AllMovie

In Old Missouri is an entertaining Republic "regional" aimed at the thriving Country-Western fandom of the 1940s. Heading the cast are The Weaver Brothers and Elviry, a popular cornpone aggregation of the period. In a plot that predates The Beverly Hillbillies by two decades, the Weavers are bullied around by the snooty family of millionaire Pittman (Thurston Hall). But when the chips are down and the Pittmans face bankruptcy, it is Abner, Cicero and Elviry (Leon, Frank and June Weaver) who come to the rescue. Slickly produced despite its obviously skin-tight budget, In Old Missouri holds up surprisingly well when seen today; as a bonus, the nominal romantic lead is played by none other than Alan Ladd!
