The Director of the Holocaust - Khazar Expatriate Billy Wilder
Almost all the films you've ever seen of the Holocaust were staged. Using Allied propaganda as a rough script, directors from Hollywood were shipped to Germany and Poland to direct propaganda films for post-war use. One of the most notable of these was Billy Wilder, director of meny very well known films, such as "Some Like It Hot" with Marilyn Monroe."
If you thumb through the photographs and film macabre film clips made by these directors, you will notice something odd. Among the living, many of the forlorn faces of the "death camp survivors" look oddly familiar. That is because some of the same actors were used in several shots, from totally different locations! The involvement of film crews also goes to explain why almost all of the "concentration camp" shots were dated at least 4-5 days after the camps were liberated. They were location shots, sometimes using prisoners (minus their usual camp clothing), and sometimes actors.
Real footage of the concentration camps was almost never used in the Allied propaganda films. But, you can find some of this real footage on Internet Archive.
In the 1970's, the stories passed down about the WW-2 German prison camps were welded together into a narrative we now call "the Holocaust" - meaning "the burnt offering." Through telling and re-telling, the Holocaust has grown to a multi-million dollar industry, and has changed to mean something particular to Jewish history. It has been used to found a nation (Israel), and to justify many exceptions to morality.
