Production company BY4M STUDIO has confirmed the new movie release of “Upstairs Neighbors,” a tense comedy thriller set to hit theaters on December 3, 2025. The film, directed by and starring the acclaimed Ha JungWoo, explores the psychological fallout of a seemingly simple neighbor conflict. It features a stellar cast including Lee HaNee, Gong HyoJin, and Kim DongWook, promising a gripping cinematic experience.
A Story of Escalating Neighbor Conflict
The plot centers on two couples living in the same building. Downstairs, Jeonga (Gong HyoJin) and Hyunsoo (Kim DongWook) find their peace constantly shattered by “unusual” inter-floor noise from their upstairs neighbors, Mr. Kim (Ha JungWoo) and Sukyung (Lee HaNee). This common urban frustration sets the stage for a unique and unsettling story about a neighbor conflict that spirals out of control.
The Unexpected Proposal
The tension comes to a head when the two couples decide to have dinner to resolve the noise issue. However, the evening takes a shocking turn when the upstairs husband, Mr. Kim, makes an ambiguous and provocative proposal: “Let’s all do it together.” This single line transforms the atmosphere, shifting the narrative from a simple dispute into a complex web of unspoken desires and psychological suspense. The film is described as a “‘night’ movie without explicit scenes,” focusing on the intense undercurrents between the four characters.
Star-Studded Cast and Direction
“Upstairs Neighbors” marks another directorial effort for Ha JungWoo, who also takes on a leading role. He is joined by a powerhouse cast, making this a highly anticipated Korean movie. Lee HaNee plays Sukyung, the upstairs wife, while Gong HyoJin and Kim DongWook portray the distressed downstairs couple. The film, produced by BY4M STUDIO, has received a Restricted for Youths (R-rated) classification, suggesting mature themes and intense psychological content, similar to what audiences might expect from other complex dramas like the movie ‘Ordinary Family’.
Anticipation for the New Comedy Thriller
With the release of its main poster and trailer, excitement is building for this unique comedy thriller. The promotional materials hint at a story that is both humorous and deeply unsettling, showcasing the chemistry of its top-tier cast. Audiences are eager to see how the talented ensemble brings this story of escalating tension to life. Mark your calendars for December 3, 2025, to witness what happens when a simple noise complaint spirals into something much more complicated and dangerous.
