each of them sees the others as a potential Thing.
Except the one that is The Thing, who has got to be thinking "humans are idiots!".
Makes sense in that context, and adds a little more wiggle room for movie suggestions. Given your new information I'd add "They Live" to the list. It doesn't necessarily deal with impregnation/infestation (unless you count an invasion as an infestation), but it is about turning people in to puppets using mind control which could be seen as a sort of "corruption".
