Errol Flynn (Custer) graduates from military school but only because the North is desperate for men to join the army to fight the Southern Confederates. His disciplinary record is the worst ever and were it not for the sudden outbreak of war, he surely wouldn't have made it. We follow Flynn's rise through the military ranks until he makes his final stand at Little Big Horn.
The cast are all excellent with the exception of Charley Grapewin (California Joe) who plays one of those comedy drunken wagon drivers who are NEVER funny. He's meant to be an endearing character but he just irritates. There is also an English buffoon thrown in - another cast mis-calculation. But everyone else hits the mark, especially Flynn, Olivia De Havilland as his wife Libby, Arthur Kennedy as his adversary Ned Sharp and Anthony Quinn as Crazy Horse.
There are many good scenes, eg, the confrontations between Flynn and Kennedy regarding the issue of selling alcohol to troops and rifles to the Indians, the final scene between Flynn and De Havilland as he prepares to go into battle for the last time, and the numerous horseback charges that Flynn leads. However, we could do without all the scenes with the stupid wagon driver.
The film has comedy (NOT from the annoying wagon driver), action, drama and good actors that keep you watching despite it's length. Flynn is very likable as Custer and develops his character through to a man of conscience who gives Arthur Kennedy a satisfying pay-back time. What a shame that De Havilland sold Flynn's conditions at the end instead of exposing the corruption that had taken place to the general public. That would have caused the required shame. The Indians are the good guys in this film.
