The movie's title is somewhat of a giveaway. The Death of Stalin is a British-French dark comedy loosely inspired by the true story of the chaos that ensued in the Soviet government after dictator Joseph Stalin's death in 1953. The film is a satire of the power struggle that quickly developed in Moscow as Stalin's committee tried to figure out how best to run the country.
"We don't have censorship," Minister Medinsky said in response to the movie's distribution license being revoked. "We are not afraid of critical and unpleasant assessments of our history" (BBC). In the most straightforward sense that might be correct but it's hardly the truth. Journalism has been under threat in Russia and a number of laws, including those supposedly created to combat terrorism, have "[targeted] speech, publications, groups, and ideas deemed 'extremist,' a broadly defined notion interpreted subjectively by officials" (PEN America).
