The period of 1950’s in America was era which changed the views on a certain issues and interpretation of these issues of american people. With the rise of communism, suspicion of spies in government and visions on space exploration, American civilians were introduced to number of unexplored and unexplained inside story of unknown terrene for them. I think invasion of body snatchers perfectly describes the situation of the american people in that era by taking concepts of real spies in government, Russian space exploration and results of fears aroused by HUAC to a very abstract concept of alien invasion on the world. Film is metaphor of america in 1950s, since it parallelizes the theme of mccarthyism spread of communism and cold war
