Once World War II began, light cheerful escapist films were much in demand, and von Borsody was cinematographer for the romantic musical drama Wunschkonzert ("Request Concert"), one of the most successful films of the entire Nazi period. Ilse Werner plays a young Berliner, who patiently and trustingly awaits the return of the man to whom she is engaged, played by Carl Raddatz, ordered on a secret mission to Spain. The film was classified as "politically valuable", "artistically valuable", "valuable for the people", and "valuable for youth", and took 7.6 million Reichsmarks.
