Continuity mistake: When Mary falls down the hill, her glasses land in the grass flat against the ground. In later scenes, the glasses are standing up with the arms of the glasses stuck in the grass so that the sun can shine through them to light the grass on fire. (00:49:00 - 00:55:00)
Continuity mistake: After the stagecoach falls and eventually lands, we first see the side of it (where Adam is) and it's fully in the shade. Then, in a later scene, the same side is fully in the sun, and then eventually in the shade again.
