Sorin's movie is based on a true story.
In 1972 Juan Fresán,a very creative man from the advertising world, began filming "La Nueva Francia" a film that would tell the story of Orélie Antoine de Tounens, a French madman that proclaimed himself King of Patagonia. The project was described as un "underdeveloped superproduction".
The project failed, as it fails in Sorin's movie, due to lack of funds and also because in 1974 Fresan had to go to exile.
Sorin had been the cinematograpehr of La Nueva Francia and based on that experience he began his own project.
Fresan never approved Sorin's project.
Some footage of La Nueva Francia was found by Fresan in 2004 the same year he died a few months later.
That footage including interviews to people involved in the project, including Sorin,was turned into a documentary film by Lucas Turturro called Un Rey para la Patagonia, that premiered in 2011
