C.S.A.: The Confederate States of America (2004)

Set in an contemporary alternative world where the Confederate States of America managed to win the American Civil War, a British film documentary examines the history of this nation. Beginning with its conquest of the northern states, the film covers the history of this country where racial enslavement became triumphant and the nation carried sinister designs of conquest. Interspersed throughout are various TV commercials of products of a virulent racist nature, as well as public-service announcements that promote this tyranny. Only at the end is it revealed that the film contains less wholly-imagined material that the viewer might suspect.
