Meet the Full Cast of ‘Monster: The Lizzie Borden Story’ and Who They Play (With Photos)

Netflix is preparing to release the fourth installment of Ryan Murphy and Ian Brennan’s true crime anthology, and this time the story shifts away from convicted killers toward one of the most debated cases in American history. ‘Monster: The Lizzie Borden Story’ centers on murder suspect Lizzie Borden, who was tried and acquitted of the 1892 axe murders of her father and stepmother in Fall River, Massachusetts.

The season retells one of America’s most enduring true crime mysteries, with Ella Beatty stepping into the title role as the anthology’s first female lead. Below is a breakdown of the cast bringing this Victorian era household to life, along with the real figures each actor portrays.

Ella Beatty

Ella Beatty stars as Lizzie Borden in the fourth season of Ryan Murphy’s anthology series ‘Monster.’ Murphy and Brennan chose Beatty to bring Lizzie to life after an extensive search, and she previously appeared in Murphy’s ‘Feud, Capote vs. the Swans.’

Beatty shared her excitement for the role directly with Netflix’s Tudum, saying she is looking forward to viewers experiencing the exploration of Lizzie Borden’s story and the questions her life still raises today.

Vicky Krieps

Vicky Krieps plays Bridget Sullivan, the Bordens’ live in maid. The character becomes central to the season’s narrative, as the story follows the repressed daughter of a wealthy New England family alongside her rebellious maid.

Ella Beatty was cast as Lizzie Borden in July 2025, alongside Rebecca Hall and Vicky Krieps, with Charlie Hunnam joining the cast that September.

Rebecca Hall

Rebecca Hall plays Abby Borden, Lizzie’s stepmother. Her casting places her at the center of the household dynamic that drives much of the season’s conflict.

According to creator Ian Brennan, the season explores misogyny, gender roles, and societal expectations placed on women in the Victorian era. Hall’s role as the stepmother is central to that exploration.

Charlie Hunnam

Charlie Hunnam plays Andrew Borden, Lizzie’s father. Hunnam previously portrayed Ed Gein in the anthology’s third season, marking his second turn within the ‘Monster’ franchise.

Season four of Netflix’s ‘Monster’ true crime franchise finished production, with the series set to premiere on September 17.

Billie Lourd

Billie Lourd plays Emma Borden, Lizzie’s older sister. Lourd, Joey Pollari, Sarah Paulson, and Jessica Barden round out the cast alongside the season’s leads.

Emma’s presence in the Borden household adds another family layer to the story of confinement and cruelty at the center of the season.

Jessica Barden

Jessica Barden plays Nance O’Neil, an actor friend of Lizzie’s. The friendship figures into the broader narrative Murphy and Brennan are building around Lizzie’s life after the murders.

‘Monster, The Lizzie Borden Story’ is created and written by Brennan and executive produced by Murphy, Brennan, Max Winkler, Eric Kovtun, Scott Robertson, Louise Shore, Nissa Diederich, Todd Kubrak, Carl Franklin, and Tanase Popa.

Sarah Paulson

Sarah Paulson plays 1990s serial killer Aileen Wuornos, suggesting the season will span several timelines, similar to how ‘Monster, The Ed Gein Story’ unfolded last year. Paulson is a Murphy mainstay who has appeared on several of his shows, including ‘American Horror Story,’ ‘American Crime Story,’ and ‘All’s Fair.’

Her inclusion signals that the season may connect Borden’s legacy to later true crime cases rather than staying confined to a single decade.

Joey Pollari

Joey Pollari joins the cast in an undisclosed role that has not yet been revealed ahead of the premiere. Alongside Pollari, Sarah Paulson and Jessica Barden round out the wider ensemble supporting the season’s leads.

Netflix describes the season as gory and psychological, trapping Lizzie Borden in a cruel Victorian era household before the ax murders that shock the nation. Principal photography for the season began and wrapped ahead of its premiere on September 17 on Netflix, with all eight episodes releasing at once.

With a cast this stacked and a case this debated more than a century later, which actor’s take on the Borden household are you most curious to see when the season finally axes its way onto Netflix.
