In this award-winning documentary, producer and director Peter Miller uses an impressive collection of film clips and interviews to illustrate the connections between emotion, social politics, and music in the song “The Internationale.” Miller traces the history of this song as a rallying point for workers, activists, socialists, and communists, from its beginnings in the Paris Commune in 1871, through the Russian Revolution, the Spanish Civil War, labor struggles in the United States, and Tiananmen Square, to its recent reworking and revival by British musician Billy Bragg. The power of this documentary is its focus on the potent solidarity and optimism that “The Internationale” has inspired in workers and activists around the globe. Due to its combination of musical and social history, in addition to its accessibility, this film has the potential to reach a variety of audiences. It is suitable for public television broadcast and as an educational resource either for the classroom or for an activist or labor meeting.
