Salt of the Earth (1954)

Salt of the Earth (1954) is a feminist independent labour relations HUAC-influenced overtly left wing civil rights and anti-capitalist voiceover ensemble drama movie, not so noir in flavour as in provenance, and yet a study in defiance, gender and class in the minerally and ethnically graped American wasteland. 

In the scorched, unforgiving landscapes of New Mexico, Herbert J. Biberman's Salt of the Earth rises like a monolith against the decrepit remains of an industrial empire. 

The Hollywood Ten (1950)

The Hollywood Ten (1950) is a documentary short from the heart of the film noir era dealing with the heart of the film noir issue as it deals HUAC-style with the predictive enforced persecution of American citizens in the form of ten Hollywood working men who were found in contempt of the House Un American Committee in the early hey day of American political persecution, indeed back in the days when it meant so much more, to so many more. 

This was not a social media event, but prefigures some of our crazed modern censoring in a few material manners.
