Tarzan is a fictional character created by the fictional writer Edgar Rice Burroughs in the novel "Tarzan of the Apes" published in 1914. The first Tarzan film was a silent film released in 1918, With the advent of talking pictures, a popular Tarzan movie franchise was developed. Starting with Tarzan the Ape Man in 1932 through twelve films until 1948, the franchise was anchored by former Olympic swimmer Johnny Weissmuller in the title role.
In India, the first Tarzan film was TOOFANI TARZAN produced by Wadia Brothers in 1937 It starred John Cawas as Tarzan. This film went on to become the studio’s biggest grosser. Wadia also made Tarzan an Indian man and never again was his Indian-ness challenged. He always sang and danced and spoke fluent Hindi before the interval.
The next Tarzan film was Zimbo released in 1958. Homi Wadia now created an Indian Tarzan, it was a remake of Toofani Tarzan made a much better Tarzan than Cawas. Perhaps, the reason behind choosing Azad to play Tarzan was his resemblance to Weissmuller. This film became a hit, Azad did many Tarzan films in the 60s. In fact, many Tarzan films were made in the 60s.
