The Valley of Love(1935)

Rather coarse, pre-War comedy about a Markgraf -- Heinrich XXVI -- who bathes in the springs of the Ammendorf to strengthen his potency. The town and its springs are especially well known for the many couples with lots of children, who, for tax reasons, live there unmarried. The town smithy and bully provides his vitality to ensure the countess has an heir for the throne.
