The independent horror sensation “Backrooms” has officially crossed the monumental $400 million threshold at the worldwide box office, securing its place as one of the most remarkable commercial achievements in modern cinema history. After a stellar theatrical run spanning nearly four months on the big screen, the low-budget movie has generated an impressive $197.5 million domestically alongside $202.57 million from international markets, bringing its grand worldwide tally to a staggering $400.09 million.
Produced on a modest budget of just $10 million, the surprise horror hit has shattered expectations to become A24’s highest-grossing release of all time. Beyond cementing itself as a milestone for its studio, “Backrooms” stands tall as one of the most fiercely profitable motion pictures of the year, upending conventional industry wisdom and redefining the boundaries of what independent cinema can achieve in a theatrical landscape traditionally dominated by massive, risk-averse blockbusters from major legacy studios.
The visionary force behind the camera is YouTuber-turned-director Kane Parsons, who helmed the project at just 20 years old. Parsons steered the film to unprecedented box office heights, propelled entirely by electric word-of-mouth momentum and fierce, organic enthusiasm from Gen Z audiences. “Backrooms” and “Obsession,” another micro-budget horror smash spearheaded by a young internet creator turned filmmaker, together aggressively upended long-held conventional industry wisdom that younger demographics had lost interest in the theatrical moviegoing experience.
“Obsession,” which was brought to life by 26-year-old director Curry Barker, has similarly stunned Hollywood analysts by generating an incredible $516 million globally against a minuscule production cost of just $750,000. Released by Focus Features—which is owned by Universal Pictures—Barker’s project shares a parallel narrative with “Backrooms,” proving that the next generation of cinematic auteurs are bypassing traditional film school routes and cultivating massive, dedicated followings online before seamlessly translating that digital capital into blockbuster box office receipts.
Fuelled by the stratospheric performance of “Backrooms,” independent powerhouse distributor A24 enjoyed the most lucrative summer season in its history, managing to outperform traditional major studio heavyweights like Warner Bros. and Paramount Pictures in overall market share. This rare market coup marks one of the few instances in modern box office history where an independent distributor has successfully outgrossed a major Hollywood studio during the fiercely competitive summer popcorn season, traditionally recognized as one of the busiest and most high-stakes periods of the year for theatrical exhibition.
A24 concluded the summer blockbuster frame with a robust $237 million in total domestic grosses, securing the fourth-rank position among all major distributors. In doing so, the studio finished comfortably ahead of Paramount, which pulled in $192 million, and Warner Bros., which finished with $165 million. A24 lagged only behind industry titans Universal, which claimed a towering $1.12 billion summer, Sony with $978.8 million, and Disney with $664 million. Focus Features, the studio responsible for distributing Curry Barker’s “Obsession,” operates under the Universal corporate umbrella, further highlighting the remarkable dominance of low-budget, high-concept horror across the broader industry landscape.
The achievements of “Backrooms” within A24’s corporate history are nothing short of historic. By crossing the $400 million mark, the film stands as by far the studio’s highest-grossing movie of all time, towering high above the prior high-water mark previously established by “Marty Supreme,” which finished its run with $192 million. Furthermore, the film delivered the indie distributor’s biggest opening weekend in history, pulling in a massive $81 million domestically and $118 million worldwide during its initial frame. This opening haul more than tripled the previous domestic debut record held by Alex Garland’s acclaimed 2024 thriller “Civil War,” which bowed to $25.5 million.
In addition to studio records, Kane Parsons etched his name into film history by becoming the youngest filmmaker ever to direct a No. 1 film at the box office. Parsons, who was only 20 years old when the film debuted, officially overtook the previous benchmark held by filmmaker Josh Trank. Trank was 27 years old when his found-footage sci-fi thriller “Chronicle” launched in first place at the domestic box office with a $22 million opening back in 2012.
International audiences embraced the eerie, unsettling atmosphere of “Backrooms” just as warmly as domestic crowds. Outside of the United States and Canada, the highest-grossing international territories for the picture included China, where the film brought in $27.8 million. Mexico followed closely as another major market with $17.8 million, while the United Kingdom contributed $17.6 million. Audiences across Australia and New Zealand combined to spend $12.3 million on tickets, and France added another $12.2 million to the global ledger, proving that the internet-born horror phenomenon possessed universal, cross-cultural appeal.
The cinematic adaptation of “Backrooms” is rooted deeply in Parsons’ extraordinarily popular web series exploring the concept of liminal spaces—those unsettling, seemingly endless rooms, sterile office corridors, and labyrinthine structures that originally materialized on the imageboard 4chan before gradually evolving over the years into a massive internet phenomenon across online forums like Reddit and TikTok. The feature film boasts a talented cast featuring Chiwetel Ejiofor, Renate Reinsve, and Mark Duplass. The narrative closely follows an unassuming furniture store operator who stumbles upon an impossible, infinite array of liminal spaces hidden away in the deep, cavernous basement of his workplace.
Although a formal theatrical sequel has not yet been officially confirmed by the studio, Parsons has openly hinted in interviews that he harbors ambitions to transform “Backrooms” into an ongoing cinematic franchise, expanding the mythos of the endless hallways to the big screen on a larger scale. Meanwhile, the unprecedented success of both Parsons and Curry Barker has sent shockwaves through the Hollywood talent ecosystem, leaving every major studio and mini-major production company actively on the hunt to find the next generational YouTube prodigy capable of replicating their miraculous box office magic.
