The Backrooms box office record for A24 is now official: $81 million domestic and $118 million worldwide for the studio’s biggest opening weekend ever, shattering the $25.5 million debut held by Alex Garland’s “Civil War” since 2024. Director Kane Parsons is 20 years old. The budget was $10 million. The film was based on a found-footage YouTube short.
This is the kind of opening that rewrites how an entire studio greenlights movies for the next five years. It also confirms what A24 has been quietly testing all decade: that internet-native horror, marketed almost entirely through the same TikTok and YouTube ecosystem where its source material lives, can out-earn the traditional wide release. Here’s what actually happened, why it worked, and what it means for the rest of the 2026 box office.
The Backrooms box office record by the numbers
Friday alone brought in $38 million from 3,442 theaters — already past “Civil War’s” full opening weekend. Saturday and Sunday added another $43 million domestically, plus $37 million from international markets. Previews on Thursday night were $10.4 million, itself an A24 record before the official weekend even started.
The $81 million domestic figure is bigger than the opening weekends of every prior A24 release combined in the studio’s first decade. For a $10 million production, that is a 12x return in 72 hours, before the long tail of streaming, merchandise, and the inevitable sequel rights.
How a 20-year-old director broke the record
Kane Parsons uploaded the original “Backrooms” found-footage short to YouTube in 2022, when he was 16. It hit 50 million views in its first six months. A24 bought the rights in 2023 and — crucially — kept Parsons attached as director rather than handing the feature to an established filmmaker. He is now the youngest director ever to open a film at No. 1.
The film’s plot keeps the source material’s central conceit: a small-town furniture store owner (Chiwetel Ejiofor) discovers a portal in his showroom that opens onto the liminal, off-yellow, fluorescent-lit “backrooms” of the internet’s most viral horror universe. Renate Reinsve plays the psychologist trying to understand what’s happening to him; Mark Duplass rounds out the principal cast.
Why this is bigger than one weekend
Three things about the “Backrooms” opening matter for the industry. First, it validates A24’s bet on internet-native creators as feature directors rather than as IP licensors. Second, it proves that horror at the right budget can still command premium theatrical attention in 2026. Third, it suggests the studio’s marketing playbook — letting the fan community drive the conversation, with minimal traditional ad spend — scales further than anyone thought.
Compare to Lionsgate’s “Power Ballad,” the Nate Bargatze musical comedy that opened against it the same weekend. Despite a bigger marketing push and Bargatze’s strong stand-up following, the film opened to roughly $14 million — a respectable result that looks tiny next to “Backrooms” but would have been a perfectly fine A24 number a decade ago.
What this means for the rest of 2026
Expect every studio to spend the next six months looking for their own viral-horror IP. Expect the “Backrooms” sequel to be greenlit before the end of June, with Parsons attached and a 2027 release. And expect distributors to start paying more attention to TikTok and YouTube horror creators who have built large, loyal audiences without ever working in traditional film.
The 2026 summer box office now has its sleeper hit. The question is whether anything else — Marvel, Pixar, or the August horror slate — can match the cultural moment “Backrooms” just created.
Where to watch it
“Backrooms” is in wide theatrical release through at least Father’s Day weekend, with the streaming window expected to open on Max in late August. IMAX and Dolby Cinema screenings are already sold out at most major-market locations through next weekend; matinee and weekday evening shows are the easiest tickets to grab.
