Revealing: In the last third of the film after Kong has broken through the gate and is rampaging through the village, a native jumps out of his hut, loses his balance and falls by a chicken coop. His wig comes off and gets caught on the fence.

Revealing: The figures dropping from Kong's cliff into the river are obviously limp dummies.

Revealing: When Kong breaks through the giant doors towards the islanders, part of the doors become transparent and you can see Kong's leg. This is a result of the matting special effects used.

Revealing: When Kong crushes the scaffolding in the island village, it collapses not into a heap of splinters but in a neat panel of solidly bound wood.

Factual error: There are just a couple of things wrong about the gas grenades used in the movie: gas grenades do not explode, they spray their contents; and second: if the gas really is that powerful, it should be used with more caution; a simple sudden downwind breeze into an uncontrollable gas cloud, and the users would become their own victims.

Revealing: As the men walk past the downed stegosaurus, the camera moves faster than they do (judging from the background) but they stay at the center of the screen. Obviously the camera on the model of the stegosaurus moved faster than the camera on the men.

Continuity: When Driscoll is hiding in the cliff cave with Kong above him, he moves from the front of the cave to the back two or three times without ever moving from the back of the cave to the front.

Audio problem: In the early stages of Kong's fight with the Tyrannosaur, Kong throws two (nonconsecutive) standing punches that don't hit but make noise anyway.

Factual error: A creature of Kong's size would not be taken out that easily with the gas grenade as in the movie, for: 1) it explodes far too low for the gas to affect him; 2) even if the gas had reached his breathing organs, it would have taken more and prolonged exposure to knock him out.

Revealing: As one plane swoops at King Kong on the Empire State Building, another flies behind his head that is much larger than it should be relative to him.

Continuity: Just before Kong is gassed and captured, he picks up a native and bites his head. In a close up, he has the native by the legs, then in the long shot he is biting the native's head.
