Der lachende Mann/The Laughing Man – Bekenntnisse eines Mörders (GDR, 1966)
Interesting 1966 GDR documentary about ex-Wehrmacht/ex-US Army mercenary Siegfried "Kongo" Müller who, with a smile on his face and a swastika iron cross on his chest, tells of slaughtering countless people in the Congo on behalf of NATO and "Western values.". Müllers unit was responsible for some of the worst massacres of the 1964 Congo Crisis.
