Carl Theodor Dreyer - Vandet på landet AKA Water from the land (1946)

Quote:
Sharply critical film about rural water pollution in the Jutland countryside district of medical officer Jens Jensen. Situations of everyday water use are illustrated by graphic representations of a well and surrounding soil layers. A new well is correctly constructed in the farmyard.

The Farming Organisations, but above all the National Board of Health, killed the film because of its critical (read: realistic) depiction of water-well conditions in the country.
