Tarzan's Magic Fountain is a 1949 Tarzan film starring Lex Barker as Tarzan and Brenda Joyce as his companion Jane. The film also features Albert Dekker and Evelyn Ankers, was co-written by Curt Siodmak, and directed by Lee Sholem.
This was Barker's first appearance as Edgar Rice Burroughs' ape-man, while Joyce had played Jane opposite Johnny Weismuller as Tarzan in four previous films. She was one of only two actresses to portray Jane in movies with two different actors as Tarzan. (The other was Karla Schramm in the silent era.) Tarzan's Magic Fountain was Joyce's final turn in the role, and different actresses played Jane in each of Barker's four subsequent Tarzan movies: (Vanessa Brown, Virginia Huston, Dorothy Hart, and Joyce MacKenzie). Elmo Lincoln, who had been the first screen Tarzan three decades earlier, appears uncredited as a fisherman repairing his nets.
