Other mistake: When Uncle Cody hears the bad news on the radio about the banks remaining close, Olivia suddenly orders the children to clear the table when their plates are half full. Which wouldn't happen in a Depression with food being a precious commodity.
Continuity mistake: While Zeb and Cody are on their fishing outing we see that Zeb is wearing white long sleeve thermals under his grey/black shirt. When Reckless starts barking at the catfish, Zeb and Cody head into the water then both men fall in, and Zeb now has red long sleeves under his grey/black shirt, which is presumably a wet suit the older actor is wearing for this wet stunt.
