Backrooms, A24’s upcoming horror, is already frightening horror enthusiasts. Following the release of its trailer, fans are cowering in their seats before they get to theaters, and some are wondering where the found-footage sci-fi got its inspiration.
It turns out that the movie derives from an old 4chan thread, in which a user conceptualized the fear of “backrooms” in fluorescent, “mono-yellow” empty rooms. So, what exactly is the movie about?
Here, News47.us breaks down everything we know about the 2026 Backrooms horror movie.
Backrooms will be released in theaters on May 29, 2026.
Per its logline, Backrooms follows a therapist who must locate her missing patient. Directed by YouTuber Kane Parsons in his directorial debut, the film is partly inspired by his YouTube found-footage anthology series.
Back in 2019, a 4chan user prompted others to share “disquieting” images that resonated with them. One responded with a photo of a yellow-tinged room, similar to the one seen in the 2026 horror film.
“If you’re not careful and you noclip out of reality in the wrong areas, you’ll end up in the Backrooms, where it’s nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in,” the 4chan user wrote about the image. “God save you if you hear something wandering around nearby, because it sure as hell has heard you.”
