The woman performing as Aileen Wuornos in the new ID and HBO Max docuseries is the actress Morag Peacock. The face viewers will see is not hers. It is a three-dimensional model of Wuornos, built from archival video and photographs and laid over Peacock’s performance with the help of AI: a digital mask of one of the most retold killers in American true crime, worn by a performer hired to play her.

Unmasking a Monster: Aileen Wuornos is a three-part true-crime docuseries made for Investigation Discovery by Arrow Media, a Fremantle company, and streaming on HBO Max. It goes back over the killings of seven men in Central Florida, the investigation that ended with her arrest and her years on death row, using first-person accounts from Wuornos, from people close to her and from the investigators who worked the case. Warner Bros. Discovery owns both the channel and the streamer, so one company is putting a synthetic face on a real killer in front of its cable audience and its streaming audience at the same time.

The facts are not the new part. Wuornos has been filmed, dramatized and re-examined for more than three decades, and Arrow Media itself already made Aileen Wuornos: Mind of a Monster for the same network. What ID is selling this time is a method. The network says the technology was used “exclusively for the series’ visual presentation,” that the writing and narrative were based “entirely” on verified transcripts, documented evidence and firsthand accounts, and that the recreations are “not meant to create instances that did not take place.” Put plainly, the words are sourced and the face is manufactured.

The mechanics are unusually well documented for a true-crime launch. Kyran Speirs, head of post-production at Arrow Media, told Deadline that the team built a model from real archival video and real photos that captured Wuornos “from every angle,” a model that “acts as a three-dimensional mask” layered on top of the actress’s performance with the help of AI. ID says the production took three years and more than 100 crew members. Other people in the story are also played by actors whose likenesses were digitally replicated, and the Wuornos layer includes a replicated voice. Peacock described the process as “putting on a costume,” then went further: “It’s almost as if she’s been brought back to life.”

That last sentence is the one ID has to manage. The network says every person whose likeness was replicated was informed and consented, and that the families of the victims were briefed about the production. Wuornos cannot consent; the state of Florida executed her. Her likeness is rebuilt from footage that other people shot of her over the years, and the series applies it to words she put on the record. Whether a verified transcript is enough to license a performed face is the question the premise raises, and it is not one a press release can settle.

The case itself is documented. Wuornos, who was working as a sex worker, killed seven men across Central Florida in 1989 and 1990 and claimed they had raped or tried to rape her. She was arrested in January 1991 in Volusia County, convicted in 1992 of the murder of Richard Mallory, pleaded no contest to five other killings and received six death sentences. Florida executed her by lethal injection in October 2002.

Culture got there long before the VFX artists. Nick Broomfield made two documentaries about her, Aileen Wuornos: The Selling of a Serial Killer and Aileen: Life and Death of a Serial Killer, the second co-directed with Joan Churchill. Patty Jenkins’ Monster turned Charlize Theron into Wuornos and won Theron the Oscar for best actress. All of those works fought over the same question: whether the woman at the center was a predator, a product of the men and institutions around her, or both. The new series walks into that argument with a tool none of them had, and its title, which promises to unmask, sits oddly next to a method built on wearing a mask.

The industry context explains the timing. Since the 2023 actors’ strike, digital replicas have been a contract term in Hollywood, negotiated clause by clause for living performers. Non-fiction has far fewer rules, and true crime, which fills ID’s schedule and is a staple of HBO Max’s documentary catalog, has every commercial reason to want recreations that look like the real people. Jason Sarlanis, president of ID, framed the project as evolution: documentary storytelling “has always evolved alongside advances in filmmaking,” he said, adding that “every scene was meticulously informed by legal transcripts and firsthand testimony.”

Read that way, Unmasking a Monster is less a new account of Wuornos than a test run of a rulebook: transcripts as the script, consent from the living, briefings for the victims’ families and a synthetic face for the dead. If audiences accept it on a case this familiar, the method will not stay with her. It will become the house look of the next wave of true crime, and the paperwork will be the only thing separating a reconstruction from an invention.

What the series cannot settle, by design, is who is speaking. The words belong to the record. The performance belongs to Morag Peacock. The face, and the voice layered over hers, belong to a model built from old footage. When the Wuornos on screen repeats something the real Wuornos said, viewers will be watching three sources at once and calling them one woman.

Unmasking a Monster: Aileen Wuornos premieres Wednesday, September 30, from 8 to 11 p.m. ET/PT on ID, with all three parts airing back-to-back, and is available to stream on HBO Max, where it is rated TV-MA.

Is Unmasking a Monster: Aileen Wuornos a true story? Yes. It is a documentary about the real Wuornos case. The recreated scenes are dramatizations that ID says are drawn from transcripts, documented evidence and firsthand accounts.

Who plays Aileen Wuornos? Morag Peacock performs the role, with a digital likeness of Wuornos layered over her performance.
