Carry on Cleo (1964)
Two Britons—inventor Hengist Pod, and Horse, a brave and cunning fighter—are captured and enslaved by invading Romans and taken to Rome. One of their first encounters in Rome leaves Hengist being mistaken for a fighter, and gets drafted into the Royal Guard to protect Cleopatra.
