Almost everyone seems to have been noclipped into the Backrooms since its release, as the new wave of YouTubers-turned-directors continues proving it belongs on the big screen. Adapted from the viral creepypasta, A24's Backrooms opened to an enormous $118 million worldwide, setting a new record for an original horror film. The breakout success also made 20-year-old Kane Parsons the youngest filmmaker ever to top the global box office. For most movies, that would be achievement enough.

Instead, the horror phenomenon has kept adding milestones, with its latest feat pushing it ahead of the Oscar-nominated Marty Supreme in the process.

For a film about getting lost in endless hallways, Backrooms seems remarkably good at finding milestones. According to The Hollywood Reporter's latest weekend box office chart, Kane Parsons' horror sensation has officially overtaken Timothée Chalamet's Marty Supreme to become A24's highest-grossing movie worldwide. The internet-born phenomenon now stands at $212 million globally, moving comfortably past the sports dramedy's $191.3 million finish.

What makes the achievement particularly striking is the calendar. Backrooms only arrived in theaters on May 29, meaning it claimed A24's all-time crown in just its second weekend of release. While many films spend months chasing such numbers, Parsons' fluorescent nightmare reached the summit before most blockbusters have even settled into their theatrical run.

It seems that impressive speed was not only reserved for breaking that one particular record. The breakout horror hit crossed the $100 million domestic mark in only six days, making it the fastest A24 release ever to reach that benchmark. For a studio known for cultivating slow-burn successes, Backrooms, whose part 2 is already in development, is behaving less like a sleeper hit and more like a sprint.

Yet, box office records are not the only thing that Backrooms is breaking as it dismantles the way horror movies have been looked at for years.

Beyond the box office numbers, Backrooms is quietly reshaping how Hollywood thinks about horror itself. Kane Parsons proved that an endless maze of yellow walls, oppressive silence, and psychological unease can captivate audiences just as effectively as masked killers or elaborate supernatural mythology. The film places atmosphere ahead of spectacle, suggesting that modern viewers increasingly fear uncertainty, isolation, and the unfamiliar rather than traditional genre villains.

The ripple effects extend far beyond a single hit movie. By transforming internet folklore into a global theatrical phenomenon, Parsons has also challenged long-standing assumptions about who gets to define mainstream horror. As marty continues collecting milestones and surpassing films such as Marty Supreme, its greatest achievement may be convincing Hollywood that the future of blockbuster horror is already hiding in the corners of the internet.
