Slender Man is a horror monster created by the goons on the SomethingAwful.com forums many moons ago. Mr. Slender then went on to become a series of YouTube videos in the guise of a documentary on a lost film entitles “Marble Hornets” telling the tale of a man who went crazy filming.
He kept seeing this Slender Man and slowly lost his mind. It was an incredibly well done series that had people going nuts because this was a time before these sorts of things were done on YouTube. Sure, nowadays this would be some viral marketing campaign, but back in the early days YouTube was actually a place for fresh ideas and projects.
Comic Book.com has exclusively revealed Screen Gems has a fall 2016 production date slated for filming to begin on a Slender Man film. Already deep in development, a script has been written by David Birke a veteran of indie horror projects.
