Here’s something that will pair nicely with your feeling of impending doom: HBO has released the trailer for its documentary Beware the Slenderman, which is set to bow in January 2017. The doc will chronicle the case of Morgan Geyser and Anissa Weier, who at 12 years old were accused of stabbing their classmate Payton Leutner 19 times to appease a legendary figure (by way of meme) known as the Slender Man. The non-fatal stabbing occurred May 31, 2014, and their case has been pending since (you can read a summary of its developments here).
Beware the Slenderman, directed by Irene Taylor Brodsky, played SXSW earlier this year to acclaim—it currently has an 83 percent on Rotten Tomatoes.
