Beware The Slender Man is a HBO documentary film base on a real life events of two 12 year-old girls, Morgan Geyser and Anissa Weier who were accused of stabbing their friend 19 times in 2014. Shortly after the incident the two accuses were found wondering in the woods miles away from the body searching for The Slender Man’s mansion. The urban legend of The Slenderman is a fictional monster from internet Creepypasta where horrible images and stories of ghost and aliens are fed to readers like a campfire story telling sit in. The opening scene of the HBO documentary quote of “The palest man, the blackest suit, quicker than the tallest brute…The Slender Man, for he can do what no one can.” is taken from one of the many poems written about the fictional monster. The myth of the tall and gangly monster with a faceless white head was originated by Eric Knudsen on the website that often inter mixes images with real and fictional stories that involve mysterious disappearance of children or brutal acts of violence done against them. Hence the birth of an urban legend. Beware The Slenderman will debut on HBO January 23rd 2017. Check out the trailer below.
