Goofs

The bull Brennan chose to ride has full horns in bullpen. Horns are cut when Brennan is riding bull.

When Brennan tries to ride the bull, and it's tied down laying on its side and he is straddling it right before he tells the other men to let it up, he grabs its tail, but in the next shot as the men scatter, Brennan is holding onto the rope in front of him with both hands.

Tail jacking is how to keep cattle in general from kicking and struggling. He certainly wasn't going to hang on to it for the whole ride. He very quickly let go and grabbed the bull rope with both hands when it got up bucking.

Brennan approaches the station keeper and his son while riding on a horse with spots that look like they were painted on the sides of the animal, showing large drip marks running down in several places. However, when Brennan next rides into town, his horse's spots are now generally larger, more solid looking and with fewer, more subtle drippy areas showing on its sides.

That type of horse, a claybank, has a gene (Sooty Gene) that actually causes drippy areas and smudges, patches, stripes, spots or dapples.

When Brennan is standing on top of the stagecoach, the clouds behind him change from one scene to the next.

Night time scenes were filmed using a filter to darken scenes. BUT this technique leave the sky blue when in fact the night sky is always black! Further, detail (both close and distant) is evident, when in fact it would, should fade, disappear, into the shadows and darkness of the background.

As Brennan rides into town, after the meeting with the station keeper and his son, he passes the stage, which is standing in the street. Behind the stage, in the street behind, there is a parked car.

Kidnapped Doretta is kept in a mine shack. The flame inside is a smudge pot. Smudge pots were invented in 1911, long after the time frame of the drama.

When Scott gets thrown by the bull he throws himself in the water trough. When Scott surfaces and gets out you can see bulky elbow pads in his shirt, one sleeve is pulled up over the white pad and Scott pulls his shirt sleeve down to cover it.
