Backrooms makes $10.4m in preview screenings [1] ['Rob Beschizza'] Date: 2026-05-29 Liminal horror movie Backrooms is set to become A24's biggest hit, with $10.4 million clipping through in preview screenings, earning back its production budget, and signaling a $40-50 million opening weekend. Alex Garland's "Civil War," the company's previous top earner, made $2.9 million in previews. Adapted by Kane Parsons from his own low-budget, high-concept online series, the film draws from message-board lore an endless maze of faded, yellowing offices, a world inspired by strip malls, business parks, hotel basements and other liminal spaces of suburban America. Parsons' web series documented a fictional research group investigating these eerie environments; in the movie, stars Chiwetel Ejiofor, Renate Reinsve and Mark Duplass are hapless everday explorers. It's been getting good reviews, too, holding an 89% score on Rotten Tomatoes.
