But who is Slender Man? In the dark corners of the internet brewed a myth about a faceless man wearing a suit and goes by the name Slender Man. It was a man named Eric Knudsen who created Slender Man, bouyed by the massive response from internet users who asked him to edit their pictures to make them more scarier, The Guardian reports.

Slenderman is depicted as a person sporting a black suit, lurking around in the background of the picture. He has no face, is inhumanly tall and thin. The aura around him gives anyone looking at him a chill down the spine. The popularity of the myth grew to a point that people started morphing the image in their own photos and many even started creating their own version of the character.

The reel and real world horrifically met when the murder attempt took place. The documentary makers have got in touch with the girls' families to reveal the story to the world. Through this, the makers also wish to shed light on the influence of the dark corners of the internet on the impressionable young consumers.

The film also features interviews with experts who helped the girls' get through the mental trauma. It is scheduled to air on January 23. You can watch the trailer here:
