In the film, Custer is correctly portrayed as carrying some sort of early double-action revolver rather than the normal Single Action Army that was issued to the rest of the 7th Cav. While Custer's armament at the Battle of Little Bighorn is not completely known, the general consensus is that he was armed with a .50-70 Rolling Block Remington rifle, as well as his pair of Webley Royal Irish Constabulary pistols chambered in either .422 or .450 that had been presented to him, as well as a matching pair to his brother Tom, by the British some years before.

The movie was given an MPAA rating of PG-13 when Republic Pictures briefly toyed with the idea of a theatrical release during post-production.

It is mentioned by Kate Bighead that Custer cut his hair before the battle, a historical fact. The only other film that mentions that is "Tonka."

The Grand Teton mountains are shown several times in the movie as being in close proximity to the action. In fact, these mountains are in western Wyoming, several hundred miles from southeastern Montana.

While in a tent on the plains with his wife Libby, Custer complains to her that he is 'only a colonel'. In fact, Custer was a lieutenant colonel (LC) at the time, and should have used that complete rank title in this conversation. Although the one word 'colonel' may be used informally to denote an LC, in this case Custer's complaint was specifically directed at his actual rank, so he should have used its full title. (Incidentally, Custer had reached the temporary rank of major general during the Civil War. But like many general officers of that conflict, he reverted to a lower permanent rank after the war ended. It is out of respect for his former higher rank that several fellow 7th Cavalry troopers in the movie address him as 'general').

Some 7th Cavalry troopers are shown with hairstyles from the late 1980s or early 1990s.

Kate Bighead: [Speaking the words of Crazy Horse] One does not sell the land upon which all living creatures walk.

George Armstrong Custer: [to Libby] I didn't matty you for me to sleep in one bed and you in another.

George Armstrong Custer: [Upon realizing he had ran into Crazy Horse's warriors] Oh God. This is not the end of the village. This is the middle!
