Character mistake: While General Patton is in Malta as a decoy for a fake Greek invasion, he gives some aides a tour of the fortifications there and tells them that they were "defended by 400 Knights of Malta and 800 mercenaries against a force of 40,000 Turks." He is referring to the Siege of Malta in 1565, but the date he gives is 1528.
Character mistake: Immediately before the attack, when the flag is being raised on the flagpole, the young seaman who previously rang the bell steps backwards and trips over the concrete step behind him.
Character mistake: When Dean Martin is telling passengers the flight plan, he mentions Toronto, Montreal, Cape Race and Saint John, Newfoundland. However, Saint John is in New Brunswick. St. John's is in Newfoundland. (01:11:15)
