I remember having an American edition of "History of the World". It contained, among other things, short articles about dinosaurs, about the humanoid Lucy from 3.2 million years ago, who was the mother of all humans, and also a short article about King Casimir the Great, although there were no more than a few mentions about Poland. This king improved the tax system, codified the law, established the principles of the judiciary, established the location of many villages and towns, built a number of defensive castles, and founded the Cracow Academy. Thanks to his well-considered decisions, Poland became a wealthy, stable country. And almost all of this was achieved through wise decisions and skillful diplomacy and not the means of war. The filmmakers, Ewa and Czeslaw Petelscy, defined their goals as follows: We would like to bring the viewer closer to the figure of the only Polish king who went down in history with the nickname "the great", to create an image of a ruler, politician, and host, and at the same time show a mentally complicated man, his turbulent personal life. I liked this film a lot and I am giving it only 7 because Casimir the Great is not as well known as some other historical figures, so this biography may not have universal appeal. To me, the assets of this film are careful scenography, interiors, costumes, good acting, and dialogues. The whole film shot on a grand scale. One flaw might be that it is more a series of loosely connected episodes from the life of the king than one whole. But I think that "Casimir the Great" is a very impressive film.
