An underrated gem from 1970 is director Martin Ritt's "The Molly Maguires" which told the story of oppressed Irish coal miners in Pennsylvania and how they launched a violent resistance campaign in the quest for gaining livable wages and working conditions. The film was a major flop despite the presence of stars Sean Connery and Richard Harris but time has been kind to Ritt's thoughtful and engrossing film and its moral issues still resonate today.
