He authored another half-dozen films during the remaining years of the 1930s, before devoting his efforts full-time to this manuscript.
Harlem Cavalcade was an epic story of life among Black-Americans, beginning with their relationship to the Dutch community of New Amsterdam in 1626, through 1938.
A series of vignettes, it incorporated the real-life stories of such notable Americans as Booker T. Washington, Frederick Douglas, George Washington Carver, Joe Lewis, Satchel Paige, and Cab Calloway.
