Beware the Slenderman is an upcoming documentary about the creepy internet sensation surrounding Slenderman, how it came to be, and the real-life violent acts that were inspired by it. The film premiers tomorrow on HBO.
Slenderman is a fictional character depicted as a tall, faceless man in a suit who traumatizes or abducts his victims, which primarily include children.
Three years ago, two 12-year-old girls stabbed another young girl deep in a forest in Waukesha, Wisconsin. The victim was stabbed 19 times, but managed to recover from her wounds. The two girls behind the violent act were arrested, and they told authorities that Slenderman had told them to commit the crime. This HBO documentary is meant to hone in on this strange and troubling event, as well as look deeper into the digital folklore of Slenderman.
Slenderman originated on an online forum in 2009 and quickly went viral. He has starred in video games as well, including Slender: The Eight Pages and Slender: The Arrival.
