What Does the New Teaser for A24’s Backrooms Reveal?
The first teaser trailer for Backrooms has finally arrived, giving fans their first glimpse at the big-screen adaptation of one of the internet’s most unsettling horror concepts.
The short preview leans heavily into atmosphere rather than plot. Viewers are guided through a series of eerily empty rooms — endless hallways filled with yellow wallpaper, damp carpet, and flickering fluorescent lights. A voiceover from Chiwetel Ejiofor hints at the mysterious dimension at the heart of the story: “I found a place… it just goes on and on and on.”
The footage captures the strange, claustrophobic feeling that made the original Backrooms concept so unsettling online, suggesting that A24 is leaning fully into the surreal dread of the myth.
What Is Backrooms About?
The film expands on the internet legend of the Backrooms — a mysterious alternate dimension made up of endless, maze-like rooms that seem to exist outside normal reality.
According to the official premise, the story begins when a strange doorway appears in the basement of a furniture showroom. After someone disappears into the bizarre dimension beyond that doorway, a therapist ventures inside the Backrooms to try to bring them back alive.
The deeper they go, the more unsettling the environment becomes. The Backrooms are often described as an infinite network of empty office-like spaces filled with buzzing lights, repeating architecture, and the constant sense that something else may be lurking in the maze.
It’s a concept that blends psychological horror with existential dread — less about jump scares and more about the terrifying idea of getting lost in a reality that never ends.
Why Is This Movie Such a Big Deal for Internet Horror?
What makes Backrooms unique is its origin story.
The concept first appeared as a creepypasta on the imageboard 4chan in 2019, where users imagined a hidden dimension accessible by “no-clipping” out of reality.
The idea exploded in popularity after filmmaker Kane Parsons released a short film titled The Backrooms (Found Footage) on YouTube. The eerie video, created largely with CGI, racked up tens of millions of views and launched a full series expanding the mythos.
Now Parsons — who started the project as a teenager — is making his feature-film debut directing the official movie adaptation for A24, making him one of the studio’s youngest directors ever.
Who Stars in Backrooms?
The film pairs its viral horror concept with a surprisingly stacked cast.
Alongside Ejiofor, the movie stars Renate Reinsve, best known for her breakout performance in The Worst Person in the World. The ensemble also includes Mark Duplass, Finn Bennett, Lukita Maxwell, and Avan Jogia.
Behind the scenes, the project also carries major horror pedigree with producers like James Wan, whose company Atomic Monster is helping bring the film to life.
When Will Backrooms Release?
Fans won’t have to wander the infinite hallways too long.
Backrooms is scheduled to arrive in theaters on May 29, 2026, marking one of the most anticipated horror releases of the year.
Given A24’s reputation for genre-defining horror — from Hereditary to Talk to Me — expectations are already sky-high for how the studio will translate an internet phenomenon into a full cinematic nightmare.
Could Backrooms Become the Next Internet-Born Horror Hit?
The journey from creepypasta to blockbuster horror movie is still relatively new territory, but Backrooms might be the perfect candidate to make it work.
The concept already lives rent-free in the minds of millions of internet users who grew up exploring eerie liminal-space videos and Backrooms games. Now, with A24’s production muscle and a filmmaker who helped create the myth in the first place, the story is getting its biggest stage yet.
And if the teaser’s unsettling vibe is any indication, audiences may soon discover that the Backrooms aren’t just an internet legend anymore — they’re a place you’ll be able to get lost in on the big screen.
