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.~ Hal Erickson, All Movie Guide
