But before I jump into the performers in these films, let me discuss the foundation of these films. Race films were produced as early as 1905 but flourished after 1915. Over 500 movies were made between 1915 and 1952. The main White-owned companies were Million Dollar Productions and Toddy Pictures. The few Black-owned outfits were Lincoln Motion Picture Company and Chicago-based, Micheaux Film Corporation. Micheuax proudly advertised that his films were srcipted and produced by African-Americans.
Of course, these films were segregated when released in the South. They weren't welcome up North all that much either. Northern movie theaters showed them in Black neighborhoods too like the South did, but relented a litttle if shown elsewhere. Meaning? Black were seated in the "peanut gallery" of the theater (the balcony) or relegated to evening showings period. So much for Northern liberty! Whites were not interested in viewing these films. Yeah, right. I'll play along. It was partly true but look, what was a White chick supposed to do if she and her date (Mr. Brad) were watching a "Race film" and Mr. Brad were to get all hot and bothered by the negresse on the screen? Quel scandale! Can't have that. Why do you think any musical with a musical number showing a sultry Lena Horne or Dorothy Dandridge was CUT out of the film BEFORE it was viewed down yonder? Couldn't have those men folk all heated up by a...colored gal!
But I digress.
Many Black singers, dancers and performers that did go on to appear in "mainstream" Hollywood films made their mark in "race films" first.
