The Whip and the Body (Italian: La frusta e il corpo) is a 1963 gothic horror film directed by Mario Bava under the alias "John M. Old". The film is about Kurt Menliff (Christopher Lee) who is ostracized by his father for his relationship with a servant girl and her eventual suicide. He later returns to reclaim his title and his former fiancée Nevenka (Daliah Lavi) who is now his brother's wife. Menliff is later found murdered, but the locals believe his ghost has returned to haunt the castle for revenge.

Italian censors removed the film from cinemas due to its sadomasochistic themes. The international cut features some significant changes, and runs for 77 minutes. It was released theatrically as What! and Night Is the Phantom in the United States and United Kingdom, respectively.
