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.
