Nobody saw this coming, and that is exactly the point. Kane Parsons’ Backrooms earned $38 million domestically on its opening Friday from 3,442 theaters and is projected to gross between $85 million and $90 million through the weekend. Those numbers shatter the previous record for A24’s best opening weekend—Alex Garland’s Civil War, which debuted to $25.5 million in 2024—by more than triple.
A24 is an independent studio that built its reputation on prestige horror, character-driven drama, and filmmakers whose work tends to arrive at the box office through critical momentum rather than franchise recognition. To see the studio’s best-ever opening come from a director whose entire previous filmography exists on YouTube is a statement about how the film industry’s pipeline is changing in ways the traditional development process has not yet caught up with.
Parsons, who built a significant following through his viral YouTube series of the same name, adapted his own mythology into a theatrical horror film about a small-town furniture store owner who discovers a portal to an otherworldly dimension inside his showroom. The cast assembled around him—Chiwetel Ejiofor, Renate Reinsve, and Mark Duplass—is not the roster of a typical YouTube horror production. James Wan, Shawn Levy, and Osgood Perkins serve as producers, while Chernin Entertainment co-financed and co-produced the film.
The infrastructure surrounding Backrooms is entirely professional at every level. What changed is who was sitting in the director’s chair and where the IP originated. Parsons did not pitch a concept to a studio. He built an audience of millions on a platform where the barrier to entry is simply a camera and an internet connection, and eventually, the industry came to him.

The weekend’s broader box office picture makes the Backrooms numbers even more striking in context. Obsession, a horror film from director Curry Barker, now in its third weekend, added $8.1 million on Friday and is projected to reach another $28 million by Sunday, a 19 percent increase over its previous weekend that signals remarkable audience retention.
Meanwhile, Star Wars: The Mandalorian and Grogu fell 70 percent from its opening day to $6.5 million on its second Friday, with projections now pointing toward a $25 million weekend rather than the initial $40 million estimate. Michael, now in its sixth weekend, added $3.5 million on Friday for a projected $12.7 million weekend, pushing its domestic total toward $340 million.
Against that backdrop, Backrooms is not just winning its opening weekend. It is winning by a margin that reframes what A24 can become in theatrical terms and what a YouTube-to-cinema pipeline actually looks like when the film itself is genuinely strong enough to hold an audience.
The studio’s model of backing original, filmmaker-driven work rather than franchise IP has traditionally traded opening-weekend dominance for critical longevity and awards recognition. A debut in the $85 million-to-$90 million range suggests that model no longer has to make that trade if the material connects with audiences on a large enough scale.
What Parsons’ Success Signals for Film
The generation of filmmakers who grew up creating content on YouTube, Vine, and TikTok has been knocking on Hollywood’s door for more than a decade. Conventional wisdom long suggested that the skills required for short-form digital content would not transfer to long-form theatrical filmmaking. Parsons appears to have simply disagreed and made the film anyway.
His Backrooms mythology—the liminal spaces, fluorescent-lit dread, and the unsettling texture of a world that feels adjacent to reality rather than entirely separate from it—translated from a YouTube format designed to hold attention for ten minutes into a theatrical one that demands attention for two hours. That translation is the hardest part, and it is the exact point where most YouTube-adjacent film projects have failed. The projected $85 million opening suggests Parsons achieved it.
The cultural conversation surrounding the Backrooms universe, which predates Parsons’ own work and has existed across multiple internet communities for years, clearly had an audience waiting for something capable of delivering on the mythology’s cinematic potential. Parsons delivered it, and A24 now has the biggest opening weekend in its history to show for the bet it made on him.
