The film version of the best selling novel The Egg and I with Fred MacMurray and Claudette Colbert introduced America to the Kettle family. Marjorie Main and Percy Kilbride and their brood of 15. They were the rural answer to Clifton Webb and Gene Tierney's Cheaper by the Dozen. Who says country folk can't do it better.
In this film we have the arrival of the Kettles first grandchild who Percy mistakes as another blessed event of his own creation. A natural mistake given his track record. The baby however is Meg Randall's who married their oldest son Richard Long in a previous film. The Kettles also have to contend with Meg's parents, Ray Collins and Barbara Brown. Ms. Brown is one snooty old dowager, but I think you can gather that if anyone could adjust her attitude, Marjorie Main could.
Due to a pair of radioactive overalls, the Kettles also think they've got uranium on the old homestead. So do a pair of crooks who try to steal the place from them.
The Kettles were a really popular item in what would now be called red state America back in the day. The pictures made money consistently for Universal and if Percy Kilbride hadn't decided to retire, I'm sure more would have been made. There was one more made with Arthur Hunnicutt as an in-law, but it wasn't the same without Mr. Kilbride. Marjorie Main retired not long after that last film also.
If you are any kind of fan of those CBS rural shows of the sixties like Beverly Hillbillies, Petticoat Junction, and Green Acres, the Kettles are your cup of tea.
