Reception
In a contemporary review for The New York Times, critic Mordaunt Hall called the film's title "meaningless and unsuitable" and wrote: "This story, one of half-truths and fiction, ... is a conventional narrative and although Mr. Franklin delivers some imaginatively conceived sequences, there are others that are emphatically old fashioned in design. ... It is too mindful of the old things in motion pictures."[1]
Remake
The film was remade as the 1932 American French-language film titled Jenny Lind.
