Paramount Pictures paid Glyn $50,000 for the concept, gave her a small part in the film as herself, and gave her a "story and adaptation" credit.

Hope Loring, Louis D. Lighton and George Marion Jr. (intertitles) wrote the screenplay and Carl Sandburg noted that Glyn's magazine story was "not at all like the film, not like it in any respect."
In the original version of the story, the character with the magnetic personality was a male.
Paramount producers suggested the character be female.
Also the original female character, Ava Cleveland, was upper class whereas Betty Lou is working class.
Nevertheless, Glyn was fully involved in the film adaptation and was very flexible about the transition.

This is one of the first examples of a "concept film", as well as one of the earlier examples of product placement.
The concept of "It" is referred to throughout the film, including the scene where Glyn appears as herself and defines "It" for Mr. Waltham.
Cosmopolitan magazine is featured prominently in a scene where the character Monty reads Glyn's story and introduces it to the audience.

Stage actress Dorothy Tree had her first film role in a small, uncredited part.
A young Gary Cooper was cast in a minor role as a newspaper reporter.
