From a $10 million indie horror to a $394 million global smash, Backrooms is finally streaming on HBO Max.

Backrooms has shattered expectations, pulling in $394 million worldwide and becoming A24’s highest‑grossing film ever—outpacing even Oscar‑nominated Marty Supreme. The low‑budget horror, produced for under $10 million, earned an 87% Certified Fresh rating on Rotten Tomatoes, proving that a creator‑driven vision can stand toe‑to‑toe with blockbuster franchises. The film expands the viral YouTube series that made Kane Parsons a household name among horror fans. It follows a beleaguered furniture store owner, Clark (Chiwetel Ejiofor), who uncovers a portal to an endless maze of liminal spaces beneath his shop. When he disappears, his therapist Mary (Renate Reinsve) ventures into the unsettling Backrooms to rescue him, navigating twisted corridors that warp reality itself. Supporting performances from Mark Duplass, Finn Bennett and Lukita Maxwell round out the psychological thriller, scripted by Will Soodik. After a theatrical run that defied every forecast, Backrooms will debut on HBO Max on September 25, just four months after its cinema launch. The streaming release promises to broaden its audience even further, cementing the movie’s status as one of the year’s most remarkable horror success stories and a testament to the power of online creators reshaping the genre.
The Best Horror Movie of 2026 Officially Scores a Major Sequel Update

Backrooms 2 is gearing up with its original creator at the helm—A24 may be about to unleash the sequel to the $400 million internet‑origin horror hit.

Kane Parsons, the YouTube‑born auteur who turned the viral “no‑clip” myth into the 2026 blockbuster Backrooms, is reportedly set to direct its long‑awaited sequel for A24. While the studio hasn’t issued a formal announcement, Dread Central says Parsons has officially signed on, hinting that the next chapter will finally tackle the dangling threads left by the first film—namely the fate of Mary (Renate Reinsve), the enigmatic Async phenomenon, and the ever‑expanding maze of hidden entrances. The original Backrooms was a shoestring $10 million production that exploded into a global box‑office juggernaut, pulling in roughly $394 million worldwide. Its success proved that a concept born from a simple video‑game glitch and a sprawling internet meme could translate into mainstream horror gold. Parsons has long described the first movie as merely a “doorway” into the deeper mythology he’s been building since his zero‑budget YouTube shorts. Parsons says he wants the sequel to remain “accessible” while still serving as a true entry point for newcomers, a delicate balance given the lack of a single canonical angle on the Backrooms lore. Fans can expect the sequel to weave together the fragmented narrative strands while preserving the unsettling, labyrinthine atmosphere that made the original a cultural phenomenon. Until an official press release lands, the news should be taken with a grain of salt—but if the reports hold true, Backrooms 2 could cement the franchise’s place as one of the most lucrative horror adaptations of internet culture, and A24’s involvement suggests a stylistic upgrade that could push the series even further into the mainstream.
