Continuity mistake: The opening scene states the date as April 10th 1865, the day of the train station robbery. Siringo tells Vance at the school money-raising event that the robbery took place 8 weeks ago, but when Clint is buried at the end, his death is April 25th 1865, only 2 weeks after the robbery.
Martha Reno: Clint thinks the sun rises and sets in you.
Vance Reno: I know, Ma. That's just why I'm going.
Vance Reno: Listen, Brett, we didn't steal this money. We took it in battle, fair and square. It's what they call "spoils of war", like capturing a horse or anything else. We didn't know the war was over, and neither did the Federals. So it's still prize money.
