The Witches (1990), based on Roald Dahl’s classic children’s book, follows a young boy who discovers a coven of child-hating witches led by the terrifying Grand High Witch. Mixing dark fantasy, family horror, and Dahl’s signature grotesque humor, the film has become a cult favorite for its creepy tone and Anjelica Huston’s iconic performance.
