The U.S. box office witnessed one of its most dramatic weekends of 2026 as Backrooms delivered a sensational $81.4 million domestic debut, rewriting expectations for horror cinema, internet-born storytelling, and independent theatrical filmmaking in the process.
The breakout horror phenomenon not only scored the biggest opening weekend in A24 history, but also emerged as one of the largest horror openings of the year. Globally, the film opened to more than $118 million, an astonishing result for a project reportedly produced on a budget below $10 million.
Directed by 20-year-old filmmaker Kane Parsons, Backrooms became one of the most surprising box office stories of the year after massively overperforming beyond industry projections. Early tracking initially suggested a debut in the $20 million range before estimates gradually climbed to $45-$55 million in the days leading up to release. By opening weekend, however, the film had exploded into $80 million territory as presales, walk-up demand, and late-night screenings surged across the country.
The film earned approximately $38.4 million from Friday and preview screenings combined, while premium formats and late-night horror showings reportedly sold out in multiple markets. Trade analysts repeatedly pointed toward unusually strong Gen Z turnout and repeat-viewing interest as major factors behind the movie’s extraordinary performance.
The opening also shattered the previous A24 record held by Civil War, signaling a major commercial breakthrough for the studio’s horror division. What makes the achievement even more remarkable is the film’s origin story. Backrooms evolved from the viral internet horror mythology surrounding liminal spaces and analog horror culture, while Parsons himself first gained recognition through YouTube horror shorts before transitioning into feature filmmaking.
The strong opening was further boosted by positive critical reception. Early reactions praising the movie’s atmosphere, immersive sound design, and psychological horror helped elevate audience interest throughout the weekend. Momentum surrounding the film had already intensified after the widely discussed Backrooms review roundup and the movie’s rapidly growing tracking numbers in the days before release.
While Backrooms dominated the weekend, Obsession continued its extraordinary theatrical run with another massive hold in its third weekend. The horror breakout earned approximately $26.4 million domestically, pushing its North American total beyond $104 million and its worldwide gross above $150 million.
The Curry Barker-directed thriller has now become one of the biggest sleeper horror success stories of the year, with its theatrical momentum increasingly drawing comparisons to legendary long-running box office phenomena. Trade observers have repeatedly highlighted the film’s unusually strong second and third weekend holds, a rarity for wide horror releases outside major holiday corridors.
Driven heavily by Gen Z audiences and word-of-mouth buzz, Obsession has transformed from a modest genre release into a full-scale cultural and commercial breakout. The movie’s historic second-weekend surge has remained one of the most discussed box office stories of the season and further reinforces horror’s dominant position in the current theatrical marketplace.
Meanwhile, Star Wars: The Mandalorian and Grogu suffered a sharp second-weekend collapse, earning approximately $25 million domestically and falling to third place behind both Backrooms and Obsession. The steep drop, reportedly close to 70%, has intensified industry conversations surrounding franchise fatigue within the broader Star Wars brand.
The contrast between the weekend’s top performers became a major talking point across Hollywood trade circles. While Backrooms reportedly cost under $10 million to produce, The Mandalorian and Grogu carried a reported production budget near $165 million. The symbolic image of two low-budget horror projects outperforming one of Hollywood’s biggest legacy franchises quickly became the defining narrative of the weekend.
Outside the top three, several other major titles continued posting solid numbers across the domestic Top 10. Michael added another $11.7 million, lifting its domestic total close to $340 million and continuing its impressive theatrical run. The Breadwinner debuted with approximately $7.5 million, while The Devil Wears Prada 2 added another $5.9 million and crossed $209 million domestically.
Elsewhere, Pressure opened with roughly $5.75 million from under 2,000 theaters, while family title The Sheep Detectives continued its stable run with $4.6 million, pushing its domestic total beyond $54 million. Passenger added another $2.6 million, and Mortal Kombat II remained inside the Top 10 with $2 million, bringing its domestic total close to $78 million.
The overall weekend reflected strong audience turnout across horror films, music-driven biographical dramas, family entertainment, and franchise holdovers. Still, the overwhelming conversation across the industry belonged to horror cinema and a younger generation of internet-native filmmakers reshaping theatrical success stories.
With Backrooms rewriting expectations and Obsession continuing one of the year’s most remarkable theatrical runs, the domestic box office weekend ultimately belonged to horror films and original genre storytelling.
