Continuity mistake: During the arrival to the island there are 11 choppers. The first time Kong appears he takes down two. In the next sequence where they all see him for the first time 11 choppers still fly by Kong. (00:30:40)
Continuity mistake: When the group has just encountered Kong, a visually dramatic scene shows Kong silhouetted against a deep orange setting sun. Yet immediately before and immediately after the scene, the sun is high in the sky and it does not get dark for what would be several hours in the movie timeline. (00:31:50)luvlethalwhites
Continuity mistake: When Col Packard is introduced, one can see on the left side of the desk behind him a wooden object beside a picture. In the next shot that object moves to the right behind the radio, only to return to the picture in the following shot. And it moves after this shot again behind the radio, and then stays there. (00:10:00 - 00:11:00)
Continuity mistake: When Col Packard shoots the "ugly bird" he is aiming left handed but after he shoots he is holding the weapon right handed.
Continuity mistake: When Weaver is on the top of the rocks to fire the flare gun to signal the boat, she is wearing her camera/tote bag around her and you can see it on her when she fires the flare at the skull crawler but when she is knocked off the rocks and falls backwards into the water, she isn't wearing the bag.
