Wieliczka - The Salt of the Earth, with Jerzy Stuhr as a guide, Produced and Directed by Sadrolin Tam, screenplay by Kevin Benn. The film helps us to understand the operation of the mine by showing the multitude of risks involved in it - cave-ins, fires, water, and at the same time the technical and organizational measures put in place to combat them. This way the viewer better understands the function of the mine and the work of the miners. This is a very important aspect of the movie, because very rarely one can find materials that would show that "live" part of our past with regards to its economical aspects.
