Read this article at IMDB and this one about the lawsuit that Terminator 2 borrowed heavily from another script, “The Minotaur.”
I don’t suppose anybody would have a copy of the script or know where one is? I’m curious about making the comparison myself. Apparently, “The Minotaur” contains a story about a liquid machine that morphs into different people and makes its fingers and arms into pointy metal weapons.
(Doing some research, I found this story goes back to 1993:
