An Alien invasion movie is an aspect of science fiction movies where other lifeforms from different planet come to earth to enslave, harvest beings for food, steal the planet’s resources or to destroy human life. They were popular in the 1950’s due to the use of special effects and creative story. Many of the science fiction movies introduced incidental emotions of concern and tension about the Communist invasion of America and a chance of a nuclear holocaust. This terror was presented in various aspects, such as scientists trying to create a dangerous experiment often led to horrific mutant released, radiation’s dreadful result on a living being, aliens manipulating humans using mind control. Movie makers and the producer of science fiction genre were normally left alone by the government and the private groups that prevented the assessment of the country’s policies.Talks about the progress of atomic weapons and possible effects were restrained in another genre and the public debates, however, it could be told through the stories. In most of the science fiction movies, it indulged the public’s fear about the nuclear bombs and communism. If details in interpretations vary, most accept that the film is, at least in large part, an allegory for the loss of individual autonomy. What’s perhaps most curious is that Invasion of the Body Snatchers’ supposed metaphorical message has been associated to both ends of the political spectrum: some have read the film as a reflection of right-wing paranoia about Communists taking over the American way of life, while others see it as symbolic of left-wing paranoia about McCarthyism. It is natural to read what we know of the 1950s into the film: national rhetoric at that time was steeped in anti-communist obsession, and many Americans feared being overtaken by an outside force intent on uniformity. Body Snatchers is easily read as a call to fight back against the mindless conformity of mass society and the soulless aliens who have dialogue like, “Join us – life will be much simpler and better.” The general small-town America setting of the film could easily be anyone’s hometown within the country; thus its image feels distinctly American, rather than belonging to any specific region, and takes on a symbolic resonance for the country as a whole. But while the film is undeniably a portrait of individualism in the contest, challenging our national identity and humanity, the social target or political affiliation of the film, if it has any, is not finally clear.The opening scene of the movie establishes the protagonist, Miles Bennell, to the audience and through him, the audience observes the movement of the growing ‘pod-people’ the antagonists, shown only through Miles point of view and established the threat at the center of its conflict. The narrative is orchestrated to imply that Miles is really irrational to his dismay and what the audience is witnessing isn’t really happening.This can be seen in the last scene as Miles gravely tries to alert other humans of the upcoming invasion. Miles is now the minority he is trying to warn the locals but to his dismay, he is ignored and thought to be a crazy person. The hero and the villain have had their parts switched, so how can Miles be linked with the simple people of the town. it draws a comparison with the paranoia and subsequent conformism of 1950s America in the face of McCarthyism at the time of production on this film. The scene in question suggests that the non-conformist in Miles, unwilling to shed his individuality for a cause he doesn’t believe in, will be reduced to a small voice in a crowd of thousands. The hero’s love interest is one of them now. This was the reality for many people, especially in the Hollywood film industry at the time; he will be silenced by the deafening voice of the new majority, including people they once held dear.
