Probably wouldn't be able to make a movie that was honest about how "The Noble Savage" actually lived and fought.
Butler bought 12 guns used them on very limited basis. They were removed due to their impracticality in the trenches. They were not adopted by the U.S. Army until the late 1860's.LMCane said:
There were no Gatling machine guns used in the Civil War except in the trenches of Petersburg (due to the size and complexity and the waste of ammunition which was in short supply)
and the Union would not have shot prisoners of war who were regular Confederate soldiers wearing uniforms and in organized units (they would shoot Mosby's Rangers who were guerilla units)

I've always thought that Harald Hardrada's life would be a smash hit - The Last Viking.
Something set in the Roman civil war between Sulla and Marius could be fun too.
