Robert, I had not heard of Tempest (aka La Tempesta), and I'm so glad you mentioned it! I checked it out on IMDB and here's a comment from another fan of the film:
I first saw Tempest as an 8-year-old; I was also an altar boy in my Russian Orthodox parish in Pennsylvania. While others watched a story on a large screen, I found myself pulled into the action, and to be honest, I did not sleep well for the next two weeks. But this attests to the movie's impact in an ultimately affirmative way. One week later we visited the Gettysburg Battlefield, and my father's unspoken wish that I fall in love with history came true.
I cannot overstate the film's influence on my life - I taught history for three decades and earned my PhD in education while doing so. 28 years later I was asked to recount the key points of the story and I spent nearly thirty minutes doing so in incredible detail. I became a devoted fan of Van Heflin and Agnes Moorehead. I also began to probe in depth the complex history of my mother's homeland and began to admire Alexander Pushkin's genius. I spent years trying to obtain a copy of the film and finally did so only last week; I found a wealth of material for psychological studies simply in comparing my recollections with what the film actually presented.
I did not expect to find such fidelity to historical and even cultural accuracy, and I regret that many movie-goers at the time were probably not prepared for the insights that Pushkin, via Tempest, offered them. The climactic battle scene illustrates the division of the Cossacks, especially on the eve of the faraway American Revolutionary War, into factions: one of these supports the crown, even if it rests on the head of an Austrian-born czarina, another reacted to the evils of czarist autocracy, and yet another wished only to live undisturbed and draw upon its traditions to assuage the misery of struggling to survive in equally hostile natural and political environments.
Perhaps only the diminished quality of my copy impels me to rate the film 8 instead of 10; certainly a production which so influenced my life, and therefore quite possibly many others, deserves respect equal to the very simulated but overwhelming post battle impact it had upon me.
So I'd say that's a definite thumbs up!
Like you, I'm a fan of Agnes Moorehead. If you've seen The Swan you know that although she's only in a few scenes, prior to her arrival we can feel her presence by the way the others react to the mere mention of her name! I like to think that her brisk and intimidating Queen Maria Dominika--as conceived by the playwright Molnar, the screenwriters and Moorehead herself--might have been influenced by Queen Victoria's own formidable personality during her "Grandmama Queen" years.
Also, I recommend the Wikipedia bio re: Agnes Moorehead. It is a pity that most people know of Moorehead only as Endora, although certainly Endora was a memorable creation!
