The film, based on John Backderf's 2012 graphic novel, follows Backderf's real life experience and explores what it was like being friends with Dahmer in their teenage years.
The trailer is quick to establish glaring differences between Dahmer and his classmates, and is filled with eerie foreshadowing into his future.
The visuals are truly haunting, filled with images just innocent enough to appear normal on the surface, but just off enough to be chilling.
My Friend Dahmer comes to theaters Nov. 3rd, 2017.
