Near the end of the picture, as the good guys make their way back in to town following the clash with the Doniphan's, they're shown heading to Murdock's café, standing alone almost at the edge of the river. However all throughout the picture, Murdock's was right in the middle of town.

The last Apache to attack Harlan knocks the gun out of his hand, then tries to knife him. Harlan's gun can be seen in back in his holster during the fight, then disappears again.

The "Iron" jail cell is made of wooden dowels and boards.

The road the sheriff and the governor are riding on has automobile tire marks.
