After the 1973 coup that put an end to the socialist government of Salvador Allende, most Chilean filmmakers went into exile. Dispersed all over the world, they made more than two hundred fiction films, documentaries, animations, videos, and works for television. José Miguel Palacios builds upon extensive archival research to trace a transnational history of this radical cinema, beginning with its emergence out of global solidarity networks in the 1970s. Chronicling the dangerous efforts to smuggle film reels out of Chile, the discourses of political cinema these films inspired as they traveled between film festivals, and the prints’ unfinished process of return to Chilean archives and museums over the past two decades, Transnational Cinema Solidarity offers a politicized understanding of world and transnational cinema that emphasizes geopolitical relations and cinematic alliances based on solidarity.
