Backrooms has quickly become one of the biggest movies of 2026. Based on director Kane Parsons’ hit web series, itself inspired by a viral internet creepypasta, the film earned over $360 million at the global box office on a $10 million production budget. Thanks to such glowing reviews and a loyal fanbase, this A24 horror movie has become the indie studio’s highest-grossing movie. This success not only led to A24 re-releasing the movie with 20 minutes of bonus footage, but it also sparked widespread discussion about the rise of YouTube-born filmmakers in Hollywood.
