This was filmed by an American film crew in 1957 in Mamelodi near Pretoria, South Africa. Mr. Prinsloo is a representative from the Native Affairs or Bantu Affairs department under Hendrik Verwoerd who was the minister of native affairs at that time looking after the interest of Black Africans. Note that there is no police or body guards present when Prinsloo is interviewed and he's questioned about the policy of separate development (and how the camera crew actually tries to cover this up by changing the perspective). The township has only recently been build for Blacks that previously were residing in south african slums.
