Continuity mistake: When loading the Lion Chow, Walter's overall strap on his right shoulder is unhooked. When the shot cuts back, it's hooked. (00:41:00)
Factual error: In one shot you will see round hay bails that did not exist during the time period.
Suggested correction: Early round balers, like the one that went into production in 1947 and sold like hotcakes amid the postwar economic boom, produced fairly small bales, which farmers still had to move around by hand.
