In 1962, Mahoney became the 13th actor to portray Tarzan when he appeared in "Tarzan Goes to India", shot on location in India. A year later, he again played the role in "Tarzan's Three Challenges", shot in Thailand. When this film was released, Mahoney, at 44, became the oldest actor to play the jungle king, surpassing Weissmuller and P. Dempsey Tabler, a record that still stands. Dysentery and dengue fever plagued Mahoney during the shoot in the Thai jungles, and he plummeted to 175 pounds. He needed a year and a half to regain his health. Owing to his health problems and the fact that producer Weintraub had decided to go for a "younger look" for the apeman, his contract was mutually dissolved.
