A terrifying new trailer for HBO’s Slenderman documentary has been revealed, and it’s not for the faint hearted.
Beware The Slenderman focuses on the case of two Wisconsin teenagers, who attempted to murder their friend after being inspired by the viral character.
12-year-old girls Morgan Geyser and Anissa Weier, who have since been diagnosed with mental illness, stabbed their friend Payton Leutner to become “proxies” of the urban myth inspired by the fictional boogeyman.
Morgan and Anissa lured Payton into the woods and attempted to kill her to try and prove the character’s existence in 2014. They are currently facing trial.
The sinister figure first appeared on the Something Awful forum in 2009 after being created by Eric Knudsen.
Beware The Slenderman will air on HBO on January 23, 2017. Watch the trailer below:
