Netflix Korea has unveiled the highly anticipated second trailer and a striking new poster for the upcoming psychological thriller Wall to Wall, scheduled to premiere globally on July 18, 2025. Directed by Kim Tae-joon, who previously helmed the acclaimed Unlocked, this film continues to build excitement with its dark exploration of urban paranoia and financial despair. Featuring Kang Ha-neul in the lead role, alongside Yeom Hye-ran and Seo Hyun-woo, Wall to Wall promises to deliver a gripping narrative that turns the dream of homeownership into a nightmarish ordeal.
The second trailer, dives deeper into the psychological unraveling of Woo-sung, portrayed by Kang Ha-neul. Unlike the first trailer’s focus on the initial joy of securing an 84-square-meter apartment, this new footage plunges viewers into Woo-sung’s escalating desperation. Brief flashes reveal confrontations with neighbors, including a chilling exchange where Woo-sung is accused of causing the disturbances, his voice cracking as he protests his innocence. The trailer culminates in a haunting visual of Woo-sung standing in a dimly lit room, the walls closing in with geometric overlays, symbolizing the suffocating pressure of his circumstances. The tagline, “아파트가 무슨 죄야, 결국 사람이 문제지” (“What’s the apartment’s fault? Ultimately, it’s the people”), hints at a deeper social commentary woven into the thriller’s fabric.
Accompanying the trailer is a new poster that intensifies the film’s ominous tone. The image centers on Kang Ha-neul’s Woo-sung, his face etched with fear and exhaustion as he clutches the yellow pills. The background features a grid-like pattern of green lines, evoking a blueprint or surveillance grid, which frames smaller portraits of his neighbors—Eun-hwa and Jin-ho—adding a sense of scrutiny and confinement. This visual composition underscores the theme of being trapped, both physically and mentally, within the confines of the apartment complex.
What Wall to Wall Is About
Wall to Wall centers on Woo-sung, played by Kang Ha-neul, a young man who invests everything—his savings, loans, severance pay, and even his mother’s garlic field—to purchase an 84-square-meter apartment, a coveted symbol of stability in South Korea’s real estate landscape. His dream quickly sours as relentless, mysterious noises from neighboring floors plunge him into a spiral of anxiety and financial ruin. Struggling with high-interest debts and plummeting property values, Woo-sung’s attempts to confront the issue are met with hostility from his neighbors, who blame him for the disturbances.
The narrative introduces two pivotal characters: Eun-hwa, portrayed by Yeom Hye-ran, the calculating president of the residents’ association, whose authoritative demeanor masks her own agenda, and Jin-ho, played by Seo Hyun-woo, the suspicious upstairs neighbor whose initial mistrust of Woo-sung evolves into a reluctant partnership to uncover the noise’s origin. Directed by Kim Tae-joon, Wall to Wall transforms the familiar setting of an 84-square-meter apartment into a claustrophobic stage for suspense, blending psychological horror with a critique of societal pressures. The film’s title reflects the standard apartment size in Korea, highlighting the universal experience of urban living while setting the stage for a series of unpredictable twists.
Kang Ha-neul, riding the success of his roles in Squid Game Seasons 2 and 3, brings a raw intensity to Woo-sung, a character teetering on the edge of sanity. Yeom Hye-ran, celebrated for her performances in The Glory and Mask Girl, infuses Eun-hwa with a complex blend of authority and secrecy. Seo Hyun-woo, known from Flower of Evil, adds a gritty edge to Jin-ho, enhancing the film’s tense interpersonal dynamics. With a runtime of approximately two hours, Wall to Wall is set to immerse audiences in a chilling narrative where the boundaries of trust and reality blur, premiering exclusively on Netflix on July 18, 2025.
