Continuity mistake: Rebecca and Crawl are flying home from LA to her farm in "South Dakota" for Thanksgiving. However, when the plane lands, her family is standing in front of a sign that says "Wasco." If you look at a map, you'll see that Wasco California is just outside Bakersfield, which is a mere hour and a half drive north of LA.
Continuity mistake: Crawl is thrown into the manure pile and his hat falls off. Then Theo throws the pitchfork at him and the top tine makes a hole in his hat. Watch the shot closely: the tine on the fork at the top of the screen definitely makes a hole. Later in the day, there in no sign of the hole. Even in the next scene when Crawl is feeding the pigs, the hole is not there. And I can tell you from experience that a pitchfork tine leaves a hole big enough to notice.
Continuity mistake: When Crawl sits down with the log he is about to whittle, there is a large branch sticking out diagonally from the log. When the shot flips to a profile angle, the branch is now sticking straight up.
