‘Backrooms’ Crosses $400 Million at the Global Box Office

Backrooms has passed $400 million at the worldwide box office, turning a low-budget internet-horror adaptation into the biggest theatrical release in A24’s history. Variety reported a global total of $400.09 million after nearly four months in theaters, with $197.5 million from North America and $202.57 million from international markets.

A $10 million production became a global hit

The scale of the result is especially striking beside the movie’s reported $10 million production budget. Variety identified China, Mexico, the United Kingdom, Australia and New Zealand, and France as its leading markets outside the United States and Canada. A site dedicated to the film also noted that an updated Japanese tally helped push the worldwide total beyond the milestone.

Directed by Kane Parsons, the movie grew out of his popular online series about unsettling, seemingly endless rooms known as liminal spaces. The feature stars Chiwetel Ejiofor, Renate Reinsve and Mark Duplass, with its story following a furniture-store operator who discovers a vast network of strange spaces beneath the building.

That digital origin is central to the movie’s success story. Rather than adapting a long-established studio franchise, Backrooms brought a piece of internet folklore—popularized through videos, forums and social platforms—to a mass theatrical audience. Its continued run suggests that online communities can provide more than an opening-weekend burst when the concept also connects with general moviegoers.

The milestone resets A24’s commercial ceiling

The movie had already opened with $81 million domestically and $118 million worldwide, according to Variety. Its new total puts it far above A24’s previous global high and gives the independent distributor an unusually large summer blockbuster without the conventional budget of a major-studio tentpole.

No sequel has been officially confirmed. Parsons has, however, indicated interest in expanding the story, which makes the box-office milestone difficult for the industry to ignore. A continuation would arrive with a proven audience, a recognizable visual identity and expectations shaped by one of 2026’s most profitable theatrical surprises.
