A24 has unveiled a new, deeply unsettling trailer for the forthcoming horror feature, Backrooms. This movie adaptation is helmed by Kane Parsons, who is notably one of the youngest directors ever to collaborate with the studio.

The Vision Behind The Backrooms Adaptation

Kane Parsons' Digital Origins

The film is based on the original web series created by Parsons himself, who operates online under the username Kane Pixels. Parsons first launched his horror series in 2022, focusing on an organization dedicated to investigating the titular Backrooms.

The concept centers on seemingly endless hallways and rooms existing in an alternate dimension, filled with cryptic secrets. The new trailer suggests a feature film expansion of this established, eerie lore.

Trailer Reveals Story and Key Characters

A Discovery and A Descent

The trailer introduces a narrative centered on a furniture store owner who finds an entry point into the Backrooms concealed within a wall of his building. He discusses this bizarre location with his therapist, noting that the space appears to contain objects spanning various time periods.

The footage then shifts to showcase actor Ejiofor and a group navigating the Backrooms while filming, encountering previously unseen threats within the maze-like environment.

Promises of Terror and Involvement

The trailer also highlights the involvement of actress Reinsve's character. She is seen stepping through a door opened by Ejiofor’s character, seemingly entering the dimension to locate him. However, subsequent scenes show her bloodied in a hallway, heavily implying major horrors await.

The visuals also feature individuals wearing hazmat suits, a nod to elements present in Parsons' original web series. It remains unclear exactly how the movie will integrate with the existing canon storyline, if at all.

Understanding The Backrooms Phenomenon

From Internet Legend to Cinematic Horror

The Backrooms originated as an Internet urban legend back in 2019. An anonymous post on 4chan featured an image of empty rooms characterized by dividing walls and carpeting, claiming the dimension was accessible by accidentally falling out of reality.

Since its inception, the concept has spawned numerous interpretations online. These range from the location being a simple, unsettling empty maze to a complex structure involving multiple layers inhabited by unexplained creatures.

Expanding The Lore

Parsons' web series became the most popular interpretation, blending unnerving emptiness with stalking creatures. The 2026 horror film promises to significantly expand this lore through the perspective of the accidental discoverer.

While the original series often utilized found footage and cryptic presentation, the movie format allows for a more concrete and direct laying out of these elements. This transition also grants the concept a larger budget to explore the compelling ideas that made the source material successful.

Release Outlook

The film is slated for a theatrical debut on May 29, 2026. While the movie does not explicitly promise answers—which could risk diminishing the mystery central to the Backrooms—it strongly indicates a terrifying story connected to the established Internet lore. Given its proximity to release, more details may remain under wraps until the premiere.
