This is an excellent movie about the peasant struggle for land in Chile. I saw it in Rome, Italy in 1975.
I can't remember all the details of the movie but I was blown away by the cinematography, the colorful costumes and the Chilean "Nueva Cancion" sound-track (I think by Inti Illimani or Quilapayun whose music was very popular in Italy at the time). It is one of few movies that made such a deep impression that I remember after nearly forty years not just the title and general theme but at least one scene of peasants on horses with an exciting instrumental accompaniment vividly. I would love to know if this movie is still available for viewing by any medium as I would dearly like to see it again and write a fuller review.
