Maureen O'Sullivan has left the jungle, but Brenda Joyce makes for a very fetching Jane. Johnny Sheffield matures before our eyes as Boy. And Weissmuller still manages to avoid loincloth malfunctions as he swings through the trees and tangles with animal and human adversaries. He is both a role model ("Never kill for fun, only for food," he tells Boy at one point) and something of a jungle chauvinist ("Jungle much more peaceful before woman come," he jokes with Jane). But the breakout star of these films is Cheetah, who effortlessly steals every scene he's in, whether covering his eyes when Tarzan and Jane kiss or parachuting out of an airplane. His finest moment comes at the end of Tarzan Triumphs, when his simian squeals broadcast over a shortwave radio are mistaken by German officers for the voice of "the Fuehrer" It's a Hollywood cliché, but truly, they don't make 'em like this anymore! --Donald Liebenson
