The film Border (Marz) by Jamshid Heidari is an important film in the history of Iranian cinema. It's the very first fiction film made just some months after the beginning of the war.
It's like a John Ford's films where a small group of civilians represent the nation to fight against the enemy. Heydari managed to elaborate a kind of representation of the Iranian nation at war, right after the revolution.
He also questioned who the enemy is and who the national collectivity is. It's a very complex film. --IMDb
