Body Snatchers: Parasitic Monsters in Film

What is a Body Snatcher?

TV Tropes defines a body snatcher as "a foreign intelligence that takes over a person's body". Hosts for body snatchers tend to act out violently, and often undergo grotesque physical transformations. Body snatching is a common trend, particularly in the horror genre, and can take the form of possession, implantation of a fetus for incubation, or cloning, just to name a few types.

                                                                                                                            

What makes body snatchers such frightening monsters? 
As human beings, we are social animals that obligately seek out others to form groups. The introduction of a body snatcher impedes one's ability to trust others, and forces individuals to self-isolate for their preservation of self. Body snatchers are manifestations of our fear of losing our identity in a world with such strict social mores.
