A horror film built from an internet myth and directed by a 20-year-old has handed A24 the biggest opening weekend in the studio’s history. Backrooms, directed by YouTube phenomenon Kane Parsons, grossed $81 million domestically and $118 million worldwide in its May 29–31 debut, more than tripling the $25.5 million record set by Alex Garland’s Civil War in 2024. Against a production budget of roughly $10 million, the result is not just a record but a windfall, and a signal that the gap between online creators and Hollywood has effectively closed.
The numbers reframe what an independent studio can do. A24’s previous best opening came nowhere near this; Backrooms outgrossed even Star Wars: The Mandalorian and Grogu, which opened to $81.6 million the prior weekend on a Disney marketing campaign approaching $100 million. By contrast, the Backrooms campaign was small and surgical, aimed squarely at the fans who already knew the property.
From Liminal-Space Meme to Marvel-Sized Debut
The film’s origin is the story. Backrooms is based on Parsons’ web series about liminal spaces — eerie, seemingly endless rooms that gained traction on Reddit and TikTok. The plot follows a furniture store owner, played by Chiwetel Ejiofor, who discovers a hidden doorway into an endless stretch of nondescript rooms; when he vanishes, his therapist, played by Renate Reinsve, goes in after him. Parsons’ original anthology web series had already amassed nearly 100 million combined views before the feature existed.
That built-in audience translated directly into ticket sales. Roughly 88% of the opening-weekend crowd was under 35, with the audience skewing 62% male. Industry analyst Jeff Bock of Exhibitor Relations attributed the Marvel-sized result to an obsession with the Backrooms mythology itself. For a studio release, the reception looked less like a marketing rollout and more like a community event years in the making.
A Record-Breaking Filmmaker at 20
Parsons’ age makes the achievement historic on a second front. At 20, he became the youngest filmmaker ever to direct a No. 1 film at the domestic box office, breaking the record held by Josh Trank, who was 27 when Chronicle opened to $22 million in 2012. The opening also set the record for the largest debut ever for a first-time director working with an original film.
The marketing leaned into the property’s native habitat rather than fighting it. A24 seeded in-world Easter eggs for fans, including a fictional flyer and a fax number for audience submissions, and dropped an in-world commercial on Reddit a month before release. Social-media analytics firm RelishMix measured the film’s online footprint at 220 million across platforms, 48% ahead of typical original-horror norms, and reported audiences treating the film as the culmination of a long-running internet phenomenon rather than a conventional studio product.
The Economics of Internet-Native IP
What makes Backrooms consequential beyond its own ledger is what it proves about a business model. Hollywood has spent years lamenting its inability to pull the YouTube generation into theaters, watching the 18-to-25 demographic show up for franchise tentpoles but little else. This year cracked that problem open: it began with YouTube star Markiplier’s self-distributed Iron Lung, which opened to $17.8 million, and escalated through Focus Features’ acquisition Obsession before Backrooms became the pinnacle.
The financial logic is hard to ignore. A property with a pre-existing audience of millions arrives with its marketing half-done, and a $10 million budget against an $81 million opening rewrites the risk calculus that governs greenlighting. Studios accustomed to spending nine figures to manufacture awareness are now watching a creator deliver it for free, built over years of uploads. The question facing the industry is no longer whether internet-native IP can perform theatrically, but how quickly studios can identify and partner with the creators who already command those audiences.
What Comes Next
A sequel has not been formally announced, though Parsons has teased the idea of expanding Backrooms into a film franchise. Given the economics on display, a follow-up looks less like a possibility than an inevitability. The more lasting effect may be structural: every studio development executive now has a concrete data point arguing for mining YouTube, Reddit, and TikTok for the next built-in fanbase.
For A24, a studio that built its brand on prestige and auteur-driven risk, the irony is that its biggest commercial moment came not from a festival darling but from a meme. The film that broke its records was born in the same endless, fluorescent-lit rooms its characters can’t escape — and Hollywood, for once, seems eager to follow the internet inside.
