But coz the ending of the movie was so open-ended people have been making their own judgements about what really happened. Popular theories around the Internet are:
Theory one: MacReady is "the thing"
Apparently in the video game
The Thing (Universal Interactive), where the story follows a military rescue team sent into the frozen wastelands of the Antarctic to investigate the deaths of the team it apparently shows that Childs body is found in the snow but not MacReady's and in the end it is implied that MacReady is the Thing.
I haven't actually played the game so I can't comment really on the validity of the theory- but heck the game looks pretty darn good and id like to play it - But anyway, yeah you could say its just a video game and doesn't have to have any significance on the actual outcome of the film itself. But then the tagline for the game is "where the movie ended, your mission begins." - hmmm.
In the movie however we basically follow MacReady's every move after the group testing except for the bit at the end where it could have in fact been some hours after the last battle with the imitations, where we see him walking in the snow wrapped in blankets. Maybe he was imitated in that period? Or maybe the blood tests earlier on were switched?
Theory two: Childs is "the thing" due to lack of breathing.
See above for my previous post.
Also: Childs has been missing for several hours and has miraculously survived the attacks. Bit suss ey? Further on this apparently due to the request of the studio, an alternate ending was filmed for the movie, and in this ending MacReady is the only survivor and he returned to "civilisation" and was tested for being “the thing” and came out negative. However, the ending was rejected. (I wonder why

).
Theory three: Both men are "the thing"
If they were both imitations why are they sitting around having chitchat and not looking for a way to escape?
Theory four: Neither man is "The Thing" and are both left to die

self explanatory really. Although apparently good times were had: Loads of drinking
Theory five: a Dog is the Thing
In the TV version of the film apparently we see a dog trotting off in the snow as the last scene of the movie…
In my opinion: I think it was an awesome film. I like the fact that we just bloody don't know what happens and as was said above in another post the viewer feels paranoid. I can see some truth in how each theory could be possible but how can anyone be sure really?
