Joan Crawford was originally set to act as onscreen "hostess" for the film's coming-attractions trailer, but this was scrapped when Fox refused to accede to Crawford's request that the trailer also feature a prominently displayed Pepsi-Cola bottle.
In early 1959, Jean Peters was set to make her comeback in this film. It would've been her fifth film under direction of Jean Negulesco.
In the first scene of the film, Caroline (Hope Lange) is reading a "Help Wanted - Female" ad in the paper which shows the real-life address of the building in front of which she is standing and later goes to work. This is the famous Seagram Building in NYC at 375 Park Avenue.
Inspired a short-lived daytime TV soap opera of same name that premiered in 1970.
The original score, created by esteemed Hollywood composer Alfred Newman for Twentieth Century-Fox, was the last in an association dating back to The Bowery, two years before 20th Century Pictures amalgamated with Fox. Only one more assignment brought back Mr. Newman to his former home studio: as musical director (with assistant Ken Darby of a mild filming of Rodgers and Hammerstein's State Fair. Worth noting, Mr. Newman (and associate Charles Henderson)) had netted an Oscar nomination for serving in the same capacity on the appealing 1945 version.
This film features many important Manhattan sites. Thirty-three minutes into the film, Caroline Bender (Hope Lange) and April Morison (Diane Baker) are crossing Christopher Street from south to north near where Waverly Place comes into Christopher Street east of Sheridan Square. They walk east on Christopher Street, while carrying on a conversation. Look above their heads. In the rear, you will see the red neon sign of The Stonewall Inn lit up, even though the afternoon sun is still shining. Yes, this is the same Stonewall Inn where a decade later the modern gay liberation movement began when drag queens confronted police who had come to raid the bar.
This was the first time Joan Crawford accepted a supporting role in a movie, supposedly because she found herself in debt after the death of husband Alfred Steele early in 1959. According to cast member Diane Baker, Crawford's role was cut even further before release, causing the removal of a show-stopping drunk scene by Crawford. Bits of this scene are in the trailer included on the DVD.
