Netflix Monster Season 4: The Lizzie Borden Story Release Date and Cast
Netflix will premiere Monster: The Lizzie Borden Story on September 17, 2026, marking the fourth installment of Ryan Murphy and Ian Brennan’s true-crime anthology. The eight-episode season stars Ella Beatty as Lizzie Borden and features Charlie Hunnam as Andrew Borden, according to ComingSoon.
The Casting Strategy and Narrative Pivot
Ella Beatty leads the ensemble as Lizzie Borden, a role she describes as a study in “female rage and repression,” according to ComingSoon. The supporting cast includes Rebecca Hall as Abby Borden, Billie Lourd as Emma, and Jessica Barden as Nance O’Neil.
Charlie Hunnam returns to the anthology. He previously starred as Ed Gein in Monster: The Ed Gein Story, and now portrays Andrew Borden, the victim of the 1892 axe murders.
The official logline frames the story as a descent from a “house built on humiliation and cruelty” into a “fantasy of sex, power, and revenge,” according to ComingSoon and Yahoo.
Historical Context and the “Monster” Blueprint
The 1892 case of Lizzie Borden remains one of the most debated trials in American history. Accused of killing her father and stepmother with an axe, Borden was acquitted, leaving the murders officially unsolved.

From a production standpoint, an eight-episode order written by co-creator Ian Brennan suggests a tight, focused arc.
Comparing the “Monster” Evolutions
The shift toward Lizzie Borden marks the first time the series has centered on a female protagonist. While previous seasons focused on the “monstrous” nature of the killers, Beatty notes that this season delves into the repression that fuels the violence.
