TARZAN AND THE MERMAIDS (RKO Radio, 1948), directed by Robert Florey, stars Johnny Weissmuller in what became his 12th and final performance as the Lord of the Jungle, and sixth under Sol Lesser’s production for RKO. While this long running adventure series could have ended here, the Edgar Rice Burroughs character, having been on the screen since the silent movie days beginning with Elmo Lincoln in 1918, would go on vine swinging across the theater screen for another two decades with numerous and younger actors assuming the part, with Weissmuller, on record as being the one most associated with the role, not because he was the best (or was he?), but appearing in more “Tarzan” adventures and longer than any other actor.
