The title couple and their enormous brood of bumpkins made their movie debut in the film version of Betty McDonald's humorous book
The Egg and I (1947) where they appeared as supporting characters. Audiences found them funny and so the characters got their own long-running series of B movies. Ma and Pa Kettle is the first in that series and centers on the exploits of the impoverished hayseed family after Pa wins a contest by writing a jim-dandy slogan for a tobacco company. The Kettle's prize is a brand new, ultra modern, fully automated home. It's a good thing too, for Ma, Pa and their 15 kids were about to get booted out of their previous wreck of a home. Of course the film is at its funniest when the Kettles are trying to figure out how to operate their fancy new digs. ~ Sandra Brennan, All Movie Guide
