CHARLIE Hunnam looked unrecognisable as he transformed into serial killer Ed Gein for a new series.

Brit Hollywood heartthrob Charlie, 44, is set to star as the notorious murderer and body snatcher in the third season of Netflix’s anthology series Monster.

The project has faced much criticism for its previous installments but remains highly anticipated.

Upon its debut in 2022, a family member of one of Jeffrey Dahmer’s victims told how they were left ‘retraumatised’ by Evan Peters’ portrayal.

And the Menendez brothers’ formidable former defense attorney, Leslie Abramson, slammed the second season as being a “piece of s**t”.

On location in Los Angeles, Charlie adopted a clean-shaven look and a gelled-down comb-over hairstyle.

The actor was seen wearing a brown and green, striped button-down shirt layered with a red, plaid worker’s jacket.

He paired his get-up with brown straight-leg trousers and distressed leather lace-up boots.

On set, Charlie was photographed chatting with a police officer in his 1950s-inspired outfit.

Unlike the chilling role he is playing, Charlie appeared cheerful and relaxed as he interacted with cast and crew in between scenes.

Vicky Krieps, Charlie’s co-star, was also seen on set, wearing a bright yellow dress, a blonde wig, and taupe trainers.

The Monster anthology series first gained attention with Evan’s chilling portrayal of Jeffrey two years ago.

Murderer Dahmer, also known as the ‘Milwaukee Cannibal’, raped and killed 17 men and boys.

The crimes occurred between 1978 and 1991 and involved the dismemberment of his victim’s bodies.

Jeffrey was found to be legally sane at the time of his trial, despite being diagnosed with borderline personality disorder and psychotic disorder.

While serving sixteen life terms in prison for murder, Dahmer was beaten to death by fellow inmate Christopher Scarver.

And, this year, Monsters told the story of Lyle and Erik Menendez, who were sentenced to life without parole after killing their parents in 1989.

The brothers alleged they were sexually abused by their father, Jose, and their mother, Kitty, turned a blind eye before they killed them with shotguns at their Beverly Hills home in 1989.

The upcoming third season will also feature Tom Hollander, Laurie Metcalf, and Olivia Williams in prominent roles.

Carl Franklin, who worked on the first two installments of Monster, is returning to direct.

Ryan Murphy and Ian Brennan will continue as executive producers for the series.

Filming began last month and is scheduled to continue until March 31, 2025.

No official release date has been confirmed.

Gein, the character Charlie is portraying, was a notorious American murderer and body snatcher.

Known as the “Butcher of Plainfield,” Gein exhumed corpses and used the remains to create disturbing items, including furniture and clothing.

Gein’s crimes led to his arrest in 1957, and he spent nearly 30 years in a psychiatric hospital before dying of lung cancer aged 77 on July 26, 1984.

Ryan announced Charlie’s casting in September while promoting Monsters: The Lyle and Erik Menendez Story.
