In my books, the best mining films were "The Molly Maguires" with Sean Connery and "Germinal" with Gerard Depardieu.
Almost mining: "The Wages of Fear", one of the most thrilling films I've ever seen - transporting truckloads of nitroglycerine to blow out an oil well fire is not for the faint-hearted 🙂 BTW: that's another movie where the remake was absolute crap.
