Love, Honor and Behave (1938) Wayne Morris, Priscilla Lane, John Litel

A woman raises her son Ted to be a good loser, in effect creating a weakling who never asserts himself. Even after marrying his childhood sweetheart Barbara and assuming family obligations, Ted cannot bring himself to fight for respect. The worm finally turns when Barbara starts stepping out on her Milquetoast husband, who then turns out not to be so passive after all. All comes full circle in this slyly symmetrical romantic comedy, with the final scene neatly skewering the complications set up in the opening reel.
