The Backrooms Movie Is Coming to Theaters — A24 Turns a Creepy Internet Myth Into 2026's Scariest Film

The Backrooms: From Viral Internet Horror to A24's boldest 2026 Release

If you've spent any time on the internet in the past few years, you've probably encountered The Backrooms — that eerie, infinitely repeating maze of yellow office rooms that became one of the creepiest internet horror myths to ever go viral. Now, A24 is bringing it to the big screen, and the Backrooms movie is shaping up to be one of the most anticipated horror releases of Summer 2026.

How the Backrooms Became a Movie

The Backrooms started as a 2019 Reddit post featuring a single photo of a liminal space — an empty office with fluorescent lighting and mustard-yellow wallpaper. The image sparked a wave of collaborative worldbuilding, with users creating "levels" of the Backrooms, each more terrifying than the last. Content creator Kane Parsons (known as Kane Pixels on YouTube) took the concept further with his photorealistic CGI found-footage series that garnered millions of views.

A24, the studio behind genre-defining films like Hereditary, Midsommar, and Talk to Me, partnered with Kane Parsons to develop the feature film. Parsons is attached as director, and A24 has reportedly greenlit a budget that allows for ambitious practical effects combined with cutting-edge CGI. The cast includes rising horror actors, though full details remain under wraps — classic A24 secrecy.

Why This Could Be 2026's Biggest Horror Hit

The horror landscape in 2026 is already stacked. We've got Oz Perkins's latest A24 project, Disclosure Day from Steven Spielberg, and the upcoming The Strangers: Chapter 2. But the Backrooms movie has something none of these have: an existing fanbase of millions who grew up with the myth. Internet-native horror has never gotten the big-budget theatrical treatment it deserves — until now.

With A24's reputation for quality horror and Kane Parsons's vision for the source material, the Backrooms movie could redefine how internet horror translates to cinema. Arriving in theaters Summer 2026, it's the film that proves even the creepiest corners of the internet deserve the silver screen.
