The Devil and Miss Jones is a social comedy with left-wing undertones. John P. Merrick (Charles Coburn), the world's richest man, gets word that someone is trying to unionize a department store that he owns. To thwart this blatant act of democracy, Merrick changes his name and takes a menial job at the store, the better to catch the union activists without detection. Once he himself is subjected to the humiliating treatment afforded his employees, Merrick starts to wise up -- and soften up. As things develop, it is Merrick himself who spearheads the union movement after discovering how duplicitous his hand-picked executives can be. The film also introduces Jean Arthur and Robert Cummings as fellow employees who fall in love before fadeout time. Keeping with the film's insistence upon equal treatment for everyone, Merrick himself is permitted a romance in the person of Elizabeth Ellis (Spring Byington). The Devil and Miss Jones was written by Norman Krasna and directed by Sam Wood.~ Hal Erickson, All Movie Guide
