Other: The little girl elf pours Santa a mug of hot chocolate, but if you watch closely there is nothing in the mug when he drinks it.

Audio problem: When Abby, an elf, is about to tell Santa that Charlie is on the naughty list, she says something about 'Brazilian cocoa beans'. As this line is heard, you can see that her mouth is moving completely differently from the words we hear.

Continuity: After the elves drop the static-free tinsel on everyone, when Bernard and Curtis are discussing telling Santa about the Mrs. Claus, there is tinsel on Bernard's hair, but when shot from the side, the tinsel is not there.

Continuity: In the scene where Santa, Curtis, and Bernard are looking at the mice that have just been duplicated, Bernards brown bag strap is twisted, but in the next shot it is straight. He would have had to take it off to fix it, but he didn't even touch it.
