The ‘Backrooms’ Opening Day Numbers Are in and They’re Absolutely Staggering

Horror cinema rarely announces a genuine turning point this loudly. Kane Parsons, the California-born filmmaker who built a digital mythology from the eerie image of endless fluorescent-lit office corridors, has landed one of the most jaw-dropping debuts the genre has seen in years. His A24 feature, ‘Backrooms,’ has already become a cultural and commercial event before the weekend is even over.

The film’s opening day performance left even the most optimistic tracking figures in the dust, and the industry is now reckoning with what it all means. A movie made for ten million dollars by a director barely old enough to order a drink is rewriting the rules of the box office in real time.

The Opening Day Numbers That Shocked Hollywood

After a thunderous Thursday night preview haul of $10.4 million, ‘Backrooms’ is now on track to open between $76 million and $79 million for its full domestic debut, with some forecasters noting it could hit $80 million across 3,442 theaters. That performance was achieved against a production budget of just $10 million, making it one of the most profitable horror debuts in recent memory.

The Thursday preview take drew immediate comparisons to ‘Five Nights at Freddy’s,’ which earned $10.3 million in previews, and instantly pushed weekend forecasts from the previous $40 to $50 million range all the way up to the $65 to $80 million territory. The scale of that upward revision alone signals how dramatically audience enthusiasm exceeded expectations.

Particularly telling is the demographic breakdown, with a massive 87% of ticket buyers since Thursday night falling in the under-35 category, confirming that Parsons’ connection to his digitally native audience has translated directly to the multiplex.

The film is also expected to cap off what has been a remarkable May for the domestic box office, which has crossed $1 billion in monthly grosses for the first time since 2019, and for the first time ever without a Marvel release driving the numbers.

From Creepypasta to A24’s Biggest Opening Ever

Born in 2005, the same year YouTube launched, Parsons has described the platform as more than a cultural reference, saying it is how he learned to do everything he does. His feature debut makes him A24’s youngest-ever director at just 20 years old.

Parsons, who operates online under the handle Kane Pixels, was 16 when he created his web series, ‘The Backrooms: Found Footage,’ in 2022, itself inspired by a creepypasta image posted to 4chan in 2019 depicting what appeared to be a never-ending expanse of vacant office space. From that unsettling starting point, he built something that resonated globally.

The found footage YouTube series was created using Blender and Unreal Engine and amassed north of 190 million views, catching the attention of A24 and co-financier Chernin Entertainment. The film adaptation follows a therapist and her patient as he shares his discovery of a dimension beyond reality, keeping the psychological dread of the source material intact.

The feature shatters A24’s all-time domestic opening weekend record, previously held by Alex Garland’s ‘Civil War,’ which launched to $25.5 million against a $50 million budget. The comparison is particularly striking given how lopsided the economics are in ‘Backrooms’ favor.

A Certified Fresh Horror Film Built on Liminal Dread

Critics met the film with notable enthusiasm, and that reception became a key factor in the audience surge. ‘Backrooms’ earned a Certified Fresh designation on Rotten Tomatoes with an 88% score based on 104 critical reviews following its theatrical debut, positioning it among A24’s most successful genre releases.

Early professional reviews highlight the film as a triumph of atmospheric worldbuilding over conventional jump-scare mechanics, with particular praise for the opening seven minutes, which critics described as among the most effective horror filmmaking of the year, and a second-act sequence called one of the most bone-chilling things audiences will see in theaters this year.

IndieWire awarded the film a B grade, praising its execution of what they called freaky liminal horror, while Deadline described the film as establishing Parsons as a director to watch. The Metacritic score of 73 confirmed generally favorable reviews across the board.

Parsons himself told Inverse that his goal throughout development was always to create a film that works for his existing audience as well as people who have no familiarity with the Backrooms whatsoever, and the numbers suggest that balancing act paid off on both fronts.

The New Wave of YouTube Horror Directors Reshaping the Genre

‘Backrooms’ does not exist in isolation. It arrives as the centerpiece of a broader shift in where Hollywood is finding its most bankable horror voices.

The film follows the success of ‘Obsession,’ a horror breakout from YouTube creator Curry Barker, which generated $62 million in North America and $84.6 million worldwide after just two weekends of release, having been produced for less than $1 million before its acquisition by Focus Features. The two films are now running simultaneously in theaters, and neither appears to be cannibalizing the other’s audience.

Earlier in the year, YouTuber Markiplier directed, self-financed, and distributed the horror film ‘Iron Lung,’ which earned $50 million against a $3 million budget, further establishing the pattern that online horror creators carry deeply loyal audiences capable of showing up at the box office in force.

The ensemble cast for ‘Backrooms’ includes Oscar nominees Chiwetel Ejiofor and Renate Reinsve alongside Mark Duplass, Finn Bennett, and Lukita Maxwell, with producers including James Wan’s Atomic Monster and Shawn Levy’s 21 Laps Entertainment. The involvement of that level of talent and production firepower signals just how seriously the industry is now taking this new generation of internet-born filmmakers.

Osgood Perkins, director of ‘Longlegs’ and son of ‘Psycho’ actor Anthony Perkins, also served as a credited producer on the film, providing Parsons with a formidable all-star crew around him as he made his big screen transition. For a debut feature, the infrastructure was extraordinary.

Whether ‘Backrooms’ ultimately lands closer to $76 million or crosses the $80 million threshold, the conversation it has started about who gets to direct major horror films has already changed.
