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: When Jack is handing out presents and the first house he goes to a kid catches him, and he hands him a present. Well you can see the bag of presents right next to the kid, but he never takes it back up, yet has it again later in the movie.
Continuity mistake: When Jack is having his Santa joyride, the army is called in to shoot him down. There is one sweeping shot of the giant cannons rising and firing at him. If you look at the bottom of the screen, you can see two small soldiers as the guns are rising, but as they fire, the soldiers blink out of existence. (00:58:30)
Question: Sally tries to prevent Jack from taking over Christmas using Fog Juice. How will fog stop him?
Answer: Well, it won't. The fog only covered the ground. Because once Jack flew off in his sleigh, he could see. So, it didn't really stop him. He just had to fly above it, and boom! He could see.
Answer: As seen in the movie, the Fog Juice made it difficult to see anything. Sally had hoped that with no way of seeing where he was going, she would be able to stop him from leaving Halloween Town and save his life.
