How a 20-Year-Old YouTuber Just Made A24's Biggest Horror Hit of 2026

From YouTube Creepypasta to Box Office Domination

If you haven't heard about Backrooms by now, where have you been hiding? The A24 horror film — directed by none other than 20-year-old YouTube phenom Kane Parsons — just pulled off something that most veteran directors can only dream of: it hit No. 1 at the domestic box office with an $81 million opening weekend on a paltry $10 million production budget.

That's right. A kid who grew up making creepy liminal space videos on YouTube just became the youngest filmmaker ever to top the box office. Let that sink in.

What Makes Backrooms So Special?

The film is based on the viral internet horror concept known as the "Backrooms" — those endless, unsettling, fluorescent-lit hallways that feel like a bad office memory you never actually had. The creepypasta blew up across YouTube, Reddit, and TikTok, and Parsons was one of the original creators who gave it visual life with his highly cinematic short films.

A24 saw the potential and handed the reins back to Parsons himself. The result? A deeply unsettling psychological horror that stars Oscar-nominated Chiwetel Ejiofor as a furniture shop owner who stumbles into a nightmare of liminal spaces, alongside Renate Reinsve (who you might remember from The Worst Person in the World).

Critics have been divided — which is honestly the most A24 reaction possible. Some call it "distinctive" and "exceptionally creepy," while others say it gets "trapped in its own maze." But audiences? They showed up in droves. Gen Z packed theaters, and Cinemark reported its biggest-ever domestic box office month thanks largely to this film.

Box Office Numbers That Tell the Story

Here's what the numbers look like after just its first weekend:

Domestic opening weekend: $81 million
Global total (so far): $118 million
Production budget: $10 million
A24 record: Broke the studio's opening record in the U.K. and Ireland

For comparison, Backrooms outgrossed almost every other 2026 horror film in just three days. Meanwhile, fellow horror hit Obsession is sitting at $148M globally, and Michael is nearing $900M worldwide — but those are from established studios with massive marketing machines. Parsons? He started with a YouTube channel and a concept.

What's Next: Backrooms 2 Is Already in the Works

Here's the cherry on top — Forbes confirmed that Kane Parsons has already teased a Backrooms 2. With numbers like these, a sequel was never really in doubt, but Parsons also hinted at returning to his YouTube roots with new original horror content. The kid is only getting started.

Whether you're a horror fan, an A24 loyalist, or just someone who finds endless yellow hallways genuinely terrifying, Backrooms is proof that the internet can still produce real cultural moments. And Kane Parsons is living proof that you don't need film school pedigree — just a good idea and the guts to execute it.
