The Hour of Liberation Has Arrived(1974)

Overview:

In the late 1960s, Dhofar rose up against the British-backed Sultanate of Oman, in a democratic, anti-imperialist guerrilla movement. Director Heiny Srour and her team crossed 500 miles of desert and mountains by foot, under bombardment by the British Royal Air Force, to reach the conflict zone and capture this rare record of a now mostly-forgotten war.
