Continuity mistake: In the opening sequence, when the stagecoach first overturns, only one wheel is left spinning. In the next shot, as the comancheros ride up to the wreckage, all four wheels are spinning.
Continuity mistake: When Buck and Blue are playing their game on the tree stump, Buck's left hand is down at his side in one shot, then instantly tucked up under his chin in the next.
Audio problem: John and Manolito are driving the wagon and loudly singing "La Gallina" together. But as they pass closer to the camera, we can see that their lips aren't moving.
Continuity mistake: Victoria is wearing a torn white blouse after the stage coach overturns, then, after she and Jim are walking through the desert, and they find water, she is wearing a pristine pink blouse. Then, a later shot shows the white blouse again, and while she and Jim are camping for the night, she is shown changing into the pink blouse.
