Cineverse has struck a deal with the creator of Siren Head and Cartoon Cat to bring the popular horror anthology to the big screen, expanding a franchise that has amassed more than 3 million downloads since its debut in October 2022.

First reported by Variety, the deal will see Henderson work closely with Cineverse on the feature film while the original podcast continues. The show’s fourth season is also on the way.

The announcement arrives as Hollywood increasingly turns to internet-born horror for new genre projects. Henderson, whose unsettling creature designs have developed a massive online following, is already seeing other creations make the jump to film.

The upcoming Mayfair Watchers Society movie will take the form of a found-footage anthology, featuring different creatures and stories drawn from the podcast. Among the monsters expected to appear are The Needle, Creekman, Owls with Teeth, Mr. Bag, Anxious Dogs, Scissors, and The Clatter.

Created by Henderson and Pacific Obadiah, Mayfair Watchers Society presents its stories through fictional found recordings and audio accounts. Each episode follows different residents as they encounter strange and terrifying creatures inspired by Henderson’s distinctive monster designs.

Since launching in October 2022, the podcast has attracted millions of downloads, establishing Mayfair Watchers Society as one of Henderson’s notable horror properties. Its anthology format also offers the filmmakers an opportunity to bring multiple creatures and stories together in a single feature.
