The ‘DAHMER - Monster: The Jeffrey Dahmer Story’ Cast Revealed (2024)

Emmy Award–winning director Ryan Murphy’s new 10-episode limited series,DAHMER — Monster: The Jeffrey Dahmer Story, will give notorious serial killer Jeffrey Dahmer’s victims a voice. There have been countless films and documentaries about Dahmer, includingNetflix’s upcomingConversations with a Killer: The Jeffrey Dahmer Tapes. Yet forDAHMER, Murphy and his team – consisting of co-writer Janet Mock, who also co-directed the series with Carl Franklin – will showcase the points of view of the Milwaukee Monster’s victims. The series, which is a fictionalized account of actual events,will also take a critical look at systemic racism, white privilege, hom*ophobia and the institutional failures that allowed Dahmer to murder and dismember 17 boys and men from 1978 to 1991. These men and boys were mainly underage and people of color. At least five of Dahmer’s victims were killed after law enforcement was alerted to the killer’s behaviors. Here’s the cast ofDAHMER.

Evan Peters

Jeffrey Dahmer

Though he appears to be an average clean-cut guy on the surface, there is something very sinister about Jeffrey. He often seems standoffish, and his violent outbursts send everyone on high alert, including his parents, who’ve long tried to ignore his unsettling and sometimes outright evil behavior.

Peters is no stranger to Ryan Murphy projects. AnAmerican Horror Story veteran, he’s also had roles in everything from theX-Menfranchise andWandaVisiontoPoseandMare of Easttown. When he was cast inDAHMER, Peters did extensive research. “It felt important to be respectful to the victims, to the victims’ families,” the actor toldNetflixQueue. “To try and tell the story as authentically as we could. And you need to have certain plot points because he did do these things, but you don’t need to embellish them; we get it. You don’t need to see them over and over again.”

Lionel Dahmer

DAHMER spans several decades, so viewers will get some insight into Jeffery’s childhood. His father, Lionel, fails to form a real connection with him. Instead, he focuses on his work and inflicts emotional abuse on his first wife, Joyce (Penelope Ann Miller). When Jeffrey becomes obsessed with dead animals and bones, he begins to realize something is horribly wrong with his eldest son. By then, though, it’s far too late.

Jenkins has worked in Hollywood for nearly five decades. He’s best known for his roles on HBO’sSix Feet Under,Step BrothersandThe Shape of Water. For his work in Guillermo del Toro’s fantasy-drama, Jenkins was nominated for an Academy Award, Golden Globe and Screen Actors Guild Award.

Niecy Nash

Glenda Cleveland

A single mother living next door to Jeffrey in a Milwaukee apartment building, Glenda becomes increasingly disturbed by her neighbor’s erratic behavior. After seeing suspicious activity, smelling foul odors and hearing screams and power tools from Jeffrey’s apartment, she becomes certain that he is up to something. She begins consistently reporting him to the apartment building management and the police. However, because Gloria is a Black woman, her concerns are largely ignored, with Jeffrey getting no more than a slap on the wrist. When Gloria’s concerns are finally taken seriously, it’s far too late. “When you hear the different things that happened with regards to Jeffrey Dahmer and his victims, Glenda was one of his victims too,” Nash toldNetflixQueue. “And her story has been told the least of these.”

Nash has collaborated with Murphy before on series likePopularand Scream Queens. The Emmy Award-winning actor is known for her stellar roles inGetting On,ClawsandWhen They See Us. She has also been in countless films, including Ava DuVernay’s Selmaand Netflix’sUncorked.

Concerned about his home life and erratic behavior, Jeffrey’s grandmother Catherine opens her home to him. Deeply religious, she believes that a change in environment will help set him on the right path. It does, initially. But as his behavior becomes increasingly creepy and odd, Catherine can no longer excuse her grandson’s behavior. Three of Jeffrey’s earliest victims were killed or dismembered in Catherine’s home

Penelope Ann Miller

Joyce Dahmer

Unable to give Jeffrey attention due to her battles with mental illness and an emotionally abusive relationship with her husband, Penelope has very little to offer her son emotionally. Things get worse after she begins numbing herself with alcohol, sleeping pills and other drugs.
