Nostalgia for the Light

Nostalgia for the Light is a 2010 documentary film by Patricio Guzmán to address the lasting impacts of Augusto Pinochet's dictatorship. Guzmán focuses on the similarities between astronomers researching humanity's past, in an astronomical sense, and the struggle of many Chilean women who still search, after decades, for the remains of their relatives executed during the dictatorship. Patricio Guzmán narrates the documentary himself and the documentary includes interviews and commentary from those affected and from astronomers and archeologists.
