Investigation Discovery has released a three-part documentary series тιтled Unmasking a Monster: Aileen Wuornos that employs artificial intelligence in a way rarely seen in television production. The series uses a sophisticated AI-based digital mask to transform the face of actress Morag Peacock into a close visual likeness of the late serial killer Aileen Wuornos during dramatized reenactments. The same technique was applied to nine additional actors portraying real individuals connected to the case. The program premiered on September 30, 2026, airing on Investigation Discovery and streaming on HBO Max.

Executive producer Stephen Dost, who serves as vice president of content at Arrow Media, described the technology as a highly advanced form of motion capture. He told The Hollywood Reporter that this particular application of AI represents a first for the industry. Dost explained that the production team had been aware of the digital masking capabilities for some time but waited for a story that justified its use. They wanted the technology to serve a meaningful narrative purpose rather than function as a mere technical demonstration. Wuornos’ case repeatedly stood out because her facial expressions appeared to carry the visible weight of a difficult and traumatic life.

One practical challenge was the limited amount of existing archival footage of Wuornos. Traditional true-crime reenactments have long struggled with believability, often deliberately keeping actors’ faces partially hidden or sH๏τ from abstract angles. Jason Sarlanis, president of Investigation Discovery, noted that audiences increasingly seek greater realism and a stronger sense of connection to the events being depicted. By combining strong performances with digital enhancement, the series aimed to allow viewers to look more directly at the human presence in these moments.

Selecting the right actress was essential. At the stage of technological development available during production, the team needed a performer whose facial structure was broadly similar to Wuornos’. Peacock fit that requirement. She prepared with roughly 90 minutes of hair, makeup, and a prosthetic tooth before filming. Once cameras rolled, she concentrated on capturing Wuornos’ specific mannerisms, eye movements, and emotional expressions, treating the ᴀssignment as a conventional acting role. Peacock later said she was pleasantly surprised by the finished result and could still recognize herself beneath the digital layer. Members of her family recognized her as well.

Peacock initially approached the project with caution when she learned AI would be involved—a reaction she described as common. After discussions with her agent and a clear explanation that the technology functioned essentially as advanced CGI layered over her own performance rather than creating an independent digital clone, she became comfortable with the process. Dost stressed that the technology was not a production shortcut. Using it carefully and ethically actually slowed the workflow considerably and required approximately three years of development and refinement.

The production established a clear ethical framework. Consent was obtained from living participants who appeared in interviews or were portrayed on screen, as well as from the actors involved. The technology was not applied in cases where consent could not be secured, including one investigator who died after giving an interview and Wuornos’ former partner, who declined to participate. Every reenacted scene was drawn strictly from legal transcripts, police records, and the recollections of interview subjects; nothing was invented for dramatic effect. The team also committed to transparency with viewers about the methods used.

The series arrives near the same period as Ryan Murphy’s Monster anthology on Netflix, which features Sarah Paulson in a supporting role as Wuornos. Dost described the timing as coincidental and potentially helpful for generating public interest, while noting that the two projects differ significantly in approach. One remains closely tied to documented testimony and records, while the other incorporates fictionalized elements.

Unmasking a Monster: Aileen Wuornos represents an attempt to expand the visual language of true-crime storytelling by combining careful performance work with emerging digital tools, while adhering to a set of ethical guidelines intended to maintain authenticity and respect for the real people involved.
