British actor Charlie Hunnam stars as the titular Ed Gein, a massive shift for a performer best known as the protagonist Jax Teller in the drama series “Sons of Anarchy.” Here, Hunnam shares scenes with Laurie Metcalf as Gein’s mother, an overbearing and religious woman eerily similar to the backstory given to Mrs. Bates in “Psycho.”

Charlie Hunnam is sharing what went through his head when he agreed to play serial killer Ed Gein — and how he "fell into a full panic" after realizing the decision he made.
