Backrooms Movie (2026): Review, Ending Explained & Everything You Need to Know

The internet's most unsettling urban legend has officially made it to the big screen. Backrooms, directed by 20-year-old YouTube phenomenon Kane Parsons and distributed by A24, opened in theaters on May 29, 2026 — and critics are already calling it one of the most unnerving horror debuts in years. Whether you're a longtime fan of the original creepypasta, a binge-watcher of Parsons' viral YouTube series, or simply chasing the next great A24 scare, this guide covers everything: the plot, the cast, the Rotten Tomatoes score, the ending, and the burning question — does Backrooms have a post-credits scene?

What Is the Backrooms Movie? (Plot Overview)

The story follows Clark (Chiwetel Ejiofor), a furniture store owner who discovers a mysterious doorway hidden in his basement. That doorway leads to the Backrooms — an infinite, maze-like dimension of windowless rooms, off-yellow carpeted corridors, and humming fluorescent lights with no apparent exit. The space isn't just disorienting; it feeds on its visitors' deepest psychological fears, warping their perception of reality the longer they stay inside.

When Clark vanishes into the maze, his therapist Dr. Mary (Renate Reinsve) descends into the Backrooms to find him. What follows is a cat-and-mouse survival thriller wrapped in surreal, liminal horror — with layers of lore tied to a shadowy research organization called Async, which has been secretly studying the Backrooms for decades.

The supporting cast includes Mark Duplass as Phil, a high-ranking Async researcher with a mysterious past; Finn Bennett and Lukita Maxwell as Clark's younger employees who meet grim fates inside the maze; and Avan Jogia rounding out the ensemble.

Who Is Kane Parsons? The Youngest A24 Director Ever

If you're new to the name, here's why it matters. Kane Parsons — known online as Kane Pixels — began uploading his Backrooms found-footage YouTube series in January 2022, when he was just 16 years old. The series became a viral phenomenon, racking up tens of millions of views with its eerily realistic depiction of liminal spaces and analog horror aesthetics.

A24 tapped Parsons to direct the feature adaptation when he was only 17, making him the youngest director ever commissioned by A24. During the film's development, he was mentored by horror heavyweights James Wan (Saw, The Conjuring) and Osgood Perkins (Longlegs), who served as executive producers alongside Shawn Levy.

Filming took place in Vancouver, Canada from July 7 to August 14, 2025 — a remarkably fast shoot for a major theatrical release. The practical production design, including custom set builds modeled in Blender by Parsons himself, gives the film a handcrafted weight that separates it from most studio horror.

Backrooms Rotten Tomatoes Score (2026)

As of its opening weekend, Backrooms holds an 87% critics score on Rotten Tomatoes — a strong certified fresh rating that puts it comfortably among A24's best-reviewed horror titles. Box office analysts project the film could earn over $40 million in its opening weekend, potentially setting a new record for the biggest A24 opening ever.

Here's a snapshot of what critics are saying:

• "The opening seven minutes are among the most effective horror filmmaking of the year." — The AU Review
• "There is a second-act sequence that will likely stand as one of the most bone-chilling things you'll see in a theater in all of 2026." — Discussing Film
• "When Backrooms works, it's an arresting triumph and one of the strongest debut features in years." — In Review Online
• "Deeply unnerving. Haunting, leaving behind lingering shivers and ongoing anxieties." — Rotten Tomatoes Critic

Not every review is a rave — some critics feel the screenplay, written by Will Soodik, plays things a little too safe and restrained for a concept this wildly imaginative. But the consensus is clear: Parsons is a generational talent, and Backrooms delivers the goods for fans of A24's brand of elevated horror.

Backrooms Movie Review — Is It Worth Watching?

Backrooms is best described as what might happen if The Blair Witch Project crashed into Alex Garland's Annihilation — found-footage claustrophobia colliding with mind-bending, other-dimensional dread. The film opens with a breathtaking cold open: a shaky VHS camcorder racing through endless yellow-carpeted corridors, building unbearable tension before a perfectly placed jumpscare kicks the story into gear.

