After the Backrooms buzz, another horror phenomenon from YouTube will be entitled to its cinema adaptation, with Steven Spielberg producing.

The wave of adaptations of creations born on YouTube is only growing.

After the worldwide success of Backroomsand while waiting for Siren Head by Zach Cregger, it’s Steven Spielberg’s turn to bring YouTube to the big screen.

Launched in 2021, The Mandela Catalog now has two seasons and more than 100 million views on YouTube. It is considered one of the references of “analog horror”, alongside Room 58 And Backrooms.

The story takes place in the fictional Mandela County, Wisconsin, where particularly disturbing shapeshifting creatures called the Alternativesinvade the region.

They are also capable of manipulating computers, televisions and even GPS.

On The Mandela CatalogSteven Spielberg, fresh from the triumph of Disclosure Daywill serve as producer alongside Aaron B. Koontz, Nick Nesbitt, Alex Kister and Tyler Clifton.
