Deliberate mistake: At the beginning, the carolers are on the porch singing. The camera never pans, so this means that the carolers are facing away from the house (towards Gate) - seems rather odd. The only reasons for this would have been to make the clean camera move through the crowd and up the house.

Question: How did Gomez and Fester Addams get back up to the first floor from the vault? All they enter was the slides.





Answer: No doubt the Addams house had one of many secret, confusing passageways to get to the higher floors (and other parts of the house) from the vault that the viewer obviously is not privy to.

It made me confused that if there's another secret way up to the house other than the slides or the bookshelf even though Fester had trouble finding which chains to pull but couldn't find the right one, If there was another way into or out of the vault and that means Fester had to know there was if Gomez was with him than Fester would have try the other one too instead of the bookshelf.
