Research documentary by Danish filmmaker Mads Brugger, Cold Case Hammarskjld
An amazing story of trying to find out how the UN General secretary Dag Hammarskjöld (Swedish) was killed in a plane crash in 1961 in Africa. It leads to findings about an operation in South Africa called South African Institute for Maritime Research run by a man with connections to Britain's M16 who worked to sow problems in Africa to keep whites in power. I found it to be totally credible, though it seems many movie critics have not taken it seriously. The US, Britain, South Africa and Sweden to this day have not released any information on this subject.
The director, Brugger, uses a technique of having 2 African secretaries who type out his dictation, which he did he said, to add flavor to the movie, but they seem out of place, like props.
