Pretty Woman is really just My Fair Lady, without the watchability. A better version of the story might be Fellini's Nights of Cabiria. There are doubtless many other variations on the same theme.
Pretty Woman is without Audrey Hepburn, too.
LabelKing . . . have you seen Suddenly, Last Summer? If not, then you MUST. It's unbelievable.
Another, EXCELLENT 'woman's picture,' is Room at the Top, with Simone Signoret, and Laurence Harvey. Ms. Signoret won a Best Actress, Oscar for her role as an aging actress who can't compete against a younger woman, who has money besides. It sounds corny, but it's not.
