Netflix's Monster anthology continues to expand its cast for Season 4, with Billie Lourd and Jessica Barden officially joining the lineup. The crime thriller series, created by Ryan Murphy and Ian Brennan, will begin production later this year. While Season 3 Monster: The Ed Gein Story, starring Charlie Hunnam is set to premiere on October 3, anticipation is already building for the next installment. Notably, Jessica Barden’s husband, Max Winkler, will serve as a director for the new season. Monster previously dramatized the chilling cases of Jeffrey Dahmer and the Menendez brothers.
