Revealing mistake: In the last scene, when Chris is leaving, it shows several shots of the peaceful village. Each time they show the village, in the middle of the square is what looks like two boys fighting. One punches the other and he falls down and gets up and punches back and he falls down. They do that about three times.
Revealing mistake: In the scene right after they leave Scar's wigwam, when Ethan and Martin are speaking to each other around their camp you are able to see a small brown dot right above the sandy hills.

Revealing mistake: At the cave near the end, there are several scenes with the secretary of the interior. These scenes with the main actors appear to be filmed in front of the background as they cast shadows on the other film and the lighting is different. This was most likely done because of budget limitations.
Revealing mistake: After GW recruits Bunny to help the chiefs to escape and to acquire rifles and ammo, he comes home asking where the Katie with light red hair is. Katie, excited, goes out on the bedroom landing and sees him at the bottom of the stairs again asking where the woman of the house. Is. Just in back of GW, you can see the shadow of Mrs. Warren waiting to talk to him. Mrs. Warren then appears to try to tell him she was quitting her job.

Revealing mistake: Throughout the film and specifically near the end after Jim has reclaimed Bess and the colt, there are visible horseshoes on the supposedly "wild" horses. While there would logically be a number of abandoned and escaped horses among the herd at any one time, those who joined them in a shod condition would not remain so very long in rugged country. Those born into the wild would never have worn shoes. Reason dictates there would be very few if any horses remaining shod at any one time.
Revealing mistake: In the scene directly after an Indian attack, we see four dead Indians on the ground covered with blankets. The first Indian's blanket is removed to reveal his face and it can be seen that the "dead Indian" is alive and breathing. The blanket over his stomach is moving.
