Based on the bestselling graphic novel by John “Derf” Backderf, My Friend Dahmer explores the rapidly disintegrating mind of a high schooler (Ross Lynch) who’d go on to murder (and occasionally eat) 17 men and boys between 1978 and 1991. The film isn’t mere conjecture, either — Backderf was a friend of the real Jeffrey Dahmer while growing up.
“It [will be] a lot like the book,” Backderf tells Rolling Stone, “where you go into it expecting a certain thing and you get to the end and it’s something completely different. It’s not a slasher film – it’s a very melancholy tale full of regret and remorse that shows this young kid spiraling into madness.”
