A furniture showroom conceals a doorway into a place that should not exist: a seemingly endless network of connected rooms. Crossing that threshold turns an ordinary interior into an unnerving unknown. Kane Parsons directs this feature-length expansion of the Backrooms concept, with Chiwetel Ejiofor and Renate Reinsve among the cast.

A reason to be curious

Why it may suit you.

If empty corridors and spaces that feel subtly wrong unsettle you, the setting is the main draw here. Its everyday architecture offers a different route into horror, suited to viewers intrigued by disorientation, impossible spaces and the fear of losing their bearings.

Atmospheric horrorInternet-born storiesImpossible spaces

A doorway that changes the meaning of a room

The entrance in Backrooms is not situated in a distant landscape or an obviously forbidden ruin. It appears in the basement of a furniture showroom, an environment associated with ordinary purchases and carefully arranged domestic spaces. Beyond it lies a network of rooms that does not behave like a place a visitor can easily understand or leave.

The premise turns architecture into uncertainty. Normally, a doorway gives useful information about what is on the other side and how rooms connect. Here, entering a space may offer less knowledge rather than more. That makes attention to location, repetition and the boundaries of an apparently familiar interior a natural way to follow the film.

The feature film and its cast

Kane Parsons directs, with Will Soodik credited as screenwriter. Chiwetel Ejiofor plays Clark, Renate Reinsve plays Mary, Mark Duplass plays Phil, Finn Bennett plays Bobby and Lukita Maxwell plays Kat. A24's official description presents the feature around the showroom doorway and the frightening connected spaces beyond it.

Viewers who know the Backrooms concept from online horror will bring their own expectations about empty environments and impossible geography. For a first encounter, that background is optional. The basic dramatic question is self-contained: what should someone do when an ordinary building contains an entrance to somewhere that the rules of the building cannot explain?

How to approach the uncertainty

This is an adult horror and science-fiction selection, with a US R classification for language, bloody images and violent content. Its spatial premise makes it especially relevant to viewers who find the wrongness of a place unsettling even before they know what might occupy it.

A useful viewing approach is to notice how much confidence each new piece of information deserves. A route, a landmark or another person's explanation can seem reassuring without being reliable. Avoid approaching every image as a puzzle that must immediately yield a complete mythology; allowing uncertainty to remain can be part of the attraction of this kind of story.
