Salt of the Earth (1954) is the revenge of a group of blacklisted directors, screenwriters, and actors on McCarthyism and Hollywood, a low-budget film based on a 1951 strike against the Empire Zinc Company in Grant County, New Mexico, in which most of the strikers were Mexican-Americans. Only a few professional actors appear in the film; the rest are the actual miners from the strike and their families. The film is notable for its feminist social and political point of view, highly unusual for the 1950s.
