Supporting actor Karel Stepanek emigrated during the nearly three years of production and was replaced by Rudolf Carl. Cutting and new shooting came to 500,000 RM additional production cost, because color processing had been developed further.
First German color film.
The film took nearly three years to complete because the Agfacolor film was not yet perfected and numerous takes were ruined and had to be re-shot over and over as better film stock was developed through trial and error during production.
Final film of Alexandra Nalder.
