Abstract
This article from Neues
  Deutschland, the official daily newspaper of the Socialist Unity
  Party of Germany (SED), continued the East German tradition of
  associating West Germany with fascism and Nazism, seizing upon a
  controversy caused by the attempt by the West German embassy in France
  to have the French documentary Night and
  Fog withdrawn from the Cannes film festival. The film documented
  the horrors of the concentration camps and also showed the
  participation of the Vichy regime in Nazi crimes. Contrary to claims
  made in the article, the film was not withdrawn from the festival,
  however, it was shown out of competition. The film was directed by
  Alain Resnais, a French avant-garde filmmaker; he insisted on making
  the film with people who had been directly affected by the Holocaust,
  as he felt that he could not do justice to the event himself. He
  worked with Jean Cayrol, a French novelist and poet who spent three
  years in a concentration camp after participating in the French
  Resistance, who wrote the narration for the film, and Hanns Eisler, an
  Austrian composer who had gone into exile after his music was banned
  by the Nazi party, who composed the score. Eisler was a lifelong
  communist; he emigrated to the United States in 1938 but was
  blacklisted by the House Committee on Un-American Activities and
  eventually deported in 1948—he returned to Austria, but later moved to
  East Berlin, and is most well-known for composing the national anthem
  of East Germany. The film was show in East Germany during Leipzig Film
  Week in November 1956, but the state film company DEFA claimed that
  the West German version of the film had been mistranslated; they
  created their own translation that suited the communist ideals of East
  Germany better, thus the film was misused by the very people who were
  accusing West Germany of misusing and suppressing the film.
