The viral internet horror phenomenon Backrooms is heading to theaters in 2026, bringing the eerie concept of endless liminal spaces to the big screen. Directed by Kane Parsons and distributed by A24, the upcoming film adapts the unsettling online myth that imagines a hidden dimension of identical yellow rooms, buzzing fluorescent lights, and endless corridors.
Inspired by Parsons’ massively popular found-footage YouTube series, the movie expands the mysterious world of the Backrooms into a full cinematic story. While specific plot details remain limited, the film centers on characters who find themselves trapped in the strange dimension, where reality begins to unravel and escape may not be possible.
The cast includes Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, Lukita Maxwell, and Avan Jogia.
With its unsettling atmosphere and origins in internet folklore, Backrooms aims to transform one of the web’s most recognizable horror legends into a theatrical experience when it arrives in theaters on May 29, 2026.
