Backrooms is a 2026 horror film from A24, the feature directorial debut of Kane Parsons, who created the viral YouTube web series of the same name while still a teenager. Adapted and expanded from that internet phenomenon, it brings the "liminal space" creepypasta, endless humming corridors of deserted, fluorescent-lit rooms, to the big screen.
The story follows characters who slip out of ordinary reality into an ever-shifting dimension of empty hallways, stalked by things that lurk in its monotony. Chiwetel Ejiofor and Renate Reinsve lead the cast, alongside Mark Duplass, Finn Bennett, and Lukita Maxwell, as the trapped survivors race to find a way back before the maze swallows them whole.
Made for a reported $10 million, Backrooms became a surprise phenomenon, grossing more than $400 million worldwide and drawing strong reviews, with an 86% score on Rotten Tomatoes, for Parsons's assured, unnerving direction; he became the youngest filmmaker ever to top the U.S. box office. After a theatrical and digital run, the film arrives on HBO Max on September 25, 2026. On HBO Max.
