While on the set of Gunga Din (1939) in the Alabama Hills, Lone Pine, CA, he was asked by director George Stevens if he could "whip these guys into shape." Being a military expert, Redwng took on the task of training 3,000 Hindus, Gurkhas (Nepalese) and East Indians the military drills of their own nations. The movements of the regiments in the movie are considered classic to this day.
