Marilyn Monroe was Twentieth Century Fox's original choice for the role of Evelyn Nesbit. She turned down this movie, as well as a planned remake of Wabash Avenue (1950) titled "The Girl in Pink Tights" (which was to co-star Dan Dailey and Mitzi Gaynor). As a result, she was put on suspension. The studio also ordered screen tests for Terry Moore and Debra Paget. Sheree North was then announced as her replacement for both movies until Dame Joan Collins was eventually cast as Nesbit. "The Girl in Pink Tights" project was eventually abandoned.

Aired for the first time on Turner Classic Movies on Tuesday, September 20, 2022.
