The paranoia and uncertainty in John Carpenter's The Thing (1982) is so well constructed that there is still no consensus on who gets infected, or even when some people do. The thing I really like about it is that the creators may not have actually had a definitive answer in mind themselves, but we should be able to interpret the most likely sequence of events using in-world and real-world logic. The FAQs at this fansite and IMDB do a great job of presenting some theories and explanations. The thing is, the question-answer format makes it a bit hard to follow the events as the movie unfolds.
Are there any timelines available (or could they be made) that chart the different theories of the infection spreading through the crew? For when I inevitably watch the film again.
