Backrooms is already getting a re-release with 15 minutes of bonus footage.
The surprise horror blockbuster from YouTuber Kane Parsons has been a huge hit at the box office, making more then $330 million worldwide after being produced for just $10m.
Now, an AMC listing has confirmed a July 4 weekend re-release titled Backrooms: Everything Must Go Edition.
The cinema chain has described the screening as including a "theatrically exclusive post-credit" featuring additional footage from Parsons.
In the UK, the Cineworld listing teases: "New version of the film featuring 15 minutes of bonus footage after the end credits.
"Get more insight into one of the most scariest and enjoyable films of 2026."
The new version will run for 2 hours and 6 minutes.
The movie stars Chiwetel Ejiofor as a furniture store boss who finds an endless world of liminal spaces behind a wall in the store's basement.
The cast also includes Renate Reinsve as his therapist Dr. Mary Kline, as well as the likes of Mark Duplass (Phil), Finn Bennett (Bobby Franklin) and Lukita Maxwell (Kat Taylor).
Backrooms was inspired by the online creepypasta of the same name, which sparked Parsons' The BAckrooms web series on YouTube.
The 20-year-old director has confirmed there will be more to come in the future, although he's not given firm details for his plans.
He told Rolling Stone magazine: "I think this is a world-building exercise on top of what I’ve already done.
"I’m well into it, and plan on certainly continuing it. Backrooms is not done!"
Backrooms isn't the only surprise horror hit this year, after Curry Barker's Obsession also stormed the box office.
The film was made by the 26-year-old YouTuber, for just $750,000, and it grossed $334 million over its first 39 days.
Horror pioneer Jason Blum recently praised the work of the two young content creators.
Speaking at the Produced by Conference on the Universal Lot in Los Angeles, he said: “They’re made by non-traditional directors, directors who really honed their skills as creators online.
"Their hope and desire and dream is to make cool movies. Backrooms and Obsession are edgy and weird and f******nuts.
"And to me, there’s almost this feeling of the ’70s, of a new generation of young people making edgy movies that are connecting in theaters in a crazy way.
"So many young people grew up in a time when they couldn’t go to the movies, and they haven’t had something made for them that gets them off their iPad and into theatres. Suddenly they have two movies.”
