After a handful of minor film appearances, he played the title role of an Indian boy training a race horse, to win money to build a shrine for his village, in the 1960 film For the Love of Mike (credited as "Danny Zaidivar [sic]"). The same year he had a small role in the classic Western film The Magnificent Seven. In 1962 he played the title character "Ramon", a latino boy featured prominently in an episode of 87th Precinct. He provided the voice of the character Hadji, the Calcutta-raised foster brother of the title character in the well-remembered animated television series Jonny Quest (1964–1965). He continued acting and doing voice work for a few years after its cancellation.
