The motion picture enterprise of the Nationalist Army played an important role in modern Chinese history, but the exact role the authorities and political and military circumstances played is an unknown area that leaves a lot to be probed into and charted. The filmmaking business was in fact established in the military system since the start-up age of the Nationalist Army-an achievement in military propagation that defied most of nations during that time. During the age of Japanese invasion, the military ”China Film Studio” became the largest filmmaking company in the homefront, churning out lots of newsreels and dramas. In order to show movies in the rural area, a propagation troop was organized and dispatched to the villages. It's significant in an age when movie was rare outside cities. In order to understand the boom of filmmaking during this time, foreign influences must be factored in. Russia, Italy and U.S. propagation policies were all resources that inspired the authorities in the practices of filmmaking. However powerful the filmmaking in propagation was, it's not unbridled. The red tape that paralysed many bureaucracies also infested military departments, neutralizing the effects the propagation could make. This paper focuses on how the Nationalist government, especially military departments, promoted the filmmaking business since 1920s. In an age that movies are flourishing as ever before, the history of filmmaking as accounted here shall be inspiring to those who are interested in its present and past.
