Trivia: The TV edit of this film includes lots of footage that was purposely left on the cutting room floor, such as when the dead Norwegian on the table blinks, and so on. The TV edit also has narration. This version is edited so much that director John Carpenter has publicly stated that he finds the TV edit embarrassing and a disgrace to his movie.
Trivia: In the scene after Macready visits the Norwegian base, he is explaining what he saw to everyone. Childs questions what he says calling it voodoo, while Palmer says "Chariots of the Gods, man. They practically taught the Mayans everything they knew." This is in reference to Eric Von Daniken's 1968 book Chariot of the Gods, about ancient aliens being the catalyst for our modern world.
