A24's Backrooms Movie Breaks Box Office Records With $85M Opening Weekend Driven by Internet Fandom

A24's Backrooms has shattered the studio's box office records with an opening weekend between $85 million and $89 million, a figure that exceeds multiple established franchises and marks a significant victory for internet-sourced intellectual property adapted to film. The atmospheric horror film, directed by 20-year-old YouTuber Kane Parsons, achieved a first-day total of $38.4 million and is generating strong repeat viewership despite mixed critical reception.

Box Office Performance Defies Expectations

The film's opening weekend surpasses the recent Star Wars entry The Mandalorian and Grogu, which earned $81.6 million domestically with backing from Disney's near-$100 million marketing campaign. Backrooms achieved its success through a significantly leaner approach—a laser-focused, curated marketing strategy that prioritized direct engagement with existing internet communities rather than broad mass-market promotion. Some industry analysts project the worldwide opening could reach between $121 million and $124 million, with an estimated $36 million from offshore territories including the United Kingdom, Italy, Australia, Mexico, Brazil, South Korea, and Saudi Arabia.

The film's strongest demographic performance centers on women under 25, comprising 24 percent of audiences with 72 percent positive ratings in PostTrak exit surveys. Audience composition reflects significant diversity, with 38 percent Caucasian, 33 percent Latino and Hispanic, 13 percent Black, and 10 percent Asian American attendees. The highest-grossing single venue was AMC Burbank in Los Angeles, which generated $93,000 in ticket sales.

From Internet Mythology to Cinema

The Backrooms originated as an anonymous 4chan creepypasta post featuring a 2002 photograph from a Wisconsin furniture store. The original caption describing the "Backrooms"—a sprawling dimension of endless yellow-wallpapered rooms with the "stink of old moist carpet" and fluorescent hum—became foundational internet lore. Parsons transformed this creepypasta into a YouTube phenomenon, debuting "The Backrooms (Found Footage)" in 2022 as the first entry in a series of analog horror shorts that expanded the urban legend into an elaborate narrative involving a fictional research institute called Async.

The film stars Chiwetel Ejiofor as Clark, a failed architect and furniture store owner who discovers a mysterious portal in his warehouse basement. Alongside Lukita Maxwell as Kat, Finn Bennett as Bobby, and Renate Reinsve as therapist Dr. Mary Kline, Clark becomes obsessed with exploring the nightmarish liminal dimension, dragging others deeper into its unsettling labyrinth. The narrative evolves from slow-burn atmospheric dread to cosmic horror, grounded in years of accumulated internet mythology.

Audience Reception and Repeat Viewership

Despite a CinemaScore rating of B-, the film demonstrates unusual repeat-viewing patterns among its core fanbase. At the Aero Los Angeles premiere, attendees reported seeing the film multiple times before its wide release, reflecting the intensity of devotion within Backrooms communities. PostTrak data shows 53 percent of audiences provided definite recommendations, with 68 percent overall positive sentiment and three-star ratings—indicating strong word-of-mouth potential despite the moderate critical score.
