Wong brothers [SEP] Introduction
The Wong brothers were three ethnic Chinese film directors and cameramen active in the cinema of the Dutch East Indies (now Indonesia). The sons of an Adventist preacher, the brothers – Nelson (1895–1945), Joshua (1906–1981), and Othniel (1908–1986) – received much of their education in the United States before going to Shanghai and establishing The Great Wall Productions. By 1927, Nelson had arrived in the Dutch East Indies and was working with Miss Riboet's Orion, a theatrical troupe. When its owner Tio Tek Djien suggested he make a film with the troupe's star, Nelson insisted that his family be brought to the Indies.
