Continuity mistake: A sailor goes out on the luau covered deck to get his guitar, during an air raid. He lays down while a Zero strafes the deck hitting his guitar, which goes flying into the air toward the camera and lands about 10 feet from the sailor. In the next shot, the sailor kneels up and grabs his guitar which has appeared right next to him.
Continuity mistake: After the air raid and the pink sub starts to submerge, there is a good shot of a Zero flying over the sub. You can get a good view of the bottom of the Zero and can see it doesn't have bombs or bomb racks. Yet, after it passes, there is a bomb explosion near the sub.
Factual error: When Chief Tostin and Major Heywood are arguing in the engine room, Tostin says "I'm a machinist's mate, not a laundry feeler!" Actually, his rating would have been motor machinist's mate (later changed to engineman); machinist's mates work with steam propulsion plants, not diesel engines.
Continuity mistake: At the end of the movie, Tony Curtis and family arrive in a yellow taxi cab because Grant's wife didn't arrive to bring them. He tells the cab to wait and drive his family back. Then Cary Grant's wife comes flying up in her car, slams on her brakes and slides into the rear of the cab and knocks it into the bus. When the bus pulls off, the cab is attached to it...but it's now black.
Factual error: Lt. Holden and his men raid a warehouse on the night of 10 December 1941. When Holden is confronted by an MP, he explains his blackened face by saying it was a directive from Admiral Nimitz. However, at the time, Admiral Kimmel was in command of the Pacific Fleet. Nimitz was Chief of the Bureau of Navigation in Washington, and did not replace Kimmel until 17 December.
