What the movie is

Basic identity

A24 psychological sci-fi horror

Directed and co-scored by Kane Parsons in his feature debut, expanding his viral internet-born Backrooms mythology into a studio film.

Release

May 29, 2026

Theatrical release in the U.S.; by late July it had become one of the year's major horror stories, because apparently endless yellow rooms print money.

Principal cast

Chiwetel Ejiofor, Renate Reinsve, Mark Duplass

Search results also surfaced Finn Bennett and Lukita Maxwell among the supporting cast.

Plot summary

Spoiler-light premise

A furniture store owner named Clark discovers a hidden doorway in his basement and vanishes into the Backrooms: an endless, fluorescent labyrinth of uncanny yellow spaces where normal rules of logic and orientation break down.

Main story engine

After Clark disappears, therapist Dr. Mary Kline enters the shifting maze to find him. The film leans less on conventional monster-forward scares and more on dislocation, dread, memory, loneliness, and mental unraveling.

How critics describe it

Multiple reviews frame the Backrooms not just as a place, but as a psychological and emotional trap: a liminal environment tied to trauma, fractured perception, and isolation.

Reception in one sentence

Critics seem to agree the film is a technical and atmospheric flex; the argument is whether that hypnotic liminal dread adds up to a fully satisfying story or just an expensive panic attack in yellow wallpaper.
