The mighty Lord of the Apes (Gordon Scott) is on a deadly trail. He's determined to find the diamond hunters (including Anthony Quayle and Sean Connery) who brought terror and death to a peaceful village. But as much as Tarzan is a tracker and avenger, he's also a protector. An irresponsible gadfly from the so-called civilized world intrudes on his quest and Tarzan knows he cannot leave her to fend for herself.

TARZAN'S GREATEST ADVENTURE stars Gordon Scott in his fourth screen appearance as Edgar Rice Burrough's lord of the jungle. Jane is absent from the proceedings, Cheetah the chimp is reduced to a bit part, and Tarzan himself is given a sophisticated vocabulary (in keeping with the Burroughs original). The storyline concerns a murderous diamond hunter (Anthony Quayle), an old enemy of Tarzan's who threatens to despoil the Ape Man's jungle domain. Among the villain's entourage is a young Sean Connery, playing a nasty chap who meets a nastier demise. While perhaps not as great as the title proclaims, TARZAN'S GREATEST ADVENTURE is one of the most consistently exciting entries in the Tarzan series, and worth a second glance today due to its top-drawer supporting cast.
