Continuity mistake: At the start, when Aunt Em and Dorothy exit the house, Em holds a basket on her arm, but in the close-up, the basket has vanished as Em adjusts her hat. In the next shot, the basket reappears.
Continuity mistake: Near the start, when Uncle Henry pulls up in the farm wagon in the long shot, the wagon's seat has a high back, but when Aunt Em walks around the horses, the seat's high back is gone, and it reappears when Em sits beside Henry. When they ride away, it briefly disappears, then reappears again.
