Ex-Lady (1933)

Synopsis
In this romantic sex-comedy from director Robert Florey, Bette Davis stars as Helen Bauer, a free-spirited, self-sufficient feminist who would rather pursue her career as a graphic artist than settle down and marry Don Peterson (Gene Raymond), the advertising writer she loves, out of fear that marriage will destroy the romance. Eventually, Don wears Helen down and the couple marry. But when the flame quickly burns out, Don begins an affair with a female client. Not to be outdone and without missing a beat, Helen takes up with Nick Malvyn (Monroe Owsley), another ad writer, who by no coincidence also happens to be Don's biggest rival. In light of their respective bouts of infidelity, the couple must consider whether or not they want to give the marriage another shot. ~ Matthew Tobey, All Movie Guide
