From its title, we might surmise that Armando Iannucci's new film is not exactly being pre-sold as date-night entertainment. Maybe it should be. "Hmmm," teased director Iannucci from the stage of the Alamo Drafthouse Cinema in San Francisco, as he introduced a preview screening of The Death of Stalin. "A story about a delusional narcissistic dictator? Who dies?" Iannucci didn't have to say much more than that, although he did mention his film is now banned in Russia.
