I think that you may be looking for two documentaries by Riggs which deal with African-American media images: Color Adjustment (deals primarily with television) and Ethnic Notions, which traces the evolution of deeply rooted stereotypes (Toms, carefree Sambos, faithful Mammies, grinning Coons, wide-eyed Pickaninnies, ad nauseam). Both were distributed by California Newsreel as of 1993. California Newsreel 149 Ninth Street Suite 420 San Francisco, CA 94103
