Backrooms turns internet obsession into an $81 million box office hit

Backrooms did more than open big. It turned a piece of internet folklore into a studio-scale box office event, pulling in $81 million domestically and $118 million worldwide while costing roughly $10 million to make. That kind of opening, powered by a concept born in liminal-space lore on Reddit and 4chan, gives Hollywood a new model to study: low-cost intellectual property with a built-in digital audience.

The film’s first weekend blew past expectations. Variety reported $10.4 million in Thursday previews and said tracking had pointed to a $40 million to $50 million debut, making the final result a substantial overperformance. The movie also shattered A24’s opening-preview record and eclipsed the company’s prior benchmark, Alex Garland’s Civil War, which opened to $25.5 million after $2.9 million in previews.

Kane Parsons, who is 20, directed the film and became A24’s youngest feature director. His YouTube Backrooms series has drawn more than 190 million views, and that online following gave the studio something most new releases lack: years of audience incubation before the first ticket was sold. The Hollywood Reporter said the cast includes Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, Lukita Maxwell and Avan Jogia, with A24 and Chernin Entertainment co-financing and 21 Laps Entertainment and Atomic Monster among the producers. Will Soodik wrote the screenplay.

The business lesson is hard to miss. Backrooms arrived with the economics of an indie but the momentum of a brand. Its $10 million production budget means the film became one of the year’s most profitable releases almost immediately, and its performance suggests that a strong online community can do part of the marketing work studios once paid for through traditional awareness campaigns.

Parsons said at CCXP Mexico that the production built 30,000 square feet of actual backrooms and used Blender to model the sets before they were built in real life. He also said the team ran 50 wallpaper tests to get the right shade of yellow, a reminder that viral ideas still need physical craft to work on a theatrical screen.

The film’s success also came in a crowded marketplace. Disney’s The Mandalorian and Grogu dropped 70% in its second weekend and fell behind Backrooms and Obsession despite playing on far more screens. That contrast underscored a larger shift now visible across Hollywood: creators who built audiences online are beginning to convert those audiences into theatrical buying power.

There is still a catch. If studios strip away the weirdness that made these properties feel native to the internet, the pipeline could dry up. Backrooms showed that the subculture, not just the concept, was part of the asset, and Hollywood’s next test is whether it can scale that energy without sanding it off.
