The fans of Rita Falk's Franz Eberhofer book serial were incensed when one of the favorite characters, Ludwig, wasn't cast in this film. The next film, Winterkartoffelknödel, included Ludwig, played by Joker, a Picardy Shephard dog.
Höpfls curious neighbor couple are played by actors Gerd Lohmeyer and Monika Manz, who are actually married.
