"I Was Faithful" was the film's working title and ironically became its reissue title in the 40s.

Film debut for Viva Tattersall, who plays Millie.

Talkie debut for Phyllis Barry, who plays Doris.

The second of two films starring Ronald Colman and Kay Francis.

The title comes from the 1894 poem "Non sum qualis eram bonae sub regno Cynarae" (a quotation from Book IV of Horace's Odes) by Ernest Dowson (1867-1900) in which the narrator tells his former lover, Cynara, of his attempts to forget her. The poem's refrain "I have been faithful to thee Cynara! in my fashion." is shown as frontispiece to the film.

The Dowson poem from which the film gets its name contains the line "I have forgot much, Cynara! gone with the wind.", which gave Margaret Mitchell the title for her novel (although a title-card by Ben Hecht in the movie attributes it otherwise).
