Backrooms sets A24 box‑office record and returns for extended theatrical cut

The horror film *Backrooms* has become A24’s biggest ever release, grossing more than $307 million worldwide – the studio’s first title to break the $300 million mark and the second‑largest horror film of 2026. Made on a budget of under $10 million, the movie opened on Memorial Day weekend and continued to draw audiences, prompting the studio to issue an “Everything Must Go Edition” re‑release on July 3 with 15 minutes of new footage, extending the runtime to two hours and six minutes.

The film, directed by YouTube creator Kane Parsons and starring Chiwetel Ejiofor and Renate Reinsve, was shot in Vancouver and has sparked extensive online analysis. A dominant fan theory now interprets the Backrooms as a collapsing archive of every mind that enters, suggesting the on‑screen entities are degraded copies of previous visitors rather than external monsters. The theory, which points to visual and audio clues throughout the movie, has driven millions of views on video‑essay platforms and reshaped discussions of the film’s horror.

Both the commercial success and the evolving audience interpretation underline the movie’s impact on contemporary horror cinema and highlight the growing influence of internet‑originated properties in mainstream film.
