Goofs

During the fight in the hotel room between Randolph Scott and Ernest Borgnine, a stuntman obviously stands in for Ernest Borgnine in many of the sequences, as his face is to the camera.

At the end, Scott's character has his duffel bag, but he burned down the hotel/saloon in which he was staying. It would have burned along with the building. EDIT: It wasn't there. He had the whole movie to relocate it.

Jeff Travis (Randolph Scott) goes under the name Mark Stone when he gets a job at the stage line run by Pierre Watkin and Joan Weldon. Weldon calls him Jeff at one point even though he'd introduced himself to her as Mark Stone. Claire Trevor alternates between calling him Jeff and Mark throughout the film.

Sometimes he was Jeff and sometimes Mark. His impersonation didn't hold up for long.

During the fight in the hotel room between Randolph Scott Randolph Scott and Ernest Borgnine Ernest Borgnine, there are multiple times when Slager was down and Travis could have gone for the gun laying on the floor, but instead chose to try to continue cutting at the rawhide binding his wrists with a small knife. He could have also used the knife on Slager, but didn't.

He didn't see any benefit from picking up the gun he because he saw the cylinders were empty from Slager waving it in his face so often. And, that small knife wasn't going to immobilize a big guy like that.

Colt 1873 revolvers were used but the Civil War ended before those revolvers were developed.

When Travis arrives in Prescott, power lines are visible in the background. EDIT: There is no reason to assume they are "power lines". They are probably telegraph lines.
