The use of negroes in the background of movie scenes was stipulated, among other details, by the CIA division called the Psychological Strategy Board to one of their moles in Hollywood, Luigi Luraschi, who worked at Paramount Studios.
Lurashi, a long-time Paramount insider, was able to affect casting, scripts, choice of director, etc. Very nuts and bolts details.
Letters from Luschari back to the PSB from 1953 were declassified, perhaps by accident, in 1995 and written up in a 2000 issue of the Historical Journal of Film, Radio and Television by David N. Eldridge of the University of Hull, UK.
Eldridge makes statements about this CIA influence being perhaps temporary that don't stand up to what I've found from research which suggests that this micro-managing of film grew exponentially as domestic need dictated (Bay of Pigs, Missiles of October, Vietnam) until the product now coming out of Hollywood is almost all psy-ops from psy-ops factories and fronts.
Read for yourself the reports from one compartmentalized CIA asset in 1953 Hollywood who doesn't know the other CIA assets in Hollywood doing exactly what he is-
