Rübezahl's Wedding(1916)

In this film, the people of a Tyrolean town climb up into the nearby mountains, searching for a place where they can hold a picnic and a spring festival: ideally, a place where they can eventually erect dwellings and cultivate crops. Led by the local nobleman (Arthur Ehrens), they find an appropriate spot, and the festivities begin. Some children briefly perform a charming folk dance. Suddenly the Rübezahl arrives and threatens to kill all the townsfolk if they don't leave immediately.
