From NetFlix:

Set during the last year of Russian novelist Leo Tolstoy’s life, this biopic explores the fractious relationship between Tolstoy (Oscar nominated Christopher Plummer) and his wife (Oscar nominated Helen Mirren), as he embraces a life of asceticism. Paul Giamatti co-stars as impassioned Tolstoy devotee Vladimir Chertkov, with James McAvoy playing the aging writer’s assistant, Valentin, who is caught in the middle of various struggles.

Leo Tolstoy died in 1910 at the age of 82. The biography in Wikipedia speaks of his deteriorating relations with his younger wife towards the end of his life. Reviews of this film criticize it for “over acting”. But Mirren’s histrionics may well be justified.

We all know Mirren, PLummer, and Giamatti. James McAvoy, who does a fine job, has played in Atonement (2007) , The Last King of Scotland, and State of Play.

Seeing this film in a theatre is worthwhile because the scenery is beautiful. Be sure to stay past the end of the film because you then see actual films made of Tolstoy himself. Remarkable to think that movies were made prior to 1910.
