Watch: My Friend Dahmer gives glimpse into the eerie origins of a serial killer

The trailer for My Friend Dahmer was released this weekend and promises an uncomfortable, hair-raising look into the adolescence of U.S. serial killer, Jeffrey Dahmer (also known as the 'Milwaukie Cannibal').

My Friend Dahmer looks into the high school years of the serial killer, plagued with isolation, alcoholism, and the first strange stirrings of what was to come.

The chilling film is based off the 2012 graphic novel by John 'Derf' Backdef — a high school friend of Dahmer's, played by Alex Wolff. Former Disney star, Ross Lynch, plays Dahmer.
