“Monster” Season 3 is going “Psycho.”

Variety reports that Emmy winner Laurie Metcalf, Emmy nominee Tom Hollander, and British Independent Film Awards winner Olivia Williams have joined the cast of the next installment of Netflix’s massively popular true crime anthology drama series from creators Ryan Murphy and Ian Brennan. Season 3, “The Original Monster,” will follow serial killer and grave robber Ed Gein, who will be played by Charlie Hunnam. Metcalf will play Gein’s mother Augusta, a volatile religious fanatic with whom he had an extremely dysfunctional relationship.

Gein was the inspiration for the character of Norman Bates in the film “Psycho,” and that fact will be explored in “Monster,” as Hollander will be playing director Alfred Hitchcock and Williams will be playing Hitchcock’s wife Alma Reville.

“Monster” began in 2022 with “Dahmer – Monster: The Jeffrey Dahmer Story,” which is one of Netflix’s most-watched shows of all time.
