I have grievences. All in all an epic piece of work. Cut to the Pawnee attack on the village, and I'll be damned if one of the Pawnee isn't wearing a pattern 1880 Cavalry greatcoat. The movie takes place in 1863.
For the uninitiated, greatcoats were sky blue inside and out from the war with 1858, up to 1880 when Branch of service colors were added to the cape lining.
Another little detail is one reviewer says the movie takes place near the end of the Indian wars... Which wouldn't end untill well into the 1890's or 1980's!
