This third entry in Universal's money-spinning "Ma and Pa Kettle" series once more stars Marjorie Main and Percy Kilbride as the title characters. This time, the Kettles extend their hospitality to their stuffy Boston in-laws (Ray Collins and Barbara Brown). Trouble brews when the Bostonites offer to raise the Kettles' grandson in a more "suitable" environment--namely, their own. The plot goes off on another tangent when it is presumed that the Kettle farm is rich with uranium. Ma and Pa Kettle Back on the Farm delivers the goods for fans of the series, and even provides a few bright and funny moments for non-fans. ~ Hal Erickson, Rovi
