The Wall (1962 film)

The Wall is a 1962 American propaganda film directed by Walter de Hoog about the erection of the Berlin Wall.

Since the 1960s, the short documentary was preserved by the U.S. National Archives and Records Administration. Since the film was deemed a propaganda film, the media production could not be released or shown in the United States until after the Cold War between the Eastern Bloc and Western Bloc countries.
