Powaqqatsi is the second of the feature-length "non narrative" films produced, directed and co-scripted by Godfrey Reggio. As in his earlier Koyaanisqatsi, Reggio utilizes a collage of sounds and gorgeous, manipulated images to make a comment on modern life. And as in the earlier film, Reggio's imagery is backed up by a haunting Philip Glass score. This time, Reggio concentrates on Third World cultures, and the way those cultures are perceived and sometimes exploited by the power merchants of the world.
