Continuity mistake: When we see Christmas Flint with her dad and Miss Rayleen for the first time, she's watching them bicker, her chin perched on the back of her hand. Which hand, though? It's her left hand for the greater part of the scene, but in the shot when Jim Gaffigan is saying "I got to find my pants. You move my pants?" it's the right one. (00:05:00)
Factual error: Drinking a juice box in 1977. They didn't appear in the US until 1980.
