Rebellion in Patagonia, with Berets, naturally

Rebellion in Patagonia (La Patagonia rebelde) is a 1974 Argentine drama-historical film directed by Héctor Olivera and starring Héctor Alterio, Luis Brandoni, José Soriano and Federico Luppi. It was written by Olivera with Osvaldo Bayer and Fernando Ayala, based on Osvaldo Bayer's renowned novel Los Vengadores de la Patagonia Trágica ("The Avengers of Tragic Patagonia"), which was based upon the military suppression of anarchist union movements in Santa Cruz Province in the early 1920s.

According to a TV interview with the author of the novel, in order to film a scene with a workers protest, the director asked the Santa Cruz governor Jorge Cepernic for extras. The governor then asked the Juventud Peronista (Peronist Youth) to take part. Among those people was Néstor Kirchner, the former President of Argentina (and deceased husband of the present President Cristina Kirchner). 

It was entered into the 24th Berlin International Film Festival, where it won the Silver Bear.
