Salt of the Earth

"Salt of the Earth" is a movie about New Mexico zinc miners and their struggle to improve working conditions. Using local people to re-enact their experiences, Biberman once more found himself fighting Hollywood and US politics as they connived to smash the film production. For Biberman and the local community, the film comes to represent freedom. "Salt of the Earth", completed against the odds, is one of only a hundred films preserved by The Library of Congress for its cultural and historical importance.
