'De ordening'is Dutch for 'the ordination'.
Based on the book with the same title by Kees van Beijnum (1998).
The commemoration at the grave of De Heus Verolmen was filmed at the Roman Catholic Cemetery Sint Petrus' Banden in The Hague. Meinoud Marinus Rost van Tonningen, who served as a model for De Heus, was buried after his suicide at the Municipal Cemetery in The Hague, close by. His grave was cleared after ten years.
The film is partly based on the life story of the widow Rost van Tonningen. She was not involved in the realization of the film. Meinoud Rost van Tonningenh collaborated extensively with the occupation forces during the German occupation of the Netherlands in World War II. After he was taken prisoner by Canadian troops he commited suicide. His second wife, Florentine Rost van Tonningen, continued to promote pro-German and National Socialist views, denying the Holocaust and regretting the fall of the Third Reich and any threat to racial purity.
