Korda had read and been so impressed Kipling's 'Toomai of the Elephants', that when documentary director Robert Flaherty came to him for backing, he readily gave it to him and sent him to India in February 1935. After over a year with nothing productive been done, Korda sent director Monta Bell to help out. and then Zolta Korda. By Summer 1936, with over 55 hours of background footage and still no story, the crew were brought back to Denham Studios . Writer John Collier was brought in to produce a simple script for Zoltan to shoot in the studios and on location on the River Colne.

This was the first film to star Sabu, who was discovered by cameraman Osmond Borrodale working as a mahout for the Maharajah of Mysore, and. who went on to become a major star.
