Cineverse to Turn Trevor Henderson's Mayfair Podcast Into Found-Footage Film
Cineverse will turn Trevor Henderson's horror podcast Mayfair Watchers Society into a feature film, with Henderson producing and joining the writing team, as reported by Variety on Oct. 15, 2026.
Henderson is the Canadian artist behind two viral horror creations, Siren Head and Cartoon Cat. Siren Head is a tall, fleshless predator disguised as a siren post. Both characters started as internet images and stories before Hollywood came calling.
Mayfair Watchers Society launched in 2022 as part of Cineverse's Bloody FM podcast network. The show is told as a box of found tapes and voice recordings. Each episode follows a different resident running into a different monster in Henderson's style.
The film will keep that shape. It is planned as a found-footage anthology, meaning a collection of separate stories shot to look like discovered home videos and phone recordings. Seven creatures from the podcast are already named for the screen: The Needle, Creekman, Owls with Teeth, Mr. Bag, Anxious Dogs, Scissors and The Clatter.
Henderson will produce the film and write as part of a team. The deal was negotiated by Macias and Steven Peros, Cineverse's vice president of creative development and filmmaker relations. Henderson is represented by Verve, Redshift and Marios Rush.
The Mayfair project sits alongside two other Henderson adaptations. Rights to Siren Head went to Warner Bros. after a competitive bidding war. That film is set for the big-screen treatment from director Brian Duffield and screenwriter Zach Cregger. Separately, TriStar Pictures has acquired rights to Cartoon Cat for its own feature, according to Variety.
For listeners, this means familiar voices and monsters in a new form. The podcast was built for headphones. The film version will retell those encounters through cameras the characters themselves are supposed to be holding.
Cineverse is best known to horror fans as the genre studio behind Terrifier 3, the Toxic Avenger remake and Silent Night, Deadly Night. The company also handles theatrical re-releases. It put Guillermo del Toro's Pan's Labyrinth back in theatres on Oct. 8 for its 20th anniversary.
