Phantoms of the Sierra Madre

"In 2016, Danish writer Lars K. Andersen released a film inspired by his childhood hero, Norwegian explorer Helge Ingstad, who in 1937 embarked on an expedition in search of an Apache tribe in Mexico. Norwegian filmmaker Håvard Bustnes follows Lars as he meticulously reconstructs Ingstad's path, driven to uncover the secrets of the lost tribe. Alongside Pius, the great-grandson of Apache guerrilla leader Geronimo, they confront a Mexican family and an intelligence agent, while Lars grapples with the moral dilemma of pursuing a tribe that does not wish to be found and ultimately recognizes his imperialistic and colonialist perspective. This is how the film gradually becomes a profound critique of cultural appropriation, indigenous exploitation, and colonization."
