When the Durango Kid shot the outlaw guarding the rifles in the stagecoach, he was chasing it from behind and the man in the stagecoach was sitting with his back to the rear of the coach. When he was shot, the man clutched his chest, so not only did Durango hit him in the chest from behind, but the bullet would have had to make a ninety degree left turn into the stagecoach.
Ace Brockway told Smiley Burnette that he would owe a dollar for every glass he broke doing the tablecloth trick, so when Smiley failed with fifty eight glasses, he owed Brockway fifty eight dollars. But only a couple of glasses were visibly broken.
The stagecoach carrying the rifles at the 24:45 mark is labeled "Butterfield Stagecoach Express," but a minute later when the Durango Kid rides alongside it and leaps aboard it reads "Overland Stage Lines," but the words read backwards, indicating the use of stock footage the producers tried to disguise by flipping the image.
