A24 invites you to descend into the unknown with Backrooms, a chilling new found footage nightmare from visionary director Kane Parsons, expanding on his viral series into a full-blown theatrical experience.

Written by Will Soodik and starring Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, and Lukita Maxwell, this is one you’ll want to experience with the lights off—and the exits clearly marked.

The premise is deceptively simple: a strange doorway appears in the basement of a furniture showroom. But once it opens, reality begins to unravel in ways that feel both familiar and deeply wrong. Endless corridors, buzzing fluorescent lights, and the creeping sense that something is watching… waiting.

“Everything must go” takes on a far more sinister meaning here.

Watch the official trailer now and check out the poster for your first glimpse into the maze. Just remember—once you enter the Backrooms, finding your way out may not be so easy.

Backrooms opens exclusively in theaters on May 29, 2026.
