The genre-focused studio Cineverse has officially announced a collaboration with Canadian monster creator Trevor Henderson to bring his Mayfair Watchers Society podcast to theaters. Launched in 2022 as part of the Bloody FM network, the audio series presents a series of “found tapes” that detail different residents’ encounters with Henderson’s signature creatures. The upcoming picture will translate that anthology format into a found-footage film, stitching together several of the podcast’s stand-alone stories.
Henderson will serve as producer and a member of the writing team, emphasizing his desire to stay hands-on throughout development. He praised Cineverse’s “indie-friendly philosophy,” noting that the studio’s recent output—such as Terrifier 3 and the upcoming remake of The Toxic Avenger—aligns with his vision for a low-budget, high-concept horror experience.
From podcast episodes to a cinematic anthology
The film will adopt a structure that mirrors the podcast’s episodic nature. Each segment will focus on a distinct monster, ranging from the razor-sharp legend of The Needle to the unsettling myth of Creekman. Other confirmed creatures include Owls with Teeth, Mr. Bag, Anxious Dogs, Scissors and the ominous Clatter. By presenting them as separate “found-footage” pieces, the movie aims to preserve the fragmented, rumor-like feel that made the audio series compelling.
Translating an auditory format into visual storytelling presents unique challenges. The production will need to recreate the grainy, handheld aesthetic that listeners associate with the original tapes, while also delivering clear cinematic scares. Cineverse’s experience with low-budget horror visual effects is expected to facilitate this balance, ensuring that each creature’s design remains faithful to Henderson’s internet-born artwork.
Henderson’s monsterverse gains Hollywood traction
Beyond the Mayfair project, Henderson’s creations have sparked a broader industry interest. After a competitive bidding war, Warner Bros. secured the rights to Siren Head, a towering, siren-wheeled predator, and is moving forward with a feature co-written by Zach Cregger and Brian Duffield. Shortly thereafter, TriStar Pictures acquired the rights to Cartoon Cat, another of Henderson’s viral entities, for its own adaptation.
These deals illustrate a growing Hollywood appetite for “digitally native” intellectual properties—concepts that originated on social platforms and amassed sizable fan bases before crossing over to mainstream media. Henderson’s work stands out because he retains tight control over the official canon, preventing the dilution that often accompanies fan-generated expansions. He has hinted that less-known monsters such as Long Horse, the Sisters of the Ever-Sharpening Blade, and the Upside-Down Face Man could also be primed for future screen treatment.
Cineverse’s genre pedigree and upcoming slate
Founded as a specialist in horror and cult cinema, Cineverse has built a reputation for delivering profitable low-budget titles. Recent releases include the 20th-anniversary theatrical run of Guillermo del Toro’s Pan’s Labyrinth and the upcoming sequel Terrifier 3. The studio’s partnership with Bloody Disgusting on the original podcast underlines a shared commitment to niche horror audiences.
With the Mayfair adaptation slated for development, Cineverse is positioning itself as a bridge between internet-born terror myths and traditional cinema. The company’s Vice President of Creative Development, Steven Peros, and negotiating executive Macias have confirmed that the project is moving forward on schedule, with director and additional writer selections expected later this year.