What Works

• The atmosphere is immaculate. Cinematographer Jeremy Cox frames the liminal spaces with a clinical precision that makes every hallway feel genuinely infinite. The set design — much of it conceived by Parsons in Blender — is stunning for any budget.
• The performances anchor the surreal premise. Chiwetel Ejiofor brings a crumbling, manic energy to Clark, while Renate Reinsve (known internationally for The Worst Person in the World) proves she's equally compelling as a horror lead.
• There is at least one set piece that will become legendary. The second-act sequence critics keep alluding to (without spoilers) is genuinely among the best horror filmmaking of the decade.
• It respects the source material without being enslaved by it. Parsons is clear that his film is "a Backrooms story, not the official one" — giving newcomers a clean entry point while rewarding fans of the web series with deep-cut Async lore.

Where It Falls Short

• The script's midpoint character turn is abrupt, and some emotional beats feel underbaked compared to the visual craft surrounding them.
• For a concept this boundary-pushing, the narrative stays within fairly familiar A24 horror conventions. Viewers hoping for total chaos may leave wanting more.

Verdict: A remarkably assured debut from one of the most exciting young directors in Hollywood. If you enjoy A24 horror — think Hereditary, Midsommar, or Talk to Me — Backrooms absolutely belongs on your list.

Backrooms Ending Explained

⚠️ Spoilers below. Read at your own risk.

The film's conclusion leaves several threads deliberately unresolved — consistent with the open-source, ambiguous nature of the Backrooms mythology. Here's what we know:

Clark, consumed by his obsession with the Backrooms, ultimately chooses to remain inside the maze rather than return to the real world. After leading his two employees into the dimension — where both meet violent ends — Clark accepts the Backrooms as his new home. The film frames this as a tragic but almost inevitable surrender: the longer someone remains inside, the less they are able (or willing) to leave.

Dr. Mary's journey into the maze to find Clark serves as the emotional spine of the film. Her arc traces a shift from clinical detachment to raw, primal survival — and Reinsve plays every stage of that transformation with complete conviction. Whether Mary successfully escapes is left open to interpretation, in classic A24 fashion.

Who Is Phil — and What Is Async?

Mark Duplass plays Phil, a senior Async Research Institute operative who interrogates characters throughout the film. Fans of the YouTube series will recognize the nod: in the episode "Prototype," a researcher named Philip R. Heymann conducted the original 1982 experiment with the Low-Proximity Magnetic Distortion System — the device Async used to first breach the Backrooms. The film strongly implies that Duplass's Phil is this same character, now decades older and still working within the organization.

Async itself is never fully explained in the film, operating as a sinister, institutional shadow — giving the story room for future entries in what could become a franchise.

What Do the Backrooms Actually Mean?

Parsons, speaking at CCXP Mexico in April 2026, described the Backrooms as a space that exploits the human brain's instinct for spatial mapping. Unlike other interpretations, the rooms in his vision don't randomly shift or change: "If you go back the way you came, you will go back the way you came — but it just keeps going and going and going. That's where the confusion is. Eventually, you just have to give up trying to map it." The horror isn't that the maze is supernatural randomness — it's that it is infinite order that the human mind simply cannot process.

Does Backrooms Have a Post-Credits Scene?

No — Backrooms does not have a post-credits scene. There is no mid-credits scene, no post-credits scene, and no bonus footage of any kind after the movie ends. Everything the film has to say is said before the credits roll.

You are completely safe to leave the theater as soon as the credits begin. No need to sit through the full roll waiting for a tease.

Final Thoughts

Backrooms is a remarkable achievement for a first-time feature director — let alone one who is only 20 years old. Kane Parsons has taken an internet phenomenon built on ambiguity, dread, and communal storytelling and channeled it into a proper theatrical event. It won't satisfy everyone: the script occasionally struggles to match the stunning visual craft surrounding it, and the story's restraint may frustrate viewers who wanted something wilder.

But for fans of A24 horror, liminal-space mythology, or simply anyone who wants to be genuinely unsettled for 105 minutes, Backrooms is essential viewing in 2026. Remember the first horror movie that changed the way you thought about space, darkness, and the unknown? For a lot of people, this is going to be that movie.
