Madame Simone (Jacqueline Bisset) of Paris gives a visiting American journalist Joanna Scot (Linda Hamilton) some advice on reclaiming her marriage which is on the rocks. Madama Simone who runs a high-class whorehouse has had a lot of experience with men and women and the process of falling in love. Her home-spun philosophy is that if you feel good about yourself , then others will feel good about you too. Her recipe for success in romance seems to me rather too glib and her easy success leaves no surprises and the outcome is predictable. This is the fault of the script not the actors. The actors however do have their short-comings. I found Madame Simone's strong French accent clouded her diction at times and the journalist was supposed to be wondrously transformed with a new hair-do and gorgeous gown. For me it was not a remarkable change in her appearance, but yes, her outlook on life had changed. The odd photographer who breaks into the story is quick to notice a new face(and body) at party time. The photographer makes Mrs X feel important and provides the sex mentioned in the title. Based on a true life story, the film is largely a succession of events and conversations in a woman's life, and would perhaps have greatest appeal to women audiences. If you are a man leave Mrs.X to her own problems, and don't be misled by a catchy title.
