A mining catastrophe in the hands of an able director, G.W. Pabst. Story is based upon the disaster at Courrieres, on the German-French border, in which several hundred French miners were imprisoned underground and freed by their German colleagues.Pabst has made it a powerful recounting and accentuates more the happenings than the men. Breaking mine shafts, giant sheets of flame, the unflagging fight for escape. Panic seizes the whole town. Photography and architecture are excellent and the sound is clear. Picture sometimes abrupt and there are some superfluous scenes but this is an outstanding film.
