We're Not Married (1952)

Five married couples discover, to their shock, that they're not really married! The justice of the peace who presided over their nuptials didn't have a valid license. When they learn the news five years later, each couple must decide if they will remarry. Radio hosts Steve (Fred Allen) and Ramona (Ginger Rogers) couldn't harbor more animosity toward each other; but does that mean they should go their separate ways? Annabel, recently crowned Mrs. Mississippi, has more of a semantic problem.
