Continuity: When the sound engineer says "We're gonna have the ship's engines all over the dialogues", he has his left hand to his headphones. When it cuts his hand is gone, but in the next shot his hand is back on the headphones.

Factual error: In the scene in which Kong is running loose on the streets of New York city, and being chased by two military Army vehicles, the vehicle identification number, starting "USA and followed by six or seven numbers" is visible on the hood of the vehicles. The first two numbers in a USA number is the year of manufacture of the vehicle. Thus, the truck with the 3 inch cannon was manufactured in 1945 because the number starts "USA45." The time setting of the movie is 1933-1934.

Continuity: When Carl steps out of the room after screening his movie he doesn't cast any shadow on the door behind him. When it cuts his shadow suddenly appear on the door.

Continuity: In the scene where the movie star is trying to talk them into giving up he has a rope slung around his chest over one shoulder. He never takes it off, but when he leaves he no longer has it, and Adrian Brody is holding it.

Continuity: When Kong is about to fight the last Rex, Ann begins to back under his arms. In a distance shot we see that she is already a fair distance behind his arms, underneath him. Cut to Kong noticing this, then cut back to a back shot of Ann backing under and she has not even reached his arms yet.

Revealing: When the longnecks are tumbling down the hill it's obvious there's a screen behind Preston and Jimmy and Hayes.

Continuity: When Kong has grabbed Hayes, he tells the rest of them to get out of there. As he says "Do as I say", his gun is pointing at Kong. When it cuts he suddenly has his other hand on the gun cocking it.

Continuity: While telling Carl about the shipwreck sailor the crew of the venture picked up on an earlier cruise, Lumpy keeps whittling on a piece of scrimshaw. He continues to do so when Carl is about to leave the galley. In the next shot, when Carl turns back to give a reply, Lumpy's arms are suddenly lowered at his side.

Continuity: After Ann and Carl arrive at the docks, as she stands beside the Venture her coat collar is flipped up, then turned down and back up between shots.

Continuity: In the scene where the boat is leaving NYC and the camera is panning around it - the smoke from the ship "follows" the camera by always pointing to the right relative to the camera view; even though it should be trailing backwards, opposite of the ship's direction.

Plot hole: In the scene where Ann is laying/sleeping with Kong on the cliff, her dress should not only be beyond filthy, but it should be tattered and shredded. It doesn't so much as have a thread out of place after being carried so violently through the jungle and being caught between Kong and the dinosaur. Also, she at this point has been in Kong's possession for several hours to a day or so, and not once has she even shown any signs of hunger, thirst, or the need to relieve herself.

Continuity: In the scene where Ann is unconscious, Kong puts Ann on the ground and she is lying on her arms. When it cuts to the shot when he begins poking her, one of her arms is stretched out.

Visible crew/equipment: As one of the Venture crew members picks up a chloroform bottle from a case, you can see a bright studio spotlight reflected in the bottle.

Continuity: When Ann is about to steal the apple, she picks up a different apple first. When she is about to put it back, the angle of the apple in her hand changes. Watch the apple stalk and you can see it.

Continuity: When Ann is caught stealing the apple, Carl pulls up a coin saying "Excuse me. Ma'am, I think you dropped this". The way he holds the coin differs in the next shot.

Continuity: During the whole film, even though Ann is thrown about and man-handled by Kong, as well as sliding down rock and cliffs, and falling over numerous times to escape the many creatures and dinosaurs, she ends up with virtually no marks or scratches on her body. Her dress is dirty, but that is about it. Her hair also stays reasonably in place. Surely she would have been scratched and bruised all over her legs and arms from the trauma.

Continuity: Jack and Carl are in Carl's stateroom. Carl opens the crate of whiskey, takes out a bottle and puts it down. The bottle then turns itself around so the label's sometimes visible, sometimes not.

Continuity: When Ann and Kong are on top of the Empire State Building near the very end, he sets her down on top as he grows weaker. She begins to stand, pulling herself up on his fingers, the shot cuts and she is standing but his hand is now out of place back towards his body, not near Ann where it should be.
