American officials and the American public began to believe that the Soviet Union was bent on building a Communist empire and that it would halt its expansion only when forced to do so.
With this conviction, the American government took steps to block further Soviet expansion. From then on, relations between the two powers bordered on a state of war….
The Red Scare after World War II … had roots not only in the cold war but in long-buried currents of anti-intellectualism and in the rapid social changes attendant on the shift from depression to prosperity. …
Much of what was widely believed during the scare was nonsense. There was a notion, for example, that large numbers of Communists had infiltrated the American government. … There was another notion that large numbers of Communists had infiltrated the news media, the motion picture industry, and the clergy, so that news, movies and sermons had gulled the public into approving pro-Communist policies. These beliefs rested on the fantasy that the United States, if it chose, could shape the world to its will, and that, whenever anything went wrong, the fault had to lie at home.
—Ernest May, Anxiety and Affluence, 1945-1965
The wave of anti-intellectualism crested with McCarthy and washed over much of the remainder of the decade. Blacklisting had become such a threat that many filmmakers consciously made openly anti-Communist films, to preserve their reputations and obtain favors. Red Paranoia was so widespread that many more filmmakers reflected the fear of subversion and infiltration in their movies, even unconsciously. In either case, the monster movies of the Fifties in general reflect an intense fear of infiltration and dehumanization by a subversive, colonizing power (Invasion of the Body Snatchers, The Brain Eaters) or by a communal society bent on destructive expansionism (Them!, War of the Worlds). Creeping Communism became one of the main themes of monster movies in 1954, and the monster movies themselves became one of the main proponents of the battle against Communist ideology (or what was generally understood to be such). Its metaphors were monsters, from outer space, from under the earth or on it, bent on conquering the human race (always starting with the United States of America), and often determined to create a mindless Utopia devoid of feelings and individuality.
