Imperialism of not so long ago
It's interesting that at the beginning of the film the producers thank various governmental officials. The names of the governments are very telling, and they remind us that Imperialism flourished well into the 20th Century:
The Territory of Tanganyika
The Protectorate of Uganda
The Colony of Kenya
The Anglo-Egyptian Sudan
The Belgian Congo
They also thank four "White Hunters". How times have changed.
