North Korea: The Parade (1989)

Defilada was made on the occasion of the 40th anniversary celebrations of state's founding in North Korea, which the regime intended to use to eclipse the 1988 Summer Olympics taking place that year in Seoul, South Korea. The North Korean regime invited filmmakers from countries then considered friendly (read: Communist), including People's Republic of Poland, which sent a team under Andrzej Fidyk. The documentary is primarily composed of declarative statements, as well as texts of North Korean newspapers and books. There was no author's commentary. Fidyk commented that he and his team were likely “the most disciplined” foreign team of filmmakers in North Korea, as they did not trouble the regime by looking under the surface - they were content with what they were given and asked to do.
