Netflix has unveiled the trailer for Monster: The Ed Gein Story, the newest chapter in Ryan Murphy and Ian Brennan’s true-crime anthology. Charlie Hunnam takes on the role of the notorious Wisconsin killer who inspired Psycho and The Texas Chain Saw Massacre. For the part, Hunnam shed nearly 30 pounds to portray Gein’s frail, eerie presence, and the trailer shows him in a chilling mask made from victims’ skin. The series, also starring Laurie Metcalf, Suzanna Son, Tom Hollander, and Addison Rae, premieres Oct. 3 on Netflix.
