M3GAN’s cast must contend with a killer doll, and their characters have to watch their backs at every turn. Directed by Gerard Johnstone from a screenplay by Akela Cooper, M3GAN is one of the first major movie releases of 2023, and it delivers what is expected for audiences’ entertainment.
M3GAN establishes its leading lady as someone to watch in the horror genre. The film, which has comedic moments despite it being a horror, brings together a strong cast to tell its story. Led by Allison Williams, who previously starred in one of Jordan Peele’s hit horror movies, M3GAN assembles a cast of characters who must go toe-to-toe with an AI doll that begins to take on a life of her own. The cast is small, but memorable, with each actor giving a performance that aids the overall narrative.
Allison Williams as Gemma
Gemma is a roboticist who works at the toy company Funki. While she’s tasked with making the company’s latest toy cheaper, Gemma believes M3GAN, an AI doll she created, will be a game-changer. Gemma is portrayed by Allison Williams, who is best known for her roles in Peele’s acclaimed horror film Get Out, the HBO series Girls, the Netflix show A Series of Unfortunate Events, and The Perfection.
Violet McGraw as Cady
Cady James is Gemma’s orphaned niece, whose parents died in a car accident. Cady is paired with M3GAN, and comes to rely on her for everything. Cady is portrayed by Violet McGraw, who is best known for her roles in Netflix’s horror series The Haunting of Hill House, the Marvel Cinematic Universe film Black Widow, in which she played a younger version of Florence Pugh’s Yelena, and Doctor Sleep.
Amie Donald & Jenna Davis as M3GAN
M3GAN, which stands for model 3 generative android, is an AI doll that has emergent capabilities. By being paired with Cady, M3GAN is able to learn, listen, and grow, far exceeding her parameters to the point of becoming deadly. Amie Donald provides the physical movement for M3GAN in the horror comedy, while Jenna Davis voices the AI doll. Donald has previously been in the TV series Sweet Tooth, while Davis is best known for the animated series Treehouse Detectives, Vampirina, and the Disney Channel series Raven’s Home.
