Sweet Sweetback's Baadasssss Song (1971)

Synopsis
Produced, directed, written, scored by, and starring Melvin Van Peebles, this landmark "blaxploitation" film was as controversial as it was popular for its then X-rated story of one African-American man's triumph over the Man. After beating a couple of white cops he witnessed brutalizing a local black revolutionary, sex show performer Sweetback (Van Peebles) has to go on the run. As he flees through decrepit South Central Los Angeles, Sweetback demonstrates his formidable potency through sex as well as violence, evading the police manhunt by any means necessary. As Sweetback runs off into the sunset, however, Van Peebles warns that the story, like the 1960s racial strife, isn't over. ~ Lucia Bozzola, All Movie Guide
