Corrected entry: When Sally is stitching herself up after her escape through the window, she pulls the needle from behind her ear, and then goes to her pocket for the thread. She couldn't have threaded the needle that fast, and she threads it incorrectly. When you thread a needle, the thread is doubled over and tied. The thread Sally uses is a single thread.
Corrected entry: When Jack sings his song on top of that cliff there is a full moon behind him. The next night at the town meeting, the moon is crescent. There would not be that much change in only one night.
Corrected entry: In the town meeting, the big witch is flying around Jack but when the present is pulled by the clown, she is in the seat behind him. (00:21:50)
Corrected entry: There are a lot of small references to Tim Burton's other movies in the movie. The woods that Jack finds the holiday trees looks a lot like the woods Batman drove by in the first Batman. Sally is a person created by someone else just like Edward Scissorhands. The chamber that the boogie man held santa in looks like the place where Danny Devito held Christopher Walken in Batman Returns.
Corrected entry: It is never revealed how Jack and the trick-or-treaters are able to come back through the doors of the holiday towns they visit. It may be that there are other doorways in these worlds, but they are never shown and even if there were, how would they know where to find them in a strange place?
Corrected entry: During Oogie Boogie's song, Oogie has a snake tongue, which snaps at Santa as Oogie sings to him. In the scene where Jack defeats Oogie, Oogie is revealed to be composed of bugs. The snake is not visible.
Corrected entry: During the part where Jack describes Christmas at the town hall while singing the "town meeting song" there is a part where the Mayor is adjusting the spotlight on Jack and the Mayor falls out of movement. One moment he's in one position and the next he's in a completely different position with no range of motion in between. It looks like there was a frame cut somewhere between the moves.
Corrected entry: During the song, "What's This?", Jack knows a bit too much about Christmas. For example: "What's this?/They're hanging mistletoe..." Since the only plants in Halloweentown are poisonous, and mistletoe isn't, how did he know that?
Corrected entry: In the scene when Sally the rag doll is trying to rescue Santa, she uses her unstitched leg to distract Oogie Boogie while her unstitched hands climb down the chain to untie Santa. After Oogie Boogie discovers the trick, he captures Sally. A few scenes later, Oogie Boogie has tied Sally and Santa to a table over a boiling pit, and Sally's hands and legs are intact. Did Oogie Boogie just wait a few moments before tying her up so she could pull herself together?
