For cinephiles, one happy outcome of the Soviet bloc’s disintegration has been greater access to the film and video archives of various police states; this bounty recently yielded the three-hour Romanian documentary The Autobiography of Nicolae Ceausescu, and now there’s this Serbian documentary about Avalon Films, the state-run studio founded by Marshal Tito in Yugoslavia. Director Mila Turajlic never quite decides where she’s going with all her great material; what first appears to be a study of how Avalon misshaped the public’s sense of history largely gives way to an anecdotal narrative about Tito’s movie mania, with copious reminiscences from the dictator’s personal projectionist. But the subject is so rich that Turajlic can’t go far wrong. Particularly fascinating is the story of Avalon chief Ratko Drazevic, who masterminded a series of bloated international coproductions in the 1960s; these projects attracted numerous Western movie stars (Anthony Hopkins, Kirk Douglas, Sophia Loren, Orson Welles), but their real objective was to funnel Western currencies into the government’s coffers. In Serbian with subtitles.
