Movies like "Paths of Glory" and "All Quiet on the Western Front" were truly anti-war. Where the injustices of war were shown on the battlefield, happening to the soldiers, and the senseless killings of thousands by the machines of war and politics were well represented. A good anti-war movie that represented the Civil War I think would be "Andersonville", a movie were I rooted for the Union soldiers when they tried to escape; I did not think it was anti-Confederate either. Other movies that have not been made but could be anti-war would be about the Battle of Franklin or Grant's tactics that killed thousands of his own men. Although it has not been mentioned here, but the movie "Gangs of New York" had a anti-war theme to it, showing how the Irish immigrants were being used as cannon fodder by the Union Army during the Civil War.
