The live-action adaptation of the Hank Ketcham comic strip of the same name. Dennis Mitchell was a loveable young boy, dressed in overalls and carrying a slingshot in his pocket. Everywhere he went, Dennis’ wide-eyed curiosity, well-meaning attempts to help out, and his simply being a normal, red-blooded American boy growing up always seemed to lead to trouble. Usually on the receiving end was Dennis’ next-door neighbor, retired business machine salesman George Wilson. Dennis worshiped Mr. Wilson, but he usually displayed a less-than-cordial attitude around the young lad. Mr. Wilson’s wife, Martha, adored Dennis and saw him as a surrogate grandson (since the Wilsons never had any children).
