Backrooms Official Trailer

A24's horror film Backrooms begins when a strange doorway appears in a furniture showroom basement. Director Kane Parsons expands his online short-form work into a feature narrative.

An unidentified door appears in the basement of a furniture showroom. Backrooms is a horror film that begins with this brief, concrete incident and confronts us with a strange space opening inside an ordinary place. The official trailer alternates between the familiar textures of an interior and spaces beyond it, hinting at what the characters will discover.

The film is directed by Kane Parsons. After creating his own series of Backrooms short films online, he completed a feature-length film with this work. In a conversation released by A24, Parsons explains that he wanted to move beyond the existing found-footage format and place the characters played by the actors and their relationships at the center.

The film stars Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, and Rukiye Maxwell. It is a production from A24 and Chernin Entertainment, and the production team built a set spanning approximately 30,000 square feet on a Vancouver soundstage to realize the space.

Parsons says that the horror of this world arises not from dark, grotesque decoration, but from the idea that bright, ordinary-looking spaces can continue endlessly. Following that perspective, the trailer transforms a familiar interior into a place of unsettling exploration and shows that the feature film has been designed to let new audiences enter this world as well.
