Armando Iannucci, the caustically comic creator of Veep, directs and is the co-author of this 2017 political dark comedy. How dark? It’s about the power grab surrounding the expected demise of Soviet leader Josef Stalin – and includes facts and observations to make the movie a study in scary despotism. And yet, it’s big on laughter, too – and features, among others, Jeffrey Tambor, Michael Palin, Simon Russell Beale and Steve Buscemi.
