Synopsis
Tarzan is a series that aired on NBC from 1966 – 1968. The series portrayed Tarzan as a well-educated character, one who, tired of civilization, had returned to the jungle where he had been raised. The show retained many of the trappings of the classic movie series, including Cheeta, while excluding other elements, such as Jane, as part of the "new look" for the fabled apeman that producer Sy Weintraub had introduced in previous motion pictures starring Gordon Scott, Jock Mahoney, and Mike Henry. CBS aired repeat episodes the program during the summer of 1969.
