Judging by the number of times it's popped up on TV, Tarzan's Secret Treasure was one of the most popular of the MGM "Tarzan" pictures, though it's hardly the best. This time around, a group of gold hunters invade the domain of Tarzan (Johnny Weissmuller), Jane (Maureen O'Sullivan) and Boy (Johnny Sheffield). Expedition leader Professor Elliot (Reginald Owen) is an honorable man, but his assistants Medford (Tom Conway) and Vandemeer (Philip Dorn) are scoundrels, while the party's aggressively Irish general factotum O'Doul (Barry Fitzgerald) remains an enigma until the final reel. Thinking they've done away with Tarzan, Medford and Vandemeer force Jane and Boy to lead them through the jungle to a hidden gold mine, only to be captured by a hostile tribe which specializes in literally tearing its captives apart (via tastefully gruesome stock footage from 1936's Tarzan Escapes). Will ol' Tarz revive in time to rescue his loved ones from fierce tribesmen and even fiercer crocodiles? Perhaps the "campiest" of MGM's "Tarzan" entries, Tarzan's Secret Treasure is chock full of laughable vignettes, one or two of them intentional. Best line: When Jane asks Boy what he's been doing all day, the plucky youngster, who's just survived a series of hair-raising perils culminating with his nearly being burned at the stake by superstitious natives, replies "Oh, nothing much."
