For those interested in the supposedly disproportionate "popularity"
of movies in the South and its influence on Hollywood, see Thomas
Cripps, "The Myth of the Southern Box Office:  A Factor in Racial
Sterotyping in American Movies, 1920-1940," in _The Black Experience
in America_, ed., James C. Curtis and Louis Gould (Austin: UT Press,
1971).
 
The title says a great deal.  Also, its important to remember that
southerners were well represented, at least in the 30s, in the Hays
Office.
