It’s a madcap, brilliant, and wild film that nearly was lost to the proverbial dustbin of history. The Soviet Georgian film “My Grandmother,” directed by Kote Mikaberidze, lampooned Soviet bureaucracy and was banned a year after its release in 1929. Composer Beth Custer, archivist Steve Seid, and Andrei Khrenov, Russian film historian and nephew of FEK’s founder Leonid Trauberg, discuss the history of the film and its revival.
