The movie is fantastic -great plot, superb acting and characterization, fantastic sets, costumes and music. BUT It is historically very inaccurate - Peter suffered from bouts of temporary insanity. Far from betraying him his first wife was madly in love with him and bombarded him with love letters througout his European tours. Also ironically (remember Omar Sharif's comment on Peter being strong and Ivan weak) most of Peter's twenty something children died in infancy - Ivan produced a flock of children and grandchildren.
