Nah… it has always been called:
But no one ever remembers the part below ‘The Thing’ they always just remember it as ‘The Thing’. The original short story was called ‘Who goes there?’ which the remake stayed far closer to.
Trivia- James Arness played the monster (aka 'The Killer Carrot)
The reason some of the scares looked so good was because the director was real trickster (though some thought he was an SOB), he would tell the actors to say their lines and then open a door and go outside. What he didn’t tell them was that James Arness would be standing outside waiting for them, to give them the fright of their lives!
Twilight? heh…just kidding.
