Continuity mistake: During the big fight scene at the end of the movie, both Nick and Sato become totally saturated and covered in mud.

It is clear they came directly to the station from the fight, yet there is now hardly any mud on either of them.
Continuity mistake: When the reindeer gets into the house and runs around, it knocks over a TV set. All of the magazines that are on top of the set come crashing to the ground, including a TV Guide with "Get Ready For A Fabulous February" (or something like that) in big letters on the cover. Interesting since the movie is set around Christmas time.
