Tarzan's Magic Fountain was Lex Barker's first turn as Tarzan, and Brenda Joyce's last as Jane (making her the only Jane ever to appear opposite two different Tarzans). Barker is a bland choice for Tarzan, especially in Johnny Weissmuller's shadow. At any rate, Tarzan's Magic Fountain is about yet another tribe of people hidden in the jungle somewhere. In their secret valley is a fountain of youth, which keeps a woman who crash-landed in the jungle decades ago young. But she must return to the outside world, and when word of the fountain leaks out, unscrupulous men try to find and exploit it.

This series entry is severely hampered by some ridiculous logic flaws. When the woman is seen first young, then twenty years older the next day, Jane figures it out and the badguys figure it out, but each acts as if the other should not expect anything out of the ordinary. Hello? The rest of the story is similarly forced. There are some interesting action scenes toward the end, but it's too little too late.

Elmo Lincoln, the original Tarzan from 1918's Tarzan of the Apes and a couple subsequent episodes, has a cameo as a fisherman.
