Backrooms tracks to stunning $76 million to $79 million opening

Backrooms had become the kind of opening Hollywood rarely sees anymore: a low-cost, internet-born horror movie tracking toward $76 million to $79 million, after a $33 million to $35 million Friday that included $10.4 million in Thursday-night previews across 3,442 theaters. The scale of the run stunned an industry still waiting for franchises to restore consistent turnout, and the audience makeup made the signal even clearer, with 88% of moviegoers under 35 and 18- to 24-year-olds accounting for 43% of the crowd.

The film’s momentum pointed to a simple shift with big box-office consequences. Backrooms came from Kane Parsons, a creator who honed his instincts on YouTube, and The New York Times framed the film as part of a broader wave of breakout projects from directors with that background. In other words, theatrical success was no longer coming only from familiar studio brands or established franchise machinery. It was also coming from internet-native ideas that already had built-in recognition before they reached multiplexes.

A24 listed Backrooms as directed by Parsons, written by Will Soodik and starring Chiwetel Ejiofor and Renate Reinsve. The film centers on a strange doorway that appears in the basement of a furniture showroom, a premise that is odd enough to be memorable and simple enough to travel fast through online culture. Even the commercial setup looked unusually strong: TheWrap reported $10.4 million in Thursday previews and at least $13 million in Friday presales, while the weekend was projected to more than triple A24’s previous wide-opening record of $25.5 million set by Civil War.

The numbers carried more meaning because the genre is proving how efficiently it can scale. Deadline reported that premium large-format screens accounted for 17% of the weekend and that Backrooms earned a CinemaScore of B-, a reminder that horror can thrive even without universal audience enthusiasm if the concept lands hard enough with the right demographic. That is the economics of the moment: audiences want something new, and horror keeps offering the most affordable path to a theatrical event.

The same dynamic was visible elsewhere in the market. Focus Features’ Obsession, a $750,000 horror film that opened May 15, had already earned north of $68 million domestically by May 27, and Deadline projected a $106.8 million domestic finish, which would make it Focus Features’ highest-grossing domestic title. TheWrap said May 2026 was on pace to push domestic grosses past $1 billion for the first time since 2019, and, it said, for the first time ever without a Marvel release. Backrooms was not just a breakout. It was evidence that the current theatrical market is rewarding original, lower-cost genre films with a speed and scale that older franchise models are struggling to match.
