Of Deanna Durbin's 21 features released between 1936 and 1948, only this film opened at Manhattan's famed Radio City Music Hall, starting October 2, 1941.
The star-making five-year association of Deanna Durbin, producer Joe Pasternak and director Henry Koster ended following this film. After Mr. Pasternak moved from Universal to MGM, Miss Durbin went on suspension between October 16, 1941 and early February 1942 for refusing to appear in "They Lived Alone," planned to be directed by Mr. Koster. Ultimately, the project was canceled when Deanna and Universal settled their differences. In the agreement, Universal conceded to Deanna the approval of her directors, stories and songs.
