Jahrmarkt der Liebe

Dana Andrews's singing voice was dubbed by radio singer and announcer Ben Gage, who at one time was married to Esther Williams. The studio was unaware that Andrews was a trained singer. He later explained that he didn't correct the oversight because he figured the ghost singer also needed to earn a living and he didn't want to deny his colleague employment. Ironically, despite his training, in a film career that lasted three decades, Andrews never displayed his singing voice on screen.

Several of the trees seen on the Frakes' property early in the film are recognizably eucalyptus trees, with their sparse leaves and white trunks. Eucalyptus trees grow easily in California and in similar climates (e.g., around the Mediterranean or in Australia), but would not survive the harsh winters in Iowa.

There is an Italian edition of this film on DVD: " LA BISBETICA INNAMORATA (1938) + FESTA D'AMORE (1945)", distributed by DNA Srl (2 Films on a single DVD), re-edited with the contribution of film historian Riccardo Cusin. This version is also available for streaming on some platforms.
