Revealing mistake: In the scene when Crow Horse and Levoi are running from Coutelle and the "GOONS", they go off-road toward the stronghold. You can see in the grass the tire tracks from all the other takes. Especially as there is no reason any vehicle would leave the road at that place otherwise.

Continuity mistake: After the shootout at Maggie's house and her son is shot, Levoi carries the boy to his car. After he places him in the car, take note of the large circle shaped blood stain on the right side of Levoi's shirt, it is no longer there once they arrive at the clinic. (00:48:00)
Grandpa Sam Reaches: Knock it off! Knock it off! You remind me of a couple of old women.
