The film was the first successful sound film produced by the German major studioUniversum Film AG (Ufa) and was credited with establishing the popularity of the operetta film. It was shot in Hungary. Initially the film was intended to be silent, but halfway through production its producer Erich Pommer was ordered by his superiors to convert it into a sound film.[1]
Ufa had recently made a deal with the Klangfilm syndicate (consisting of Siemens & Halske, AEG, and Polyphon-Werke AG (who sold Polydor records) to license the Tri-Ergon sound film system, under the name 'Ufa-Klang'.[2][3] A previous attempt in 1925 by Ufa to use an earlier version of the same system, at the time owned by Klangfilm's former competitor, Tobis, had ended in failure.[4][5]
