As if people need anything else to be fearful of, HBO dropped its creepy-ass trailer for Beware the Slenderman Thursday, a documentary that focuses on the true crime story of the fake online boogyman and the trial of young girls who tried to kill for him.
Back in 2014, two 12-year-old girls in Wisconsin attempted to murder a fellow classmate by coaxing the third girl into the woods and brutally stabbing her 19 times. The victim somehow survived, and the girls were arrested.
When interrogated by police, the tweens said that the murder was a sacrifice to Slenderman—a tall, faceless, and fully fictional character who was originally created during a creepy Photoshop contest on the site Something Awful.
The movie premiered at South by Southwest earlier this year and will air on HBO January 23, and it looks both sad and terrifying. Give the trailer a watch above.
