The 15th screen Tarzan (if you don't count Gordon Griffith) was to have played a Tarzan impersonator in a projected Mike Henry television show, which never materialized. He had been tested fourteen months earlier when Henry got the part. Prior to Tarzan, Ron had numerous parts in movies and television, including the copilot in South Pacific (1958) and had co-starred in TV's brief series "Malibu Run" (The Aquanauts (1960)). He played the title role in the TV series Tarzan (1966), and in two movies made from that series in 1970. He refused to use a stunt double in his vine-swinging or animal fights and was often injured. It has been noted that Ron's physical appearance and dialogue were much more like those of Edgar Rice Burroughs' character than could be said for any other Tarzan. In addition to occasional parts in TV series and movies, several made in Germany, Ron hosted the "Miss America" pageant on television 1979-81, replacing Bert Parks.
