Tarzan's Magic Fountain (1949)

When an aviatrix (Evelyn Ankers) emerges from the jungle after being lost for 20 years, she still looks the same as if time hadn't passed due to a secret water source hidden deep in the jungle that restores youth. Two devious con men (Albert Dekker, Charles Drake) plot to discover the source and make themselves rich. But not if Tarzan (Lex Barker) has anything to say about it. The debut of Barker as Tarzan, taking over from Johnny Weismuller. The film itself is a rather silly concoction of jungle adventure and science fiction that passes the time amiably. If a little too much time is expended on the tiresome antics of Cheetah the chimp, Barker makes for a pleasantly easy going Tarzan and Brenda Joyce returning as Jane for the fifth and final time plays a more important part in the storyline than usual. Directed by Lee Sholem. With Alan Napier and Henry Brandon.
