The most recent documentary film, The Silence of Innocence, offers first-hand footage and interviews. The title refers to a recurring theme in the history of art of Infanticide, as told in the book of Matthew and painted by Peter Paul Rubens (Flemish 1577-1640). A second documentary, Ninth November Night, shows the monumental outdoor exhibition staged by Helnwein in 1988, of 15-foot high painted portraits of downcast children hung on the 300 foot-long wall between the Cathedral of Cologne and the Museum Ludwig. The work poignantly demands remembrance of the crimes of Reichskristallnacht, or "Night of Broken Glass," November 9, 1938 when the Nazi regime first coordinated large-scale attacks on German and Austrian Jews and their property, presaging the destruction, deportations, and mass murder of the Holocaust.
