The movie The Thing by John Carpenter has been read by the director himself as being a kind of allegory for the strange disease that was making the rounds at the time of the film's release, 1984, a disease which was to later become known as AIDS.
I have another reading of the film based on what John Carpenter himself says is the key exchange in the film
"I don't know who to trust anymore."
"Trust is a hard thing to come by these days. Why don't you trust in the Lord?"The story of the film revolves around a human and animal-mimicking alien life form with hostile intentions which hides in plain sight behind a fake appearance in order to conceal its true ugly self.
The paranoia that sets in is of course inevitable as it is impossible to tell who in your entourage is the hostile alien which will kill and come to imitate your physical appearance the moment you're alone with and turn your back on it.
In my view this is a great allegory for the disease of psychopathy because psychopaths mimic human emotion and feelings, seduce people with their glib, surface charm only to prey on and destroy them when the occasion arises.
It is indeed very hard to tell who is a psychopath and what hostile life form may be lurking under casual passers-by on the street, someone closer to home or even in the public eye (such as Jimmy Saville). People who've been victimised by psychopathic individuals in their lives will of course develop trust issues as does the character Blair in the film (well named as it turns out, the script foreshadowing in its own way the rise to power of dubious, untrustworthy politician Tony Blair).
Furthermore, as psychopathy researcher Thomas Sheridan has argued, psychopaths aren't really human as they lack a normal human emotional centre and are truly 'other' to you or me since completely devoid of heart consciousness and the conscience that comes with the latter.
It is the disease and oddness of psychopathy that has made researcher Mark Passio sympathetically consider 'intervention' theories in human origins, i.e. that we were fashioned by a non-human intelligence to serve as a slave labour force and that these aliens did such a botched job in the development of our species that psychopathy was one of the many anomalies present in the original human genome.
These 'intervention' theories - as opposed to more fashionable 'evolutionary' theories - are based on texts and artefacts going back to ancient Sumer which was located in present day Iraq and which seem to indicate extra-terrestrial interactions with humans, including in their coming to exist and in the origin of occult Mystery Traditions, as these (immoral) beings taught us knowledge about the universe in symbolic ways.
The movie Alien v Predator points to such extra-terrestrial lore in its very plot according to which the Predator aliens were gods to us humans and the serpentine xenomorphs were there to provide a rite of passage for said gods.
All that being said reptile-brain-based psychopathy gives some credit to reptilian conspiracies as does the presence of evil lizard-like creatures in ancient and modern popular culture (this reminds me that I once saw an old Dr Who episode with a reptilian alien able to control people's minds).
What can be drawn from all this is the lesson many have now learnt, that many Hollywood films have a dumbed down plot that most can follow, which is their exoteric content, and a more hidden, esoteric content that will only be garnered and understood by those who are clued up as to alternative history and explanations.
John Carpenter of course went on to make the movie They Live which explicitly suggests alien interference at the very top as well as in all the mainstream facets of human society.
