The Lost Tribe was the 2nd entry in Columbia's "Jungle Jim" series. Johnny Weissmuller stars as Jungle Jim, the comic-strip adventurer created by Alex Raymond way back in 1934. The plot is motivated by a lost treasure, located somewhere in the faraway land of Dzamm. Villains Calhoun (Joseph Vitale) and Rawling (Ralph Dunn) scheme to steal the treasure, but Jungle Jim won't let that happen. Our hero summons forth an army of gorillas to fight off the bad guys. Many of the animal-fight sequences in The Lost Tribe would pop up as stock footage in future "Jungle Jim" entries. The film is graced with the presence of two exotic leading ladies, Myrna Dell and Elena Verdugo.
