Cinema Komunisto
This eye-opening and bittersweet chronicle of the Yugoslavian film industry recounts how the cinema was used—often with direct intervention from President Josip Broz Tito—to create and recreate the young nation’s history, replete with heroes and myths that didn’t always hew closely to reality.
Starring Josip Broz Tito, Bata Živojinović, Veljko Bulajić, Stevan Petrović, Veljko Despotović, Dragiša Đokić, Aleksandar Konstantinović, Vlastimir Gavrik, Ranko Petrić, Dan Tana
