Other mistake: When "Santa" (Billy Bob Thornton) is in the bar with his mother, the bartender tells him that "smoking is not allowed in here." In the next scene, "Santa" is shown tapping his cigarette on an ashtray. If no smoking, why is there an ashtray?
Factual error: The family supposedly left Ex-Yugoslavia (what part isn't made clear exactly) "because of the war", but the only conflict still going on there in 1999 (when the family is still there in the opening scene) was the NATO bombing of targets in Serbia in order to get the Serbs to lay off Kosovo, and that was long over by Christmas of that year.
Continuity mistake: When Mrs. Lopez calls Allie out as she is working on her illuminated manuscript, the object of her attention drops the pen before turning around. In the next shot he's holding the same pen in hand. (00:04:55)
Continuity mistake: When Scrooge tells Crachit to shut the door because he's letting the heat out, there is nothing in front of Scrooge on the desk, but in the next shot gold coins have appeared.
Continuity mistake: After spotting her dream house Susan runs to the door. As she approaches the house it's not the same building she spotted from the car. (01:23:50)
Continuity mistake: In the scene just before the snowman comes to life, the clock in the hallway reads midnight. But a little later, when he is showing the snowman around the house and he is about to lead him upstairs, the clock reads 8:05.
Plot hole: Billy's not tall enough to impale Linnea Quigley on deer antlers.
Suggested correction: The movie blatantly shows Billy lifting her high enough above his head to impale her. It's literally right there in the scene. Additionally Linnea Quigley talks about the making of the scene in the documentary "In Search of Darkness Part II," and talks about the actor living her high above his head over and over while making the scene.
Continuity mistake: When Santa tells Noelle he's anxious about inheriting his dad's role, the position of his arms is inconsistent between front and side shots.
Continuity mistake: Lucia's hair goes from disheveled to styled during the time it takes for Pia to say (over the phone), "You've gone almost a decade without a single, serious relationship, Lucia." Moreover, Lucia is already applying mascara. It takes longer than 5 seconds to style/fix one's long hair. (00:01:23)
Continuity mistake: Having just reached New York, Langston tries to reach by public phone Reverend Cornell Cobbs. The receiver is in his right hand, until there's a cut to the reverse angle and the phone switches to his left hand. (00:12:30)
Continuity mistake: Susan Lucci's hair color goes back and forth from reddish brown to black in several scenes.
Continuity mistake: When Sheriff Cooper writes "Karsson" and underlines it on the chalkboard, the way it is written changes between shots. In one particular shot, the line he underlined it with is suddenly rubbed out.
Audio problem: As Tom and Mary exit a home that faces the town square, the sound of applause is heard even though almost all the townspeople are holding glasses of lemonade and nobody is clapping.
