After his surrealist masterpieces "Andalousian Dog" and "Golden Age", Buñuel turned to social realism with his rough film that documents the poverty of the Las Hurdes peasants. The plain images of the peasants documented the hunger and suffering with such power that the film was banned in Spain and Buñuel could not shoot another film in his country for 29 years, until he made Viridiana. Most critics interpreted the film only as a work depicting the neglection of the peasants with plain but striking language. This was true. But while doing this Buñuel also had in mind a critic of the documentary form an attack towards the urbanites who were to be its spectators. Buñuel quite consciously, was narrating the state of people in an unfamiliar land with the insensitive voice of a stranger and used Brahms' music, which felt quite out of place throughout the film. Only intellectuals could catch the parody of Flaherty's famed documentary "Nanook of the North", in the very last scene of the film. The communist and surrealist poet Pierre Unik joined Buñuel during the shooting and later narrated the film. The text of the film is an excellent example of how a language could be elevated through surrealist teachings. The director surprised the spectators by underlining the helplessness of the crew in the face of suffering people by editing it like a feature film. There is no doubt that Buñuel was deeply affected by and concerned about the poverty of the Las Hurdes peasants, but his real invention was to disturb the spectators who were to watch these horrible images in a setting intended for entertainment.
