A24‘s low-budget horror sensation Backrooms has officially crossed $400 million USD at the global box office. The indie hit directed by 20-year-old YouTuber Kane Parsons generated $197.5 million USD domestically and $202.57 million USD internationally, bringing its worldwide total to $400.09 million USD.

Produced for just $10 million, the film adapts Parsons’ viral web series centered on liminal spaces—eerie, seemingly infinite architecture originally popularized across 4chan, Reddit, and TikTok. Starring Chiwetel Ejiofor, Renate Reinsve, and Mark Duplass, the plot follows a furniture store operator who uncovers a sprawling maze of liminal rooms hidden beneath the store’s basement.

Driven by strong word-of-mouth and Gen Z audience turnout, Backrooms marks a historic milestone for A24, becoming the studio’s highest-grossing movie of all time by surpassing Marty Supreme ($192 million). The project also delivered A24’s largest opening weekend ever with an $81 million USD domestic launch, while making Parsons the youngest director in box office history to debut a film at No. 1.
