Continuity: When the men arrive at the crash site and are looking it over, their shadows are always pointing away from us no matter whether we are looking at their faces or looking over their shoulders at the site.
Continuity: The length of the boards that the Thing breaks to confront the soldiers.
Continuity: Near the end of the film, when the Thing breaks through the door to confront the airmen for the last time, the wood planks that had been used to reinforce the door are broken off and dispersed. Then the camera quickly cuts to the airmen and then back to the Thing. Only now there is a new large piece of wood that appears next to the Thing, which he proceeds to pick up. This piece of wood was not there when he initially broke through the door.
Crew or equipment visible: As they fly over the crash site, you can see a small black squarish-object at the far right of the screen on the ice. This could be some piece of studio equipment, and it certainly doesn't belong there.
Factual errors: The block of ice that contains the Thing they chop out would have to weigh close to a ton, and therefore near-impossible to lift out of the ice, or have the dog sled move it easily, or lift it into the plane.
Continuity: In the credits there is a listing for "Lt. Ken Erikson," but he's introduced to the reporter as "Lieutenant MacPhearson, " and is continually referred to throughout the film as either "Mac" or MacPhearson.
Continuity: To force the "Thing" up on the wooden walkway, a tool is slid at him. He jumps. The tool is seen in different resting positions in the following shots.
Continuity: At the end, the co-pilot throws his tool to force the thing up on the walkway, but immediately after electrocuting the monster the co-pilot is seen holding the same instrument.
Continuity: Immediately after landing the plane at the camp, the apparently stationary left propeller moves between shots.
Continuity: When the airplane arrives from Anchorage, the camp is bathed in sunshine when seen from the air but the crew disembark in semi blizzard conditions.
Continuity: In the Officers' Club early in the movie, money disappears from the middle of the poker table between shots.
Continuity: When the C-47 transport first lands at the base, the plane comes to a halt, the propellers stop, the door opens, and the crew and passengers climb out. Not only is one of the propellers suddenly in a new position, but there is also a buildup of snow on the wing that was not there a moment before.
Errors made by characters (possibly deliberate errors by the filmmakers): Carrington describes the "Pliocene" human-ancestors as being primeval worm-like creatures. This description would be better suited to the Cambrian or Paleozoic times. In the time of Pliocene (Greek for "beginning of the recent"), recognizable man-like creatures were already showing up. The australopithecines came around during the later part of this time.
Revealing mistakes: In the scene during which a soldier mistakes the 'radioactive isotopes' in a storage room for signals being emitted from the Thing, an electrical wire providing electricity to the Geiger counter can clearly be seen coming out of his right pant leg.
Continuity: Towards the end of movie the Thing breaks down door and enters barracks and is doused with kerosene and lit on fire. As soon as fire is lit, it is obvious the stunt man is not only shorter, but he is wearing a bulky asbestos suit, not the tight one James Arness is wearing as the Thing.
Errors made by characters (possibly deliberate errors by the filmmakers): At the conclusion of the scene where Cap. Hendry first meets Dr. Carrington, as they are leaving the lab Carrington Refers to Nikki as "Miss Litton" rather than "Miss Nicholson." Margaret Sheridan's face registers her awareness of the actor's mistake, but she "goes along with it" and the scene was printed "as is" rather than give a retake.
Factual errors: The location being the North Pole, there would be no day/night cycles. Further, given the date of November 2 (from Dr. Carrington's log entry), the North Pole would be over a month and a half into a 6-month period of darkness.
Continuity: The creature runs away outside where it was fighting with the dogs. You can clearly see the right arm still attached to him. Seconds later they discover the arm under one of the dead dogs.
Factual errors: A C-47 twin engine cargo plane of that era could not have flown non-stop from Anchorage to the North Pole.
Revealing mistakes: When the crew blows up the flying saucer with the thermite charges, they duck down to the ground. While they're down, all the dogs are standing up like nothing has happened.
Revealing mistakes: When the crew is standing on the ice over the frozen, crashed saucer in freezing weather, they have dialog with one another, but at no time can you see anyone's breath.
Continuity: Early in the movie Tex is operating from the Radio Room with large windows clearly showing the snow. Later in the movie he states that the Radio Room has no windows.
Continuity: In the final confrontation with the Thing, Scotty is shown in the front line of the group with his camera raised to take a photo. In the next shot from behind, he is at the rear of the group.
Revealing mistakes: Towards the end of the movie, the team barricades The Thing in the mess room with wooden boards. When the creature finally emerges from the mess room for the final confrontation, the door swings inwards, towards the creature, obviously opened by James Arness. Therefore, the barricades, which would have prevented the door from being opened outwards, were useless.
Errors in geography: The captain states that he is navigating to the crash site near the north pole by steering toward "that peak ahead", and black mountains can be seen on the horizon in the scene of the crash site. There is no land closer to the north pole than Kaffeklubben island, 707 km (440 miles) from the pole.
Continuity: When the plane arrives at camp the sled dogs are aboard. But after landing only the crew and passengers debark and close the doors leaving the dogs aboard the plane.
