I read a prior comment and was rather shocked. I was always taught that if entertainment becomes too like real-life, it ceases to be entertainment. That one should suspend one's disbelief for the term of the film - unless the film is claiming to be a documentary or to be of educational value.
Anyhow, I am not a Russian ex-patriot. I'm an American, born and bred. I loved this movie! My father is an History professor. I was well aware that the film was not entirely historically accurate. I will grant you that by 1986, one would wish to have a bit more accuracy regarding the major historical events.
I must disagree that there was a prophetic quality to the 'visionary aspects' of the character Peter the Great. I felt that it came across more as a burning passion. He seemed better educated and thus possessed of a better understanding of what the 'Western European' knowledge/technology could do to help strengthen Russia.
Maximilian Schell is perfect in this role! Although he is a Austrian actor, he is the epitome of a burly Russian Czar.
If you are looking for historical accuracy - look elsewhere. If you are looking for an intense, sweep-me-away drama filled with riveting acting - you've chosen well.
