Gentry claimed Cheeta/Jiggs IV was the primary animal actor used in the role of Cheeta in the Tarzan movies. His first appearance as Cheeta is usually stated to have been in the second Johnny Weissmuller Tarzan film, "Tarzan and His Mate" (1934), uncredited as a young chimpanzee riding on the back of the older chimp (Jiggs) who originated the role. He was then allegedly cast in the role himself in the other Weissmuller Tarzans that followed, as well as the succeeding Lex Barker Tarzan films. Journalist R. D. Rosen, who investigated this story, counters that this animal in fact never appeared in any Tarzan film.
