King Kong (1976)

Factual error: When the Petrox engineers dump Kong into the pit filled with chloroform they haven't knocked him out - they've killed him. Chloroform vapour is heavier than air so Kong is breathing it in a pretty pure form - and it is lethal in concentrations as low as 40,000 parts per million. In the time it would take to render a gorilla unconscious by this method, it would die. This ignores the fact that liquid chloroform is a severe irritant and a contact poison, and its breakdown products include phosgene and hydrogen chloride, both deadly poisons. They might as well save themselves some time and use that dinky little bulldozer to fill in the pit.

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?
