A24's Record-Breaking Horror Hit 'Backrooms' Gets HBO Max Release Date

Clear out your schedule and turn off the lights, because the biggest indie box office hit of the season is finally headed to your TV screens. The viral sensation turned theatrical monster *Backrooms* has officially secured its home platform debut. Fans will be able to stream the terrifying A24 feature exclusively on HBO Max beginning September 25. The news comes on the heels of a historic box office streak for the distributor. The movie officially dethroned *Marty Supreme* to become A24's highest-grossing theatrical release in the studio's history. It is an incredible milestone for a project that originated as an internet sensation focused on eerie, unnerving liminal spaces before capturing global attention in multiplexes. ## What is the Backrooms HBO Max release date? Moviegoers who missed the theatrical run will get their chance to dive into the surreal maze on Wednesday, September 25, when the title joins the HBO Max catalog. The home release allows audiences to pause, rewind, and obsess over every creepy detail of the mysterious nightmare world at their own pace. The film was brought to the big screen by director Kane Parsons. Parsons helmed the adaptation based on his own viral web series, which initially skyrocketed to fame online by exploring the concept of slipping out of physical reality into endless, empty rooms. Bringing that distinct aesthetic to a major feature film proved to be a goldmine for the young creator and A24. ## Who is in the cast of Backrooms? The eerie thriller features a stacked roster of award-winning talent. Lead actor Chiwetel Ejiofor brings major star power to the project, following his acclaimed roles in critical darlings like *12 Years a Slave* and *Dirty Pretty Things*. Starring alongside Ejiofor is Norwegian powerhouse Renate Reinsve. Reinsve gained international praise for her breakout lead role in *The Worst Person in the World* as well as her performance in *Sentimental Value*. Together, Ejiofor and Reinsve deliver compelling performances that elevate the internet-inspired lore into an undeniable cinematic event. Be sure to clear your streaming watchlist before September 25, because A24's record-smashing hit is coming home.
