Backrooms continue to prove that original horror can still draw huge crowds. According to The Hollywood Reporter, the A24 film has now earned more than $350 million worldwide, reaching another impressive milestone during its theatrical run. What started as an ambitious adaptation of Kane Parsons’ viral YouTube series has grown into one of the biggest box office success stories of 2026.
Made for a reported budget of around $10 million, the film has far exceeded expectations. The Hollywood Reporter notes that Backrooms has become A24’s highest-grossing movie ever, giving the independent studio one of the biggest financial wins in its history. The film’s success has been driven by strong word of mouth, with audiences praising its eerie atmosphere and unique take on internet horror.
Directed by Kane Parsons, who was just 20 years old when the movie was released, Backrooms expanded on the online phenomenon that first made him famous. The film stars Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, and Lukita Maxwell, blending psychological horror with the unsettling mystery that made the original videos so popular. Instead of relying on familiar jump scares, the movie builds tension through its endless maze of empty hallways and growing sense of isolation.
Crossing the $350 million mark is another sign that audiences are still eager for fresh ideas on the big screen. With Backrooms continuing to perform well around the world, the film has not only become A24’s biggest hit but has also established Kane Parsons as one of Hollywood’s most promising new filmmakers.
