I'm watching the 2005 documentary THE DAY THAT PANICKED AMERICA (yet another one, but this time quite superior.) It states that after the Voodoo Macbeth, Welles "worked on" the 15-minute WPA film WE WORK AGAIN, about African Americans during the depression and the jobs available through the WPA. Included in the documentary are a few minutes from the film.
Does anyone know in what (if any) capacity Welles worked on this film? It doesn't look particularly Wellesian, and I don't recall hearing of it before.
