Jupiter's Darling is a swimming movie and a musical romance film released by MGM in 1955 and directed by George Sidney. It starred Esther Williams as the Roman woman Amytis, Howard Keel as Hannibal, the Carthaginian military commander and George Sanders as Fabius Maximus, Amytis's fiance. In the film, Amytis helps Hannibal swim the Tiber River to take a closer look at Rome's fortifications.
The film features many historical characters, including Roman generals Fabius Maximus and Scipio Africanus who appears briefly, in addition to Hannibal. Carthaginians Mago Barca and Maharbal also appear.
Jupiter's Darling was based on Robert E. Sherwood's anti-war comedy play The Road to Rome (1927).
The film was the last of three films Williams and Keel made together, the other two being Pagan Love Song (1950) and Texas Carnival (1951).
