Other mistake: The female journalist is called Samantha Coleman through the movie, but appears in the credits as Samantha Copeland.
Other mistake: Kevin rides down the stairs on his sled and out the door. He originally lined up the sled at the top of the stairs, but it is clear that the stairs lie to the right of the door. His sled went straight down the stairs, therefore making it impossible to go straight out the door in one movement as shown. (00:25:25)
Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Other mistake: At the end of the show when the misfit toys are being delivered, the elf in Santa's sleigh gives an umbrella to each of the misfits so they can glide down with the exception of the bird, who jumps off, apparently forgetting that he is a misfit toy and can't fly; as he stated earlier in the show, he can only swim.
Other mistake: In the scene where Kevin is making the hotel reservation on the phone, the lady does not even ask the dates of when he will be arriving and leaving the Plaza.
Other mistake: When Ralphie and Flick are walking to school for the first time, they meet up with Schwartz, coming down the steps of his house which appears to be two houses down from Ralphie's. Later, when Ralphie is lying in bed after the soap in the mouth scene, the narrator (older Ralphie), states how "Three blocks away, Schwartz was getting his."
Other mistake: In the shot where we see all the terrorists (except Karl and Theo, who are upstairs) walking into the building from downstairs, they are about to walk through a doorway when the camera cuts out. Watch the terrorist on the left (he's the one who guards the door) - the way he's walking he's going to smack straight into the wall! The shot cuts a fraction of a second before he does, but that's not a remotely normal walk/position - it's clearly just because it makes for a cool looking shot. (00:18:15)
Other mistake: 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.
Other mistake: When Chris and Jamie are sitting on Jamie's bed, Tim comes in and shoves Chris onto the floor. This is supposed to be when the yearbooks are switched, but if you watch closely you will notice that Tim leaves with the same yearbook he brought in. (00:03:50)
Other mistake: When James Gandolfini hits Ben Affleck over the head with the shovel for burning something in his front yard, he falls, but his head never hits the ground. You can actually see Ben Affleck holding his head up a few inches off the ground. An impossible feat for someone who is supposed to be unconscious.
Other mistake: Another note about Clark's falling through the ceiling and onto his son's bed: Take note of the shot of him in the attic after falling through the ceiling. He's standing on the upper bunk of the bed now, but from the shot in the attic, he's only down to his knees or so. Assuming his home's ceiling joists are 8 inches or so, then the mattress of the upper bunk would have to be no more than, say, 10 inches from the ceiling for that much of him to still be in the attic while standing on the bed. I've never seen a bunk bed whose upper bed gave you less than a foot of space between mattress and ceiling! (00:33:05)
Other mistake: The story takes place during Christmas time, yet there are still plenty of leaves on all the trees.
Other mistake: After Molly crashes the taxi, she is standing outside in the bitter cold. Yet you never see her breath (vapor) when she is speaking or when she is huffing and puffing when confronted by the wolf.
Other mistake: Rose's secretary tells her that Rose's sister couldn't spend Christmas with her. But in Rose's mother's hospital room, all of the childhood pictures she points out shows a girl and a boy, not two girls. One could claim that they also had a brother, and that there was never taken any photos of her sister, but since the whole story is about the fact that Rose doesn't have anyone to spend X-mas with, wouldn't she call her brother if she had one?
