In
Who Goes There?, the Thing is discovered by a team of
Antarctic scientists frozen in its spaceship, which had crashed on Earth 20,000,000 years before. After it thaws, it kills and takes the form of the team's physicist, Connant, unbeknownst to the others. It uses its leftover body mass to transform into a sled dog. The team discovers the dog-Thing and kill it as it is transforming. The pathologist of the crew, Blair, goes insane with guilt as he was the one who had lobbied to thaw the Thing. He vows to kill everyone at the research station in order to save mankind from the Thing, and is locked in a cabin. The crew destroy their vehicles in order to isolate the base, but pretend that everything is fine in radio transmissions in order to prevent rescue attempts. The crew attempts to discover who among them may have been assimilated and replaced by the Thing in order to kill the imitations before they escape. In a
blood test, they discover that either Doctor Copper or commander Gary is an imitation, but the result is inconclusive. Assistant commander McReady (known as
R. J. MacReady in the 1982 film) takes over the crew and determines that all the animals at the station, except for the dog used for the blood test, have become imitations. As such, the crew kills all of them and burns their bodies. By this point, the entire crew suspects one another, and the men begin to go mad wondering if they are the last human left, or if they would be able to tell if they were themselves not human. After the cook, Kinner, is murdered and revealed to be the Thing, McReady discovers that every part of the Thing functions as an individual organism. He then uses this fact to test each surviving crew member by dipping a hot wire into samples of their blood. When a blood sample recoils from the heat, the owner is instantly killed. Fourteen crew members are revealed to be the Thing and are killed. The remaining men go to test Blair, who is still isolated in the cabin, and discover that he had already been converted. After McReady destroys the Thing with a blowtorch, it is revealed that it had almost completed building a
nuclear-powered anti-gravity device that would have allowed it to escape to the outside world. ==Production history==
