The Last Outpost (aka Cavalry Charge) (1951)

Set in the West during the Civil War, two brothers are on opposite sides of the war. One (Ronald Reagan) is in the Confederate army while his brother (Bruce Bennett) is in the Union army. Directed by Lewis R. Foster (THE BOLD AND THE BRAVE). A B movie programmer that makes the Confederate army the heroes. The Union army is portrayed as incompetent, the Indians are portrayed as savages but the Confederate army saves the day! It's not even a good B western, just a hash of western movie tropes with a tired romantic subplot (Rhonda Fleming as the girl Reagan ditched when he joined the Confederate army). Surprisingly, the movie was a success and turned a healthy profit. With Bill Williams, Hugh Beaumont and Lloyd Corrigan.
