Character mistake: At the end of the movie, when Tony Curtis goes aboard Sea Tiger, the word is passed, "Attention on deck." Since he is the captain, the proper announcement would be, "Sea Tiger arriving."
Operation Petticoat (1959)
1 character mistake - chronological order
Directed by: Blake Edwards

Revealing mistake: During the opening credits, as a crab descends past the periscope, the string attached to the crab is visible.
Chief Mechanic's Mate Sam Tostin: I'm a religious man, Captain, and I believe we'll get through if the Good Lord puts His mind to it. Of course, He'll have to give us His undivided attention.
Trivia: The initial premise of the movie, that the nearly-new U.S.S. Sea Tiger was sunk pierside at Cavite on 10 December 1941, then hastily repaired, is based on fact. A nearly-new American submarine was indeed sunk pierside at Cavite on 10 December 1941. Unfortunately, the real-life submarine could not be repaired in time, and had to be blown up. Her name was U.S.S. Sea Lion (SS-195).
