Alex Kister to Direct the Adaptation
The film will be directed by Alex Kister, the 22-year-old creator of the original YouTube series. Kister co-wrote the screenplay with Tyler Clifton.

What is The Mandela Cat

The Mandela Catalogue is a viral analog horror series that launched on YouTube in 2021. It has accumulated over 100 million views across its episodes. The story is set in the fictional Mandela County and revolves around disturbing entities known as “Alternates,” which are shape-shifting doppelgangers that manipulate victims through psychological terror rather than traditional jump scares.

Studios are increasingly looking toward viral YouTube horror series for big-screen adaptations due to their built-in fanbases and distinctive visual styles. The Mandela Catalogue is known for its unsettling analog horror aesthetic, which mimics distorted VHS tapes and old television broadcasts. IGN
