The advance publicity booklet on the film when it was entitled "Africa Sings", touted it as showing "what the white man achieved for himself" and "what he has done for he natives." "Africa Sings" was one of the first documentary films from South Africa to take a look at the lives of South Africans of all races. There are images of location life, schools and colleges, and a cross-section of occupations, from mine-workers to road-gangs, school-teachers to house- servants, waiters to cane-cutters. Mainstream reviewers gave the documentary a tepid response; the London Daily Worker thought it was too bland to serve a staunch liberationist purpose.
To the North of the country, the Island of Ibo was used as the jail where the Portuguese political police tortured without remorse the Mozambique nationalists. This documentary reflects that jail, the consequences of colonization and the Resistance.
Couldn't Be Fairer reveals how Australia's first people are still suffering from social oppression, with many living on reservations where alcoholism is rampant and unemployment the major occupation. Aboriginal land rights are a central theme: Miller clearly demonstrates the contrast between the attitudes of European Australians, who see the land only as a resource to be mined, farmed, grazed and built upon, and Aboriginal Australians, who regard the land as sacred. Archival footage compares the original lifestyle of Aboriginal Australians to their current pitiful condition, and shows how European settlers attempted to "civilize" mixed blood children by taking them away from their parents and enrolling them in boarding schools.
