Factual error: In the cemetery, the skeleton of Gregory Peck's son is far too big to be that of a newborn, which it is supposed to be.
Factual error: The train consists of nine cars - six RIC cars of the Swiss Federal Railways (two 1st class with nine compartments each, two 2nd class with eleven compartments each, one 2nd class with twelve compartments, and one dining car between the classes), an MU sleeping car belonging to the CIWL (International Dining And Sleeping Car Company) between the two first class coaches, and at each end one older Swiss baggage car. The first class has 108 seats, the second class has 204 seats, and the sleeping car has 36 berths; so the train has space for 348 passengers - or 400, adding the 52 restaurant places. I wonder where they put 1,000 people on this train.
Factual error: The fact that the respiration of a single animal - however large - could lead to an increase in the level of carbon dioxide in the local area is so absurd it is laughable. Carbon dioxide exhalation is part of a closed loop cycle and the CO2 exhaled by Kong would be matched by the CO2 taken in by the plants growing on the island. It cannot be otherwise. Elevated levels of carbon dioxide are incredibly dangerous and any animal living on the island - including Kong - would suffer if things got out of kilter.
Factual error: In the DVD theatrical trailer for "Carrie," Stephen King's name is misspelled. It is spelled "Steven".
Factual error: When Richard Kiel is shooting at Gene Wilder on the train, you hear the "ping" of a "silencer" on the gun. However, Kiel is shooting a .357 magnum, which cannot be equipped with a silencer.
Factual error: When Harry shoots the last badguy in the tower with a LAW, the safety of the weapon is still on. The pin to arm it has to be pulled out. If it were armed, you would see a little pin, instead of little block, between Harry's little finger and his ringfinger. (01:28:35)
Factual error: In the scene where Julie, the secretary, has been discovered dead; the lieutenant approaches her, kneels down, and checks for a pulse with his thumb. As anyone with any medical knowledge should know, if you attempt to take someone's pulse with your thumb, you will get your own pulse and not the victim's.
Factual error: When a Rear Admiral and Captain are walking together, the Captain's epaulets are the wrong way round. A cardinal sin in the Navy. (01:30:00)
