Synopsis: Young Mason Gamble (who won the title role over 20,000 hopefuls) is all-boy, all-menace, all-Dennis, right down to his slingshot and dog Ruff. As long-suffering neighbor George Wilson, Walter Matthau is a marvel of lovable grumpiness. And Christopher Lloyd (Back To the Future) adds a new wrinkle to Dennis's neighborhood as a grungy lowlife who's no match for a certain 5-year-old. "Hey, Mr. Wilson!"-and everyone else: "Dennis the Menace is an irresistible treat" (Bill Diehl, ABC Radio Network).
