A24 dropped the official trailer for “Backrooms” on March 31 — a feature film adaptation of Kane Parsons' viral YouTube horror series, itself based on the creepypasta phenomenon that started as a single 4chan post in 2019. Parsons, now 20, is A24's youngest-ever director. The film stars Chiwetel Ejiofor and Renate Reinsve, with James Wan, Shawn Levy, and Osgood Perkins producing. It opens May 29. Here's the trailer:

1. A24 Knew Exactly What They Were Doing (Horror Fans, A24 Loyalists, Parsons' YouTube Community)

The kid who made 190 million people watch fluorescent-lit hallways on YouTube just got the keys to a real movie. And the trailer looks like he kept the keys.

Parsons isn't a hired gun — he built this world from scratch. He was 16 when his nine-minute found-footage short went from 1 million to 7 million views in 48 hours. His YouTube series has since amassed over 190 million views. A24 signed him at 19, and by all accounts gave him room to work — Parsons told Dazed the studio let him expand without much interference.

The producer lineup is a statement. James Wan (Conjuring, Saw), Shawn Levy (Stranger Things), Osgood Perkins (Longlegs) — these aren't people who sign onto internet curiosities. They sign onto movies they think will work. Ejiofor and Reinsve are both Oscar nominees. This has the talent infrastructure of a prestige horror film, not a meme adaptation.

The fans already trust it. A24's marketing is leaning into the community — posters reference the original 4chan post, different hues of yellow nod to the Backrooms' different "levels." The trailer hit 23,000 views in under five minutes. The built-in audience is massive and engaged.

2. We've Seen This Movie Before — Literally (Skeptics, Slender Man Survivors, Den of Geek)

The last time a studio turned a creepypasta into a movie, we got Slender Man. It has an 8% on Rotten Tomatoes.

Creepypasta adaptations have a terrible track record. The 2018 Slender Man film is the cautionary tale — it reduced an internet horror phenomenon to generic jump scares and earned an 8% on Rotten Tomatoes. Boing Boing's Rob Beschizza predicted years ago that the Backrooms would become a "slick but dismal 2-hour Hollywood movie." Critics at League of Filmmakers note that creepypasta properties have a long history of losing their power when translated into traditional narrative formats.

The Backrooms works BECAUSE it's formless. The original 4chan post was a single image and a few sentences. Parsons' YouTube series works as found footage — shaky cameras, no dialogue, pure atmosphere. The trailer shows actual characters with dialogue and a conventional narrative structure. The worry is that what made the Backrooms terrifying — the absence of explanation, the pure liminality — gets sacrificed the moment you add a plot and a reason to go into the maze.

A 20-year-old first-time director is a gamble. Parsons has never directed actors, never managed a full crew, never told a story longer than nine minutes. YouTube filmmaking and feature filmmaking are different disciplines. A24 is betting that the vision translates. That bet has failed before.

3. This Is the Future of Hollywood (Industry Analysts, No Film School, YouTube-to-Film Pipeline Watchers)

A YouTuber's first movie got two Oscar nominees and James Wan. The pipeline from internet to cinema just got a lane upgrade.

Iron Lung proved the model. Markiplier's self-distributed internet horror film crossed $52 million worldwide earlier this year. That was without a major studio, without Oscar-caliber actors, without James Wan producing. The Backrooms has all of that plus A24's distribution muscle. If this works, it redefines what "development" means — studios won't need to develop IP when the internet is generating it for free.

Parsons represents a generational shift. He's 20. He grew up making horror on YouTube. He didn't go through film school or the indie festival circuit — he went through the algorithm. A24 recognized that his 190 million views represented something studios spend tens of millions trying to build: a pre-existing audience that already loves the world. One industry analyst predicts this could be the biggest hit A24 has ever produced.

The risk is real but asymmetric. The downside is a Slender Man repeat. The upside is a new franchise, a new director pipeline, and proof that internet-native storytelling is the future of horror IP. A24 has bet on weird before — "Everything Everywhere All at Once" made $140 million. The Backrooms has a bigger built-in audience than that film ever did.

Where This Lands

The Backrooms trailer is a test of whether internet horror can survive first contact with Hollywood. Parsons' YouTube series proved the concept — 190 million views don't lie. But every creepypasta adaptation before this one has failed, and the step from formless internet dread to structured feature film is where the magic usually dies. If A24 and Parsons pull it off, the Backrooms becomes the template for a new kind of movie — born online, raised on YouTube, finished in theaters. If they don't, it joins Slender Man in the graveyard of internet horror that couldn't make the jump. May 29 is the answer.
