It started as one unsettling image on a 4chan thread and has grown into the most frightening cinema experience of 2026. Backrooms, directed by twenty-year-old Kane Parsons, has crushed box office expectations, terrified audiences around the world, and shown that the internet's darkest corners can produce superb horror. Made for just ten million dollars, the film has already earned more than one hundred eighteen million dollars globally in its opening weekend alone.

From 4chan to A24: The Origin Story
The Backrooms phenomenon began in 2019 on /x/, 4chan's paranormal board. An anonymous user posted a photo of an empty yellow room lit by buzzing fluorescent lights. The caption described a place you could "noclip out of reality" into, an endless stretch of monotonous, suffocating spaces. The image stuck in the internet's mind and spawned countless creepypasta tales, video games, and eventually Kane Parsons' YouTube series.
Parsons was just seventeen when he began posting his Backrooms videos. His found-footage approach, VHS look, and ambient score captured horror fans' imaginations, and his channel gathered millions of subscribers. The series became one of the platform's most successful independent horror projects.
A24 noticed. The studio behind arthouse horror landmarks like Hereditary and The Witch saw potential in Parsons' vision and gave him a ten million dollar budget. It also surrounded him with seasoned producers: James Wan, Shawn Levy, and Osgood Perkins. The result respects its internet roots while delivering a theatrical experience unlike anything else this year.

A Story That Feels Uncomfortably Real
The film follows Clark, played by Academy Award nominee Chiwetel Ejiofor, who runs a struggling furniture showroom in an unnamed 1990s town. His wife has left, he drinks heavily, and he sleeps in the store. His only outlet is therapy with Dr. Mary Kline, played by fellow Oscar nominee Renate Reinsve.
Then Clark finds something impossible: an invisible portal hidden in the basement wall, opening onto an endless maze of yellow rooms, buzzing lights, and suffocating silence. He starts exploring. He brings his employees and recording equipment. He becomes obsessed.
When Clark vanishes, Dr. Kline steps into the Backrooms herself. What follows is a slide into psychological terror that questions reality, memory, and the limits of human perception. The film declines to offer easy answers and leaves viewers with more questions than they came in with. That is exactly the point.
The Rules of the Backrooms
In the original creepypasta, you end up in the Backrooms when you "noclip out of reality." The levels are infinite, the silence is crushing, and something may be hunting you. Parsons' film follows these rules and never gives a concrete explanation for the phenomenon.
The trailer has drawn more than eighteen million YouTube views, with fans applauding how well it preserves the web series' VHS look and ambient score.
The Cast Anchoring the Nightmare
Chiwetel Ejiofor gives a career-defining performance as Clark. He is known for his dramatic range, but Backrooms asks for something different. Clark is no hero. He is a broken man weighed down by regret who stumbles into a horror he cannot grasp. Ejiofor makes him tragic, layered, and deeply unnerving.
Renate Reinsve brings her trademark vulnerability to Dr. Mary Kline, a therapist who has spent years helping others face their demons while ignoring her own. The Backrooms force her to confront everything she has buried, and Reinsve's performance grounds the film in real human emotion, lifting it above standard horror.
The supporting cast includes Mark Duplass as Phil, a mysterious figure who appears late in the film and whose place in the wider Backrooms mythology stays ambiguous. Finn Bennett plays Bobby, Clark's loyal employee; Lukita Maxwell is Kat, Bobby's girlfriend; and Avan Jogia plays Naren Warne, a researcher fixated on the Backrooms. The ensemble gives depth to a story that could easily have leaned only on atmosphere and jump scares.

A Box Office Phenomenon
Backrooms opened in North America on May 29, 2026, taking eighty-one point five million dollars domestically in its first weekend. The worldwide total hit one hundred eighteen million dollars, the biggest opening weekend ever for an original horror film.
That figure more than doubles A24's previous best domestic opening, and it makes twenty-year-old Kane Parsons the youngest director ever to debut at number one with a feature. For a first-time filmmaker working with a ten million dollar budget, the achievement is unprecedented.
The success is even more striking given the unconventional marketing. A24 leaned into mystery with cryptic trailers and minimal promotional material, and the approach paid off. Word of mouth has been fierce, and horror fans are calling it the scariest theatrical experience in years.

What the Critics Are Saying
Reviews have been overwhelmingly positive. The film sits at an eighty-six percent Certified Fresh rating on Rotten Tomatoes. Critics have applauded Parsons' direction, the work of Ejiofor and Reinsve, and the film's refusal to explain its central mystery.
Some critics did voice reservations about the conventional story structure. They feel the final act grows heavy-handed and over-explains details that would have worked better left ambiguous, and others say the third act brings in a character who seems forced into the mythology.
Most agree, though, that the film is at its best in its quiet, exploratory stretches. Scenes of characters wandering the yellow halls alone with their thoughts and the hum of fluorescent lights are where the horror hits hardest. Parsons' YouTube shorts background shows here; he knows exactly when to hold a shot and when to cut away.
"The fact that they are not only keeping the VHS aesthetic, but also the soundtrack from the webseries tells me this is going to be pure peak."

"I'm going to have nightmares for weeks, it's going to be awesome."

A Sequel Is Already in the Works
With such a huge hit, a sequel was a matter of when, not if. Kane Parsons has confirmed that he is already developing the next chapter and is looking for a writing partner to help expand the mythology. That suggests Will Soodik, the sole credited writer on the first film, will not be returning.
Parsons talked to Variety about his franchise plans. "For people who are into it, I've got a contract, and I got a hold at my end, and that means I am definitely not done with Backrooms," he said. "I've got very specific things that I'm working on, things are in the works right now that I am eager to be able to talk about, but currently, it's still in a secret mystery world".
As for where the story might go, Parsons has plenty of room to maneuver. The first film does not clearly set up a follow-up, but a character introduced at the end, played by Mark Duplass, could lead the next installment. Parsons seems uninterested in giving direct answers about the Backrooms, and the mystery remains the franchise's greatest strength.
The "Ghost Director" Conspiracy
Because Parsons is only twenty and had never directed a live-action feature, some conspiracy theorists have claimed that Backrooms was "ghost directed" by one of its big-name producers: James Wan, Shawn Levy, or Osgood Perkins.
Mark Duplass has publicly defended Parsons, saying he arrived on set extremely well prepared and needed no such help. "He's the real deal," Duplass said in an interview. "The kid knows exactly what he wants".
The Aesthetic That Defines a Generation
The film's most striking feature is its visual language. Parsons shot much of it on digital video processed to resemble 1990s VHS footage. The look is no gimmick; it is essential to the experience. The grain, tracking lines, and color shifts all add to a sense of unease running through every frame.
Jeremy Cox served as cinematographer and Danny Vermette handled production design. Together they built a world that feels familiar yet deeply wrong. The yellow wallpaper is slightly off, the carpet pattern is quietly disturbing, and the lighting is somehow too bright and too dim at once.
The score, composed by Parsons himself with Edo Van Breemen, is another highlight. It is made of ambient drones, distant echoes, and the occasional burst of static. The music never tells you how to feel. It simply exists, like the Backrooms themselves, waiting for something to happen.
Where to Watch
Backrooms is playing in theaters worldwide. A24 released it in North America on May 29, 2026, and various partners handle international distribution. The film is rated R for disturbing violent content, language, and some drug use, and runs one hour and fifty minutes.
A24 has not announced a streaming date. The studio normally keeps an exclusive theater window, and given the box office success that window could be extended. Early predictions point to digital availability in late July or early August 2026, with a likely streaming home on Max under A24's output deal with Warner Bros. Discovery.
