A24’s Backrooms has officially made horror movie history.
The viral horror adaptation opened to an astonishing $81.4 million domestically, setting a new record for the biggest opening weekend ever for an original horror film. The movie also earned approximately $118 million worldwide in its first weekend, instantly becoming one of the year’s biggest box office stories.
The achievement is especially remarkable because Backrooms began as a viral internet horror concept before evolving into a feature film. What was once an online nightmare about endless, empty hallways has now become a genuine theatrical phenomenon.
The film’s success also marks a major victory for A24, giving the studio one of the biggest openings in its history and proving that audiences are still eager to show up for original horror concepts when they capture the public’s imagination.
Perhaps the most surprising part is how quickly Backrooms transformed from internet curiosity into mainstream event cinema. Horror movies have delivered plenty of box office surprises over the years, but very few have arrived with this level of momentum.
For now, one thing is clear: Backrooms isn’t just a hit. It’s officially a record-breaker.
