'Unsung Hollywood' goes beyond 'Foxy Brown' in telling the story of Pam Grier

First she was Coffy. "The baddest one-chick hit squad that ever hit town." Then she was Foxy Brown. "A chick with drive, who don't take no jive." Pam Grier was not just the most prominent female action star of blaxploitation movies of the 1970s, but also the first big box-office female action draw in all of film.
