Although the origin of the screenplay is not credited, the Motion Picture Herald stated that the film was based on a story written by Melville Crossman (a pseudonym of Darryl F. Zanuck), which appeared in Liberty Magazine. However, no other source mentions that story.

This film was made and released before Barbara Stanwyck and Robert Taylor were married. In the oversized, 22-page press book that the studio had prepared for the exhibitors, there were constant references to and blurb lines describing Stanwyck and Taylor as "real-life sweethearts" or "real-life heart interests", etc., stills captions particularly, typical 1930s selling points to be used in the advertising. However, somewhere between the planning and the execution, something went amiss, and the pressbook had an 8x10 snipe pasted on page three with specific instructions: Dated May 26, 1937, and addressed to Exhibitors as IMPORTANT NOTICE. It read: "Delete the phrase "real-life sweethearts" and any similar phase, or any stunts or copy along the same line from all advertising or publicity on THIS IS MY AFFAIR. In utilizing any of the press book materials you will please correct the copy, eliminating the words "real-life sweethearts." Please note that this applies to everything in the press book, publicity copy, ads, exploitation, stunts, etc. Your cooperation will be appreciated." (signed) Charles E. McCarthy-Advertising Manager
