Je suis d'accord, c'est très fortement inspiré du "space jockey" et je trouve que l'une des forces des films est de ne jamais montrer la forme réelle d'un alien, ce qui les rend un peu plus "réaliste" à mon goût.
J'ai lu la nouvelle originale et elle n'est pas mal du tout, si on garde en tête qu'elle a été écrite dans les années 40 :
Au passage, le Wiki consacré à The Thing contient des informatons au sujet de scènes abandonnées du film original :
The Snow Things are a pair of Thing Beasts created through the two last sled dogs that survived the attack from the Kennel Thing. They were originally intended to be used in the 1982 film, however due to lack of time and money, they were ultimately cut.
The scene they were supposed to be in involves the two remaining sled dogs after the Kennel Thing attack, instead of being killed by Blair, the script has the remaining sled dogs being assimilated by the pieces of the Thing which they had bitten off during the kennel fight. They subsequently escape from the kennel and start hightailing it to the Antarctic coastline. Upon discovering the dogs are missing, MacReady, Childs, and Bennings take off after them on snowmobiles.
This scene turns out to be one of three possible deaths for Bennings: his death we see in the film, getting murdered in the kennel (of which we see a partial clip on the DVD, see more below), and this scene on the ice field that was never filmed. Here, Bennings gets pulled to his doom underneath the ice by one of the Dog Beasts. Their appearance quite differs the ones featured in the game, their appearance resembles a giant hairball and a tentacle with mouth as shown in the concept art of the unused scene. Although despite this, they were featured in Alan Dean Foster's novelization of the film with the sequence that was featured in Lancaster's second draft of the screenplay.
