Kane Parsons turns Backrooms into A24's box-office horror hit

Director Kane Parsons has done the thing a lot of internet-native creators dream about and very few actually pull off: he moved Backrooms from a web series into a full A24 movie. That matters because the project did not start as some polished studio franchise with a giant marketing machine behind it. It started in 2022, when Parsons launched an independently made web series that expanded on a creepypasta already popular with the chronically online. Now, in 2026, that same idea is not just on the big screen, it is gathering well-earned rave reviews and ruling the box office.

That is the headline, and the business case is sitting right underneath it. Backrooms did not arrive as a random IP grab. It had a preexisting audience, a recognizable internet mythos, and enough cultural momentum to justify the leap from screen share to theater seats. For A24, the result is a reminder that the path from niche digital obsession to mainstream revenue can run through horror, a genre that has long punched above its weight when it comes to converting low-friction curiosity into paid admissions. For everyone else watching the entertainment market, this is a clean example of how online-native storytelling can graduate into a premium theatrical event when the audience already understands the premise.

The source says the film is based on a creepypasta, which is internet folklore built around user-generated horror stories that spread and mutate online. That background matters because it helps explain why Backrooms had a built-in starting point before the movie existed. Parsons did not have to teach people the world from zero. He expanded it. The original web series, launched in 2022, acted like a proof of concept, showing that the idea had enough texture and mystery to sustain longer-form attention. In practical terms, that is the kind of early signal studios and investors love: not just clicks, but repeat engagement around a recognizable concept.

The move from independently made web series to A24 release also shows how the economics of attention are changing. Historically, studio-backed films had the loudest distribution channels. But internet-born projects can now build a different kind of leverage first: community. If the audience is already talking, remixing, and showing up for the property before the studio spend arrives, the risk profile changes. You are no longer betting purely on awareness. You are betting on conversion. Backrooms appears to have made that leap, and the current box office performance suggests that the audience did not disappear when the format changed. It followed the story.

For executives, the strategic lesson is not that every web series deserves a theatrical release. Most do not. The lesson is that origin matters less than momentum, and momentum is easiest to spot when a concept carries a distinct world, a strong hook, and enough mystery to keep people leaning in. Backrooms had all three: a cult internet foundation, a filmmaker who launched it independently in 2022, and a major studio partner in A24 once the idea had already proven it could travel. That sequence is increasingly important in a media market where discovery is fragmented and attention is expensive. Build the audience first, and the distribution conversation gets easier.

There is also a broader signal here for creators, studios, and anyone sitting on the fence about where the next durable IP pipeline comes from. The old model assumed the studio found the idea, financed it, marketed it, and then hoped the public cared. The Backrooms arc flips that order. The public cared first. Parsons took that signal and scaled it. A24 then backed a version of the property that was already carrying its own mythology. The result, according to the source, is a film now earning rave reviews and dominating the box office, which is exactly the kind of outcome that makes competitors start looking harder at their own development slates.

For peers in entertainment, gaming, publishing, and any business chasing fandom as a moat, the implication is simple: internet-born worlds can become real assets if they survive the jump from inside joke to shared experience. Backrooms did that by staying weird, staying recognizable, and giving audiences something they already wanted to inhabit. That does not mean the market will suddenly be flooded with winners. It does mean the playbook is evolving. The next breakout may not come from a boardroom pitch deck. It may come from a creator with a camera, a cult audience, and enough narrative gravity to make a studio pay attention.
