HBO have released the first trailer for their forthcoming documentary Beware the Slenderman, and let’s just say it looks pretty darn terrifying. Telling the chilling true crime story, the film details two 12 years old girls, who in 2014 attempted to murder their classmate after luring her out into the woods in an attempt to appease the ‘Slenderman’ – a fictional character created in 2009 by forum user Erik Knudsen.
The supernatural figure is depicted as an unnaturally tall and thin, suited man with a blank, featureless face. He has inspired many works of fan fiction and meme imagery online. Stories regularly feature the character abducting and harming children.
Beware the Slenderman will air on HBO in January 23, 2017. It premieres at Doc NYC festival this Saturday (November 12). Check out the haunting trailer and poster below.
