Harlan County USA trailer, 1976
Gripping, bittersweet, Oscar-winning documentary following the herculean efforts of coal miners in Kentucky as they attempt to unionize. Criterion Collection, and available to watch instantly on both Hulu and Netflix.
Even if you’re not interested in the union/corporate/political aspect (which you should be), you’ll love it for the cinematography, excellent bluegrass soundtrack, and foggy 70s aesthetic.
