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
Starring: Cary Grant, Tony Curtis, Dina Merrill, Joan O'Brien
Revealing mistake: During the opening credits, as a crab descends past the periscope, the string attached to the crab is visible.
Lt. Cmdr Matt T. Serman: Sir, Sea Tiger was built to fight. She deserves a better epitaph than 'Commissioned 1940, sunk 1941, engagements none, shots fired none.' Now, you can't let it go that way. That's like a beautiful woman dying an old maid, if you know what I mean by old maid.
Capt. J.B. Henderson: Did you ever sell used cars?
Lt. Cmdr. Matt T.Sherman: No, Sir.
Capt. J.B. Henderson: I've got a hunch you missed your calling.
Trivia: Operation Petticoat was filmed at the US Naval Base in Key West Fla. They actually did paint a submarine pink. I was attending the Fleet Sonar School on the base at the time and watched with great interest. The submarine used was the U.S.S. Balao (SS-285), which was still in commission at the time.
