Tarzan's Greatest Adventure is a 1959 adventure film directed by John Guillermin, produced by Sy Weintraub and Harvey Hayutin, and written by Les Crutchfield, based on the character created by Edgar Rice Burroughs. With a strong supporting cast that included Anthony Quayle and Sean Connery, and a focus on action and suspense, the movie won critical praise as a Tarzan film that appealed to adults as well as children.
The film features a literate Tarzan portrayed by Gordon Scott. The character of Jane, Tarzan's wife, does not appear and is not mentioned. At one point, Tarzan briefly romances a female character, suggesting that he is a loner, not a family man. Cheeta, Tarzan's chimp companion in many movies, appears only a few times near the start of the film, and the kind of comic relief that Cheeta represents is generally absent from the movie.
