Great films rarely arrive as unheralded as "The Battle of Chile" did in 1975, a two-part, three-hour-and-ten-minute documentary about the events leading to the fall of Chilean President Salvador Allende. This film doesn't even present itself with fanfare, and it takes a while to get going. It opens in March of 1973 with inquiring reporters asking people how they're going to vote in the coming congressional election, which amounts to a plebiscite on the Allende government. The election is taking place after Allende has been in office for over two years and has been trying to reorganize the society and move it toward Socialism within the framework of democratic government. His Popular Unity coalition was put into office with only a third of the popular vote, so he has been on shaky ground. His efforts to nationalize certain industries have brought on a squeeze from the banking and industrial community and from foreign interests (especially the United States), and Chile is suffering economic deprivations.
