"Stern, étudian Juif d'Amsterdam" - "Stern, a Jewish student from Amsterdam"
("the Jewish dimension" of Night and Fog, those few words... not necessarily a censorship issue but another one, more complex)

In 1956, the German government successfully pressured the French government into withdrawing Night and Fog from the Sélection Officielle at the Cannes Film Festival. The Swiss refused to show the film because of their "neutrality" (!).

Other victims of censorship include:
In the U.S.: Let there be light! by John Huston - about the psychological damage on U.S. soldiers returning from WWII,
In France: Les Statues Meurent Aussi/The Statues Die Also by Alain Resnais and Chris Marker - on colonialism and racism.

A book showing what is still today kept from the general public is War Against War by Ernst Friedrich.
