A24 has officially unveiled the first teaser trailer for Backrooms, offering the most extensive look yet at the highly anticipated horror adaptation of the viral internet phenomenon.
The trailer expands on the eerie teaser released earlier this week, diving deeper into the film’s unsettling liminal spaces, endless yellow corridors, flickering fluorescent lights, and the creeping paranoia that made the original online myth a global horror obsession. The footage emphasizes psychological dread over jump scares, leaning into atmosphere and isolation as its primary weapons.
Directed by Kane Parsons, whose YouTube short films helped popularize the Backrooms mythology, the feature adaptation marks a major leap from viral internet horror to a full-scale theatrical production. The film stars Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, Lukita Maxwell, and Avan Jogia.
A24 confirmed that Backrooms will arrive exclusively in theaters on 29 May 2026, positioning it as one of the studio’s major late-spring horror releases. With the teaser trailer now circulating, early reactions online suggest strong anticipation for how the film will expand the minimalist dread of the original concept into a feature-length nightmare.
As internet-born horror continues to evolve into mainstream cinema, Backrooms could become one of the most fascinating genre experiments of 2026.
