Following the breakout success of Backrooms, Hollywood has begun investing heavily in horror franchises that originated online.
From analog horror series to creepypastas and internet urban legends, several viral properties are now being adapted into feature films. This list will continue to be updated as more projects are announced.
More Backrooms
While nothing is official, Kane Parsons has said he’s interested in exploring a sequel or TV series around the $350M+ box office phenomenon that helped kick off Hollywood’s interest in internet horror.
The Mandela Catalogue
One of the most acclaimed analog horror series ever created, The Mandela Catalogue is being adapted by Amazon MGM Studios and Spielberg’s Amblin Entertainment after an 11-studio bidding war. Creator Alex Kister is set to direct the film himself, making it one of the rare internet horror adaptations led by its original creator.
Siren Head
Trevor Henderson’s towering cryptid is officially headed to theaters. Warner Bros. is developing Siren Head with Weapons and Barbarian filmmaker Zach Cregger co-writing the screenplay alongside Brian Duffield, who is also attached to direct.
Cartoon Cat
Another of Trevor Henderson’s creations, Cartoon Cat, is also in development as a feature film at Sony’s TriStar Pictures.
Cartoon Cat is an ancient, malevolent entity disguised as a vintage rubber-hose cartoon mascot. Unlike a traditional monster, the creature is often described as an interdimensional being that manifests through belief and can seemingly cross into our reality from its own. Henderson has portrayed Cartoon Cat as one of the most powerful and dangerous entities in his mythology, capable of taking exaggerated cartoon forms while using its playful appearance to mask a far more sinister nature.
V/H/S: SCP
The SCP Foundation is making the jump to film through V/H/S: SCP, a crossover between the long-running V/H/S anthology series and the collaborative SCP universe. The project will bring the internet’s expansive collection of paranormal entities and containment files to the found-footage format, with a planned 2027 release.
More Projects Are Likely Coming
With studios increasingly turning to YouTube, Reddit, and internet mythology for new franchises, this trend appears to be just getting started. As additional internet horror adaptations are announced, this article will continue to be updated with the latest projects currently in development.
