If you're pro-union, you should watch Harlan County USA. If you've ever been slightly agitated at your boss, you should watch Harlan County USA. If you like bluegrass tunes crooned by old ladies, you should watch Harlan County USA. Let's say you don't fit into any of those categories—you should still watch Harlan County USA (and maybe develop a little class consciousness while you're at it). Barbara Kopple's legendary '76 documentary, which won the Oscar for Best Documentary and has since ranked on Sight & Sound's critics' poll of the greatest films of all time, will screen at Clinton Street Theater for free this week in support of the New Seasons Labor Union. It follows a grueling coal miners’ strike, complete with murderous bigwigs, shitty cops, and no-nonsense wives that keep guns in their bras. You will despise capitalism even more once you're done watching it. Enjoy.
