Here, she plays a woman who leaves her husband (Robert Young) for his presumed infidelity, and proceeds headlong toward a rapid rebound marriage to some rich guy (Robert Hutton) after a hasty Reno divorce. When she finds herself fainting on the way to the altar, attributed soon thereafter to pregnancy by her ex, custody complications ensue and provide fodder for "who's going to be the father next year."
All parts are well-played, but Young shines here in a sympathetic role, wanting nothing more than to re-assume his rightful place as husband (and father). "Other man" Hutton is fine, too, but his signature role for me will always be that of Cpl. Ed 'Slim' Green, the star-struck soldier in "Hollywood Canteen". The "other woman", to round things out, is played by Janis Carter (not to be confused with Janis Paige, who also appeared in "Canteen").
Lou Breslow's script offers sufficient twists and turns in romantic connections to justify the comedic wonderment, including a play on the title later in the proceedings, and one in the closing dialog if one is alert enough to catch it.
