Well.....Constance Bennett through Ms Sue Mengers drove a hard bargain with producer Ross Hunter who wanted her badly for the role of the Mother in MADAME X. Bennett was married to an Air Force Brigadier General and hadn't made a film in a few years, preferring to play poker and be a society matron.
One thing she continued to demand was that her name be in a box on all advertising. Negotiations continued while Bennett flew off to Switzerland to get some plastic surgery - she had been deathly afraid of doing it before, but felt a return to the big screen demanded it.
Billing was set at her being 4th billed after the title, and special "Constance Bennett as Estelle" on screen (Keir Dullea also received the same billing ",,,,,as Clay, Jr."
The plastic surgery had some complications and Constance Bennett died before the film was released (critics wrote that when John Forsythe greeted her as "Mother" in her first scene, there were gasps in the audience at her visage).
At her funeral, Sue Mengers was among those in attendance. As the service began, she was heard to remark: "Well, Connie finally got her box."
