Almost 70 years ago, the then director of Frankfurt Zoo, Prof. Bernhard Grzimek (1909-1987), shot this famous animal documentary about the African continent with his son Michael. The documentary was considered an impressive plea for the preservation of Africa's animal paradises at the time. It vividly illustrates the far-reaching consequences of the impending loss of what were then still largely untouched natural landscapes. Despite visible signs of age, the film has retained much of its fascination as a contemporary document to this day.
