss it would be to overlook its sly intelligence. In a cinematic climate that often treats eroticism as embarrassment, the film is refreshingly unapologetic about its adult sensibilities. It insists, almost provocatively, that sex still belongs on screen—not as a box-office gimmick, but as a fundamental aspect of human experience.

That insistence makes Hidden Face a rarity. It is both trashy and elegant, exploitative and thoughtful, absurd and compelling. It is, in short, exactly what an erotic thriller should be: a mirror game in which desire and deceit refract endlessly, leaving the audience complicit in its voyeurism.

For those who miss the erotic charge once common in cinema, Kim Dae-woo’s return is cause for celebration. For everyone else, Hidden Face may prove a guilty pleasure—or, more accurately, a reminder that pleasure itself need not be guilty at all.

Hidden Face will be released digitally by Well Go USA on September 16, 2025.
