The Backrooms, A24‘s sci-fi psychological horror film, opens in theaters nationwide today—May 29, 2026. Directed by 19-year-old Kane Parsons, the film adapts his viral internet creepypasta and YouTube web series into a feature production that earned 84% approval on Rotten Tomatoes before its theatrical release. Starring Chiwetel Ejiofor and Renate Reinsve, the film explores a furniture store owner and his therapist who vanish into an alternate dimension—transforming internet folklore into a visually immersive cinematic experience.

From 4Chan Creepypasta to Hollywood Feature Film

The Backrooms originated as a 2019 internet horror story posted on 4chan describing an accidental “no-clip” into an alternate dimension of endless fluorescent-lit hallways and hums. The concept transformed into a semi-anthological YouTube web series that amassed millions of viewers through analog horror aesthetics and layered worldbuilding. Kane Parsons, then a teenager creating short films, expanded this internet lore into feature-length narratives, catching the attention of A24—the independent distributor known for backing auteur-driven genre films.

The leap from internet creepypasta to major theatrical release represents a significant moment in digital-to-cinema adaptation. Where previous internet-to-film conversions often failed, Backrooms retains the web series’ atmospheric foundation while leveraging A24‘s production scale and theatrical reach. The film’s existence validates internet folklore as legitimate source material for cinema.

Directorial Vision and Production Scope

Kane Parsons‘s achievement at age 19 marks him as A24‘s youngest-ever feature director. This distinction carries weight: his visual language from the YouTube web series translates directly to cinema, with none of the usual adaptation friction. Parsons directed, co-scored, and wrote the film’s narrative alongside screenwriter Will Soodik—maintaining creative control across multiple disciplines.

His debut feature represents a calculated risk that the studio clearly felt confident enough to greenlight. Director of Photography Jeremy Cox captured the unsettling fluorescent environment across 30,000 square feet of constructed set—a massive undertaking that grounds the alternate dimension in tactile, lived-in realism. Editor Greg Ng synthesized this footage into the rhythmic, psychological pacing that early reviewers highlighted.

Cast, Critical Reception, and Industry Validation

The ensemble cast elevates the project’s credibility. Chiwetel Ejiofor, an Academy Award nominee known for dramatic precision, anchors the narrative as Clark, the furniture store owner. Renate Reinsve, who earned international recognition through the film “Closest Feeling to Home,” portrays his therapist Mary. Supporting players Mark Duplass, Finn Bennett, and Lukita Maxwell fill key roles in a cast designed for character depth rather than celebrity drawing power.

Early critical response confirms Backrooms‘s thematic ambition. Rotten Tomatoes currently shows 84% Certified Fresh approval from 56 critic reviews—a score that positions the film as A24‘s strongest horror release in its theatrical window. IMDb ratings stand at 7.3/10 from initial audience reviews. The consensus points toward a psychological horror film that prioritizes atmosphere and dread over jump scares—aligning with contemporary prestige horror trends.

“Backrooms proves that not everything that comes from the internet and gets turned into a movie ends up being a terrible low-quality film. The movie stays committed to psychological atmospherics over sensationalism, using constructed sets and practical cinematography to create a sense of dislocation that haunts viewers long after the credits roll.”

— IMDb Critic Summary, Early Review Consensus

Why This Film Matters: The Prestige Horror Moment

Backrooms arrives during a critical moment for horror cinema. The genre has moved decisively away from pure spectacle toward introspection—films like A24‘s own Hereditary and Midsommar established that audiences reward atmospheric horror with philosophical depth. Backrooms follows this formula by anchoring its supernatural premise in psychological realism. Clark’s descent into an alternate dimension functions as both literal horror and metaphorical exploration of professional/personal dissolution.

The film’s cultural significance extends beyond its critical scores—it confirms that internet-native creators can transition to major studio productions without sacrificing authorial vision. Kane Parsons directed the web series that built Backrooms’ fanbase, then adapted that same creative sensibility to a $5M+ production budget. The continuity matters.

What Audiences Should Expect When Doors Open Today

Viewers walking into Backrooms tonight should prepare for sustained psychological unease rather than conventional horror beats. The 1 hour 45 minute runtime paces steadily toward escalation, with practical set design creating an oppressive sense of inescapable space. A24‘s theatrical presentation ensures that the film’s atmospheric sound design and color grading—core elements of the web series’ appeal—reach full impact on a cinema screen.

The R rating reflects language and intense imagery but not gore-heavy violence. This positioning signals an adult-targeted psychological horror rather than adolescent crowd-pleaser. Early audience reactions suggest Backrooms lands successfully with fans of the web series while introducing mainstream viewers to creepypasta-adjacent horror worldbuilding.

Can Internet Horror Go Mainstream Without Losing Its Soul?

The Backrooms Movie answers this question with unexpected success. The film retains the uncanny atmosphere that made Kane Parsons‘s YouTube videos compulsive viewing—that persistent sense that something is fundamentally wrong with the environment—while benefiting from professional cinematography, orchestral composition, and narrative structure. Whether audiences will embrace this vision nationwide throughout the weekend remains the real test. But early evidence suggests that A24 and Parsons have achieved something rare: an adaptation that respects its source material while achieving artistic growth.
