We don't usually cover horror on this site — it's a long way from Forks, Washington. But a $10 million movie that turned into one of the biggest box office stories of the year, built entirely out of an internet horror meme, is hard to ignore. So here's the rundown: what the Backrooms actually is, whether any of it is real, and whether it's worth your time before it lands on HBO Max.
Where "The Backrooms" Actually Came From
Long before A24 got involved, the Backrooms was just an image posted on the forum site 4chan back in 2019. It showed a plain, yellow-lit room with worn carpet and no clear purpose, and the caption warned that if you ever "noclipped" out of reality, this is where you'd end up — endless, empty, and not built for people to be in.
That single post turned into one of the internet's most durable pieces of collaborative horror fiction. Strangers online kept adding rules, "levels," and creatures to the idea over the next several years, the way ghost stories get added to around a campfire. In 2022, a teenager named Kane Parsons started posting short films on YouTube under the name Kane Pixels, using CGI to make the Backrooms look unnervingly real. Those videos are what eventually got him a directing deal with A24 — at 20 years old, for his very first feature film.
Is the Backrooms Movie Based on a True Story?
No — none of it happened. There's no research institute, no missing scientists, and no real dimension behind your local furniture store. The 1990s backstory the film builds around is invented specifically for the movie. The entire concept traces back to that one 2019 internet post, not to any documented event or place.
What Happens in the Movie
The film follows Clark, a furniture store owner going through a rough patch, who stumbles onto a door in his store's basement that shouldn't exist. What's behind it is a maze of identical, fluorescent-lit rooms that seem to stretch on forever. He brings people in to prove what he's found, and — this being a horror movie — that goes about as well as you'd expect.
Running alongside that is his therapist, who ends up searching for him and has her own baggage to deal with along the way. Without giving away where it lands, the film spends more time on dread and disorientation than on monsters jumping out at you.
Is the Backrooms Movie Actually Scary?
By most accounts, yes — but not in the "someone screams and you jump" way. The scares here come from wrongness rather than shock: rooms that look almost normal but aren't, silence that goes on a beat too long, hallways that shouldn't loop back on themselves but do. It's the kind of horror that's built to unsettle you slowly rather than startle you once and let you off the hook.
If you've ever gotten an uneasy feeling walking through an empty office building at night, or a mall after closing, that's basically the emotional register the whole movie lives in.

The film was written and directed by Kane Parsons, produced by A24 alongside James Wan's Atomic Monster, and filmed in Vancouver. It's rated R.
How Big of a Hit Is This, Really?
For context, that box office haul makes Backrooms the highest-grossing film A24 has ever released — beating out the studio's other well-known hits — on a budget that's a fraction of what most horror movies cost. It's also landed among the highest-grossing horror films of the year and among the biggest independent film successes ever, which is a wild outcome for a project that started as a teenager's YouTube hobby.
Wait, Is There a Backrooms Game Too?
Not officially, no — this A24 movie isn't a video game and isn't free to play. But because the Backrooms concept has been circulating online since 2019, plenty of independent, fan-made horror games and simulators based on the same idea already exist, made by completely different creators with no connection to this film. If you've played one of those, that's a separate thing from what you'd be watching here.
When Is Backrooms on HBO Max?
Backrooms starts streaming on HBO Max on September 25, 2026. It already had its theatrical run back in May, followed by a longer extended cut in July and a digital rental release shortly after — so this HBO Max date is really the first time it's been easy to watch without paying extra or hunting down a theater. It's an HBO Max exclusive — the film isn't and won't be on Netflix, since it's an A24 release and Netflix doesn't distribute A24's titles.
Is Backrooms Appropriate for Teens? The Age Rating, Explained
Backrooms carries an R rating from the MPAA, officially for "language and some violent content/bloody images." In practical terms: anyone under 17 needs to be with a parent or guardian to watch it legally in a US theater, and that R isn't a technicality — reviewers who cover family-viewing guidance consistently flag this one as sitting on the harder end of R, mostly because of how relentless the tension is rather than any single gory scene.
If you're trying to figure out whether it's okay for a young teenager specifically: most parental-guidance write-ups land on "not recommended" for anyone under 15 or so, less because of gore and more because the film is built to create sustained dread and a feeling of being trapped with no way out — the kind of thing that can genuinely sit badly with a younger or more anxious viewer well after the movie ends. There's minimal sexual content, so the concern here is almost entirely the psychological intensity plus frequent strong language, not anything else.
FAQ: The Backrooms Movie
Is the Backrooms movie scary?
It leans more into slow, sustained dread than jump scares. Critics generally praised it for building unease through sound design and empty, wrong-feeling spaces rather than relying on shock moments, so it's scary in a way that sits with you rather than startles you.
Is the Backrooms a real story?
No. The Backrooms started as a piece of internet fiction — a 2019 post on the forum site 4chan describing an unsettling empty room. It's not a real place or a documented event, just a very effective piece of collaborative internet horror.
Is Backrooms a free game?
The 2026 A24 film is not a game and isn't free — it's a paid theatrical release, now available digitally and soon on HBO Max. However, the Backrooms concept has inspired several free fan-made horror games and simulators that predate the movie and are unrelated to A24's production.
What makes the Backrooms so scary?
A lot of it comes down to how ordinary the setting looks. Instead of monsters or gore, the horror comes from familiar spaces — office corridors, carpeted rooms, fluorescent lighting — being just slightly wrong, with no exit and no explanation.
When does Backrooms come to HBO Max?
Backrooms begins streaming on HBO Max on September 25, 2026.
Is Backrooms based on a true story?
No. It's based on an internet urban legend, not real events. The film's 1990s research-institute backstory is entirely fictional, invented for the story rather than drawn from any real incident.
Is Backrooms on Netflix?
No — Backrooms is an A24 film, and Netflix doesn't distribute A24 titles. It's available to rent digitally now, and streams exclusively on HBO Max starting September 25, 2026.
Is Backrooms rated 17+? Can a 14-year-old watch it?
It's rated R, which technically means under-17s can watch with a parent or guardian present. In practice, most family-viewing guides recommend against it for anyone under about 15, mainly because of how psychologically intense and relentless the film is rather than its violence or language alone.
Is Kane Parsons 19, 20, or 21 years old?
All three numbers are technically correct depending on when you're asking. Parsons was born June 18, 2005. He turned 20 just weeks before Backrooms began filming in July 2025, was still 20 when the film released in May 2026, and turned 21 in June 2026 — which is his current age as of this writing.
Not our usual beat, but a $10 million YouTube-lore movie outgrossing most blockbusters this year earns a closer look. Watching it before or after it hits HBO Max?
