A Spark Can Start a Prairie Fire is a 1961 Chinese documentary directed by Fu Ya and Huang Bao-Shan. As described by Erik Barnouw, it was assembled in Peking using footage from many sources in China and abroad to document the evolution of the People’s Republic of China. Another source notes that it looks back on 34 years of the People’s Liberation Army. The title comes from Mao Zedong’s famous quote: “A single spark can start a prairie fire,” symbolizing how small revolutionary actions can grow into a broad movement.
