Surpresas do Amor

During the filming of the dinner sequence, Reese Witherspoon was hit in the face with a ceramic plate and required five stitches, which delayed the shoot for three days.

During the Taboo game, Denver answers "What is the capital of China?" with "Hong Kong". This is part of the joke. Denver and his wife, who obviously have little education, think that Hong Kong is the capital of China. The point of the game was for Denver to guess that "Hong Kong" was the answer on the card, which he did. The point of the scene was to demonstrate how well they knew each other and how poorly Kate and Brad knew each other. The fact that Denver got "Hong Kong" from "What is the capital of China?" helped to make that scene funny.

The French release, distributed by Metropolitan Filmexport replaces the opening title card with one featuring the French title "Tout...Sauf En Famille" (which translates to Anywhere...Except Amongst Family) instead of having the original English title and subtitling it with the French one as is more common. Also, while an English title is displayed during the end credits, that one is not "Four Christmases" but "Anywhere But Home", the international English title for the film.
