Over the course of his career, filmmaker John Marshall shot more than one million feet of film and video (722 hours) of the Ju/'hoansi (!Kung Bushmen) of Namibia's Kalahari Desert. This body of work is unrivalled as a long-term visual study of a single group of people. Contained in Marshall's footage are the personal histories of individuals, documents of a now non-existent way of life, and the unfolding of massive social and economic change as experienced by one group of people over a period of fifty years. A frequent innovator in the field of ethnographic film, Marshall produced twenty-three films and videos and one multi-part series from his extensive footage archive. Marshall's approach to filmmaking evolved alongside changes in film and video technology, in the fields of anthropology and ethnographic and documentary film, and on a very personal level, in Marshall's relationship to the Ju/'hoansi. These shifts can be seen throughout the course of his career, as he moved from the almost scientific, observational style of First Film (his earliest footage), to the nuanced and self-reflexive epic, A Kalahari Family anthropology.
