Character mistake: At the end, as Kenneth More and Dana Wynter emerge from the command centre, they are surprised to find that it is 9 AM, not 9 PM. Since all military and naval forces use a 24-hour clock, they would have known that the time was 0900, not 2100.
Sink the Bismarck (1960)
1 character mistake - chronological order
Directed by: Lewis Gilbert
Starring: Kenneth More, Laurence Naismith, Dana Wynter, Carl Mohner
Factual error: The battle of the Denmark Strait is wrong in that both sides are heading and shooting in the wrong direction. The Germans are shooting to starboard rather than port, and the British are shooting to port rather than starboard.
A.C.N.S.: Good old hood, she'll get them.
Trivia: Esmond P. Knight, the actor who portrayed Captain Leach of the battleship "Prince of Wales" was a crew member on the ship during the real battle where he was badly injured, suffering a period of blindness.
