Answer
Wim Wenders was inspired to make'The Salt of the Earth' by the work of photographer Sebastião Salgado. Salgado's work focused on the lives of poor people in developing countries, and Wenders was struck by the beauty and humanity of Salgado's photographs. Wenders wanted to make a film that would show the world the beauty of Salgado's work, and to raise awareness of the plight of the poor.
