We preview the latest documentary in the PBS series P.O.V. - "My Perestroika" explores the dramatic changes in Russia by focusing on the experiences and perspectives of five Russians who grew up at the very end of the Soviet era and who have lived through the tumultuous years of Gorbachev, Yeltsin and Putin. We speak with the film's director, Robin Hessman, whose impressive resume includes a stint producing the Russian version of Sesame Street (which we also discuss.)
