M3GAN (pronounced “Megan”) is a 2022 American science fiction horror film directed by Gerard Johnstone. It was written by Akela Cooper from a story by Cooper and James Wan (who also produced with Jason Blum). Allison Williams and Violet McGraw star, Amie Donald physically portrays M3GAN, and Jenna Davis voices the character. Its plot follows an artificially intelligent doll, who develops self-awareness and becomes hostile toward anyone who comes between her and her human companion.

M3GAN premiered in Los Angeles on December 7, 2022, and Universal Pictures theatrically released it in the United States on January 6, 2023. The film grossed over $181 million worldwide against a budget of $12 million and received praise from critics for its campy blend of horror and humor. A sequel, titled M3GAN 2.0, is scheduled to be released on June 27, 2025. After her parents are killed in a car accident, eight-year-old Cady is sent to live with her aunt Gemma, a roboticist at the high-tech Seattle toy company, Funki. Gemma is covertly using the company’s resources to develop M3GAN (Model 3 Generative Android), a child-sized humanoid robot doll powered by artificial intelligence, designed to be the ultimate companion for children. During an unsuccessful test of M3GAN in their lab, Gemma’s boss, David, discovers the project and orders her to discontinue work on it. Gemma and Cady struggle to connect until Cady comes across Bruce, a motion capture robot that Gemma had created at college. Watching Cady with Bruce, Gemma is motivated to complete M3GAN.

When the prototype M3GAN is formally paired with Cady, David is convinced of the project’s potential for success. M3GAN exceeds expectations and begins to take on a parental role. Gemma’s colleagues, Tess and Cole, as well as Cady’s therapist, Lydia, become concerned about Cady developing an unhealthy emotional attachment to M3GAN. M3GAN starts operating more independently and targets anything that she deems a threat to Cady: she kills Dewey, the dog of Gemma’s neighbor Celia, after it attacks both her and Cady while in the front yard. Later, M3GAN attacks Brandon, a boy bullying Cady, and pulls off his ear; when she chases him, he falls into the road and is run over by a passing car.

After Celia blames Gemma for Dewey’s disappearance, M3GAN fatally sprays her with insecticide after shooting her with a nail gun. Gemma becomes suspicious of M3GAN and attempts to check her video logs, only to find the files corrupted or deleted. Gemma powers M3GAN off and brings her to the lab, where she, Tess, and Cole attempt to fix her. Cady becomes distraught when separated from M3GAN and slaps Gemma. Gemma apologizes for her inattentiveness and tells Cady that M3GAN is only a distraction that helps her cope with her loss, not a solution.
