Charlie Hunnam traded his clean-shaven look as Ed Gein for a scruffy beard and a head of shaggy hair as he transformed into Andrew Borden for the fourth season of Netflix’s hit crime drama, Monster: The Lizzie Borden Story. The Sons of Anarchy actor, 45, was spotted on set in Los Angeles, Calif., wearing an ankle-length brown robe with deep red embroidery over what appeared to be a long, white night gown and a pair of black slippers in photos shared on social media by fans. Embracing the fatherly look, his beard had patches of gray in it. He also had a single, gold ring on the small finger of his right hand.
In other photos, Ella Beatty (If I Had Legs I’d Kick You), who plays the role of Lizzie, could be seen in a baby pink dress wearing a wreath of flowers on her head and a pair of light brown ankle boots. At one point, she walked alongside Vicky Krieps (The Phantom Thread), who is set to star as Borden family maid Bridget Sullivan. She was in a simple dress and apron. A final image revealed Rebecca Hall (Godzilla Vs. Kong) — who plays Abby Borden — peering past a curtain out of a window while sporting a deep purple dress with buttons trailing down the front, according to What’s On Netflix.
Additional stars joining the cast for Season 4 include Billie Lourd (Scream Queens) as Lizzie’s sister Emma Borden, and Jessica Barden (American Horror Stories) as Lizzie’s friend Nance O’Neill.
Monster’s First Female ‘Killer’ Was Acquitted
Past seasons of Monster have delved into the complicated inner workings of notable killers such as Jeffrey Dahmer and Ed Gein, but the upcoming installment will focus on a woman who was never actually found guilty of a murder. Season 4 explores the life of Lizzie Borden — young woman who was accused of brutally killing her father and stepmother with an axe in 1892 in Fall River, Massachusetts. The killings were particularly violent, with Abby reportedly being hit more than 17 times in the attack, while Andrew was said to have been struck around 10 times with the hatchet.
Lizzie was charged with their murders, and in 1893, she went to trial. However, she was eventually acquitted due to lack of evidence — including disputes about whether she was even in the home at the time of the crimes and if they had properly identified the supposed murder weapon. While there have been many theories over the years on why she could have done it or who else could have been responsible for their deaths, she’s still gone down in history as an alleged killer, with many movies, television shows and even children’s rhymes associating her with the infamous crimes.
Filming for Monster: The Lizzie Borden Story is expected to continue into early 2026. There is currently no announced premiere date for the new season. Until then, true crime fans can catch the most recent installment, Monster: The Ed Gein Story, streaming on Netflix.
