Aren't We All? (1932)

Because his father, Lord Grenham, spends more time philandering with attractive women than conducting business, Willie Tatham is forced to interrupt his honeymoon with his wife Margot in the south of France and return to London to get his father to sign an important contract. While Margot, an actress, goes to a small resort where she will not be recognized, Kitty Lake, one of the young women Lord Grenham pursues, flirts with Willie. Two weeks pass and when Willie tells Margot on the telephone that he must stay in town, she threatens to engage in a violent flirtation with the next attractive man she sees. Karl von der Heide, from Vienna, who is waiting to use the telephone, overhears her and begins a flirtation. She identifies herself to him as Mrs. Margaret Spaulding, and they pursue the beginnings of a romance until Margot suddenly returns home.
