The Caine Mutiny (1954) - 6 mistakes

Continuity: When Capt. Queeg has his first meeting with his officers a message comes in. When Queeg asks the messenger for his name and rank his right arm is on or under the table in alternating shots.

Factual error: In the shot where the three officers ride the aircraft elevator from the hangar deck to the flight deck after arriving aboard the admiral's carrier, you can briefly see some of the aircraft parked on the hangar deck, and they are jet aircraft. The aircraft have pointed noses, no propellers, and the fuselage shape and markings are consistent with first generation Navy carrier jets. These types were not in service until the mid-50s (See "Bridges of Toko-Ri").

Continuity: When Queeg orders a safety drill on the ship there are two seamen without a helmet. One helmet is being handed through to them, but in the next shot both men are wearing helmets. That Queeg, who should have seen both, wants to punish only one makes this slip complete.

Continuity: In the scene at Yosemite where Keith is waiting for May to have breakfast there is a big silver pot on the table. After May arrives the pot isn't there anymore.

Continuity: Following being dragged in the ocean attempting to secure a tow-line, Van Johnson immediately appears on deck, soaking wet, naturally, except for the back of his left shirt sleeve, which is amazingly dry.

Factual error: The movie takes place during WW-II. In the scene where Maryk, Keefer and Keith go to visit the admiral on the aircraft carrier, the ship has the hull number of "33". The aircraft carrier USS Kearsarge CV-33 was not commissioned until 1946, after WW-II was already over.
