Thomasin Harcourt McKenzie (born 26 July 2000) is an actress from New Zealand. After a minor role in The Hobbit: The Battle of Five Armies, she rose to critical prominece with the lead role in Debra Granik's 2018 drama film Leave No Trace. After supporting roles in the 2019 films The King, Jojo Rabbit and True History of the Kelly Gang, as well as the 2021 thriller Old, Edgar Wright's psychological horror film Last Night in Soho established her as one of the industry's lead actresses.

Set in the quiet Midwestern town of Ravenwood, Illinois, DAD ATE MOM! follows Ethan Harper, a weary but devoted factory worker and father of three, whose seemingly normal suburban life begins to unravel after his young children start saying things no child should know. Their calm, unsettling statements—about death, mirrors, and things hiding beneath beds—are dismissed as imagination at first, until Ethan’s wife Mary mysteriously vanishes without a trace. As neighbors begin to disappear and the police fail to act, Ethan uncovers disturbing clues hidden inside his own home: childlike drawings, ritualistic patterns, and signs suggesting that something is spreading from family to family. What begins as a psychological mystery escalates into a brutal suburban slasher, where children watch silently from the background and violence feels disturbingly domestic. The film builds toward a chilling revelation—this is not one broken household, but a chain—and ends with a haunting question: what if children aren’t imagining anything at all?
