Revealing mistake: When MacReady burns the one "Thing" with the split head, in one shot it walks by MacReady in the foreground, and you can tell in that shot that it is just a still dummy burning, as it isn't moving at all. It just sort of floats past with its arms at its sides, while in the previous and next shots it is wildly moving around, arms flailing.
The Thing (1982)
1 revealing mistake - chronological order
Directed by: John Carpenter
Starring: Kurt Russell, Keith David, Wilford Brimley, David Clennon, T.K. Carter
Character mistake: When MacReady is giving the blood test, the scalpel they are using is not properly sterilized after each person cuts themselves (shown when Nauls cuts himself, then when Windows goes next: all he does is wipe the scalpel on his pants). Using the same scalpel seems like an extremely stupid thing to do as Fuchs told MacReady that even a small particle of the Thing could take over a person. (01:19:55)
Clark: I dunno what the hell's in there, but it's weird and pissed off, whatever it is.
Trivia: The ruins of the American and Norwegian camps are actually the same set. Carpenter saved $750,000 by only filming the one set with different lighting rather than building a second one.
Question: Was any member of the team aware that they were infected by the creature, or did they not know they were until they began changing?
Answer: The death of Fuchs is probably the best answer to this question, as it appeared that Fuchs burned himself alive before the Thing could assimilate him. It's also possible that Norris suspected he was infected before he transformed. There is a scene in which we see Norris, who is alone, suddenly wince in pain, surprised, and grab at his chest, but he continues functioning normally thereafter. Following the altercation with Mac, Norris collapses and becomes unresponsive, until his chest cracks wide open and bites off Copper's arms. Also, in the blood test scene, Palmer's facial expressions appear to betray his secret, but he was already fully transformed at that point.
