A “Jeff the Killer” movie is in the works.

Another film adaptation of a creepypasta in the wake of Backrooms, a “Jeff the Killer” movie is in development from Savanah Moss, a TikTok creator with 11.4 million followers and best known for her “fever dream” videos. Moss is partnering with creator-led studio Tongal and The Age of Adaline producers Mark Korshak and Michael McKay.

As was to be expected following the overwhelming success of Kane Parsons’ Backrooms, Hollywood is looking to creepypastas for its next big hit. The Jeff the Killer film follows news that adaptations of internet horror IP Siren Head, Cartoon Cat, and The Mandela Catalogue are all in development.

Making his first appearance on the internet in 2008, Jeff the Killer is a 13-year-old serial killer who embarks on a murderous rampage after his face is disfigured by bullies. The character is known for his heavily edited, pale face with protruding gums, no eyelids, and a permanent, carved smile.

“I grew up reading Jeff the Killer and all of the creepypasta horror stories, so there’s definitely a nostalgic connection for me,” Moss told The Wrap. “I’ve even used Jeff in some of my ‘Fever Dream’ videos in the past, so it’s crazy to fast-forward to now and actually have the opportunity to help turn this character into a feature film […] I don’t just want to recreate the creepypasta — I want to make Jeff feel terrifyingly real.”

Tongal’s decision to trust Moss with the property is surely motivated by A24’s decision to hire a then-20-year-old Kane Parsons to direct Backrooms. Inspired by an image first circulated on 4chan, Parsons’ Backrooms videos, featuring workers in hazmat suits exploring an endless maze of eerie office space, went viral and caught the attention of major studios before A24 struck a deal.

In addition to her TikToks, Moss wrote and starred in the short film Funny Bunny, which drew criticism from users across social media for its apparent use of AI-generated imagery in the film’s climactic scare.

Described as a “creator-led” studio with alternative workflows and “community workshopping”, Tongal have opened the Jeff the Killer Character Development Concept Project, which allows anyone to submit concepts outlining Jeff’s character and motivation. Five submissions will be met with a $500 reward, while an additional five will receive an “honourable mention” along with a $50 reward. The studio suggests that they would like to have one contestant “stay involved with the project”.
