 Mega Mendoeng was screened as late as July 1942 , but may now be lost . Movies in the Indies were recorded on highly flammable nitrate film , and after a fire destroyed much of Produksi Film Negara 's warehouse in 1952 , old films shot on nitrate were deliberately destroyed . As such , the American visual anthropologist Karl G. Heider suggests that all Indonesian films from before 1950 are lost . However , J.B. Kristanto 's Katalog Film Indonesia records several as having survived at Sinematek Indonesia 's archives , and Biran writes that several Japanese propaganda films have survived at the Netherlands Government Information Service .
