Seven Kings Must Die (2023 - Netflix) - This movie closes the loop on the Netflix/BBC series the Last Kingdom. If you like historical swords and sandles fare, you will like this a lot. It is really good. It is based on the buildup to the Battle of Brunanburh, one of the more important battles in English history and essentially the final battle in the unification of England's disparate, early middle-ages kingdoms. The movie's plot if complicated, and there are a lot of characters, but it is a good story and the motivations are interesting and credible, leading to the inevitable and very bloody climax at Brunanburh. The historical record is muddled, so no one knows for sure why the events happened, and some things, like King Aethelstan's homosexuality are not known for sure but are pretty likely, but the artistic license taken is well within reasonable bounds and makes the story more interesting. You may need to have IMDB or Wikipedia open to follow the characters, because it gets a bit hard to follow, especially in the beginning.
The lead character, Uhtred of Bebbanburg, is fictional, which he has to be because the show and this movie cover events that occur between 866 (when Uhtred is 10) and 937 (Brunanburh), which would make Uhtred 81 years old at the Battle of Brunanburh. The character in the movie was definitely not 81. That is a small quibble with what is a good and historically accurate movie.
