Backrooms Obliterates A24 Opening Record With $38 Million Friday, Eyes $90 Million Weekend

Horror audiences turned out in force for Backrooms this weekend, as the film's opening day numbers have already rewritten the record books at A24.

The movie brought in $38 million on Friday, May 29, with Thursday night previews contributing $10.4 million to that total. That single day of earnings has already surpassed A24's previous opening weekend record of $25.5 million, which was set by Civil War in 2024.

Directed by 20-year-old Kane Parsons—who helmed the project at just 19 years old—Backrooms centers on a mysterious doorway that materializes in a furniture showroom's basement, opening into a bewildering labyrinth of interconnected rooms. The ensemble cast includes Chiwetel Ejiofor, Renate Reinsve, Mark Duplass, Finn Bennett, and Lukita Maxwell.

The film adapts Parsons' viral YouTube series of the same name, which built a devoted following around its exploration of unsettling liminal space horror. That online fanbase appears to have translated into significant theatrical momentum.

Projections currently estimate the film will land between $85 million and $90 million for the full weekend. Should those numbers hold, Backrooms would surpass A24's all-time domestic box office record of $96 million, held by Marty Supreme, within its first four or five days in theaters.

The strong debut positions Backrooms as a major commercial success for the distributor and signals robust audience appetite for the horror genre.
