Steven Spielberg and Amazon are turning a viral YouTube nightmare into a big-screen horror event

Bit of a surreal one in film news today: Steven Spielberg is throwing his weight behind the film adaptation of a YouTube horror series. Yep, we’re genuinely living in a timeline where YouTube creepypasta lore is now proper fodder for the Hollywood machine. And after the bonkers numbers for Backrooms, it doesn’t look like this trend is going anywhere.

Spielberg, Amazon & One Seriously Creepy Web Series

If you’re not glued to horror corners of YouTube, maybe you’ve missed this one: The Mandela Catalogue. Spielberg and Amazon MGM Studios are developing it for the big screen, based on reports from the trade press. It’s not some random acquisition either—Alex Kister, the creator of the original series, is apparently lined up to direct the live-action film version. He’s written the script himself, with the help of Tyler Clifton.

Wait, What Exactly Is The Mandela Catalogue?

The series is considered a flagship for the so-called analog horror genre on YouTube (think retro VHS glitches, PSAs gone wrong, and a general air of late-90s digital decay). Kister launched it in 2021 and, to date, it’s pulled in over 100 million views across two seasons. That’s not an exaggeration—100 million, on a YouTube series about a creepy version of Wisconsin. It sits alongside web-horror staples like Local 58 and The Backrooms as one of the trend-defining titles.

The basic setup: Mandela County, Wisconsin gets besieged by these uncanny, shape-shifting entities called Alternates. These things aren’t just your average monsters— they’re led by a twisted take on the Archangel Gabriel, and their whole mission is to psychologically torment people until they kill themselves. Yes, it’s as grim as it sounds. The Alternates are ace at hijacking electronics too—televisions, computers, GPS, the works. The tension comes from the series’ agonisingly slow-burn approach and those analog horror trappings: distorted public warnings, haunted tapes, and all that glitchy dread.

Analog Horror Gets Studio Backing

Let’s be honest, a few years ago the idea of Steven Spielberg producing a feature version of a YouTube horror experiment would have sounded like a fever dream. But this is the world we’re in—Kane Parsons’ Backrooms adaptation and Curry Barker’s Obsession both made serious box office dents in 2026. Now, Kister is the next web creator to get the big studio treatment, with Spielberg himself (and Spielberg’s regular producing partners Aaron B. Koontz and Nick Nesbitt) bankrolling the project. Kister and Tyler Clifton are producing as well, presumably because no one’s letting go of their IP in this scenario.

• Director: Alex Kister (creator of the original series)
• Co-writer: Tyler Clifton
• Producers: Steven Spielberg, Aaron B. Koontz, Nick Nesbitt, Alex Kister, Tyler Clifton
• Status: Script stage, no release date yet
• Studio: Amazon MGM Studios
• Franchise: Based on the YouTube series, with over 100 million views
• Plot basics: Shape-shifting "Alternates" infiltrate Mandela County, psychologically torment residents, and manipulate electronics

The whole thing is one of those 'blurring-the-lines-between-internet-fan-fiction-and-Hollywood-proper' jobs. Spielberg producing a YouTube-born horror could have a fair few horror nuts and analog tape obsessives feeling rather smug right about now.

There’s no official word on a release window or casting yet, but with Spielberg and Amazon in the mix, it seems safe to assume this won’t be another low-rent streaming quickie. As soon as details on the production start leaking, you’ll probably see it everywhere.
