“Mr. Nobody Against Putin” (in theaters), directed by David Borenstein and Pavel Talankin, is also about thumbing your nose at an authoritarian regime. After the Russian invasion of Ukraine, Talankin, a Russian schoolteacher, was required by the government to teach pro-war messages in his classroom. He and his colleagues were instructed to prove this by filming their lessons. Talankin decides to resist by using his footage to make a documentary on the sly about propaganda in the classroom. He connects with Borenstein — and the result is now an Oscar-nominated film.
