Natalie Kingston and Mildred Washington's last movie.
Final film of actresses Lucille Powers.
The World War I footage in this film was taken from Lewis Milestone's 1930 film All Quiet on the Western Front.
According to the on-screen credit, the film's story line was "suggested" by the 1931 nonfiction bestseller Only Yesterday by Frederick Lewis Allen, who had sold Universal the rights to his book. The film is set in a time frame close to that of Allen's book but otherwise bears no resemblance to it, and the film's title may simply have been an attempt to capitalize on the book's fame at the time of the film's release. The plot of the film appears to be based closely on Letter from an Unknown Woman (Briefe einer Unbekannten) by Stefan Zweig, published first in 1922 and in English translation a decade later.
