King Kong (1976)

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.

Jack Prescott: There is a girl out there who might be running for her life from some gigantic turned-on ape.

Trivia: Fay Wray, who had played Ann Darrow in the 1933 version of King Kong, was offered a cameo in this movie. Wray refused, because she hated the script.

Question: When Long let Dwan fall into the water, we see that the water she plunged into is pretty deep. How deep was the waterfall when she fell in?
