Factual error: Cadence arrives for the wedding on a 727. Closer examination of the aircraft's livery reveals it is a Kitty Hawk Airlines aircraft. This would be fine were Cadence air freight, as Kitty Hawk is a cargo airline. (00:28:40)
Factual error: Early in the movie we see the newspaper dated "Sunday, March 14, 1987". March 14, 1987 was a Saturday, not a Sunday.

Factual error: At the end of the movie the cast is counting down to the explosion of the Krell furnaces. They reach zero and the furnaces explode. They see the light from the explosion just it happens. But they are 100 million miles out by then. The light would have taken over 8 minutes, about as long as light from the sun takes to reach earth, to reach the ship.
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.
