Popular Sin (1926)

Synopsis
According to this frothy comedy, the "popular sin" is infidelity, especially in Paris. Philandering husband George Montfort (Philip Strange) purchases railroad tickets for a weekend tryst in the mountains with his latest paramour. When his wife Yvonne (Florence Vidor) finds the tickets, George hastily explains that they were bought as an anniversary present for her. Yvonne doesn't believe George, but she decides to use her ticket anyway, while George remains behind in Paris on "business." During her weekend visit to a French resort, Yvonne meets and falls in love with handsome novelist Jean Corot (Clive Brook). Out of loyalty to her husband, she refuses to consummate her romance with Jean, but George arrives unexpectedly, assumes the worst, and files for divorce. On the rebound, Yvonne marries Jean, only to suffer the pangs of jealousy whenever her new husband is approached by one of his adoring female fans. Eventually, she catches Jean in what seems to be a romantic rendezvous with gorgeous actress Le Belle Toulaise (Greta Nissen). Another divorce follows immediately, whereupon Jean marries La Belle, who turns out to have dozens of lovers -- including Yvonne's first ex-husband George. Upon confronting George, Jean cannot help but like the man, and the two engage in a lively conversation, prompting La Belle to walk out on both of them! Another round of divorces ensues, resulting at long last in a tender reunion between Yvonne and Jean. ~ Hal Erickson, All Movie Guide
