The way that "Gordon" took to dancing the Mamushka should have been a tip-off that he was Fester. After all, Gomez said that only the Addamses knew the dance.
I think it was a deliberate hint that "Gordon" really was Fester.
This troper always thought that Thing was some creature that you only saw the hand of, not just a hand.
This troper agrees: In the show, Thing has a lot more forearm and one time you see a second hand- one hand drew into the box and another one popped out to close it. This isn't to say I don't like Thing as he appears in the movie, of course.
In Charles Addams' cartoons, Thing is a creature, not just a hand — in fact, he's a whole other human (or... something like one), usually peering at the Addamses from some vantage point or another. What was unique about him here was that you never fully saw him — he was almost completely obscured by something, or silhouetted, or what have you. Charles Addams originally wanted to make him a disembodied head for the television series.
In the second movie, Gomez tells Debbie that they 'of course they have cable'. This is because after being evicted from their house in the first movie, Gomez became addicted to daytime television shows.
It could also be to get horror films and watch documentaries on serial killers.
In the musical, why is Pugsley the same age, but Wednesday eighteen? In the show, she was six, meaning she would have aged twelve years, so Pugsley should be about twenty to twenty-two years old, but he's still a small (about eight to ten years old) boy!
The musical and the show are in two different continuities.
The reason the Addams act the way they do and seem to kill people with no guilt? The Addams as a whole all have Nigh-Invulnerability and other powers and assume that others do too.
Wednesday's blunt answer to the kid using the Delivery Stork tale: As the eldest, Wednesday has had a front-row seat to parents that cannot keep their hands off one another. She's probably glad she only has two brothers. Plus, Morticia and Gomez don't excessively shelter or fib to the kids, so they probably told Wednesday the blunt truth (albeit, with more tact) when Pugsley came into the picture.
In Addams Family Values, Pubert is born with a mustache like his father Gomez. An episode of the original television show had Gomez mention that he was born with his mustache. Remembering this helps make better sense of this if a mustache is intended to be a proud trait of the Addams Family.
Wednesday acts rather cold to Joel at the end of Addams Family Values. Perhaps it was making up for her rather emotional response to him before she left Chippewa? Someone like her might be a little ashamed of her minor Out-of-Character Moment.
I just figured that was her way of showing emotion (she's an Addams, after all).
There are several hints that "Gordon" really was Fester all along: Granny was able to sense his presence at dinner, he showed the children how to gut with a sword, and how well he danced the Mamushka.
Early in the first film, Morticia tells Margaret that the world needs more widows and orphans. By the end of the film, Margaret is a widow herself.
The reason why Wednesday and Pugsley lap up as much time as they can with their Uncle Fester is because, while it isn't addressed directly, this is the first time that they have met in this continuity.
In Addams Family Values, Debbie has given Fester the present of a bomb. He guesses it as soon as he listens to it, and she gives a flat "What?", not realizing that, as an Addams, he'd actually WANT to get a bomb as a present!
Margaret joining the clan - it shows that the Addamses aren't just welcoming of freaks - they'll take in anybody. In the sequel she has completely adjusted to the family, has married and can interpret Cousin Itt, and has had his baby, and has hired a freak as a nanny. The Addams Clan is not exclusively for weirdos...
Of course it isn't for weirdos, it's for anyone who needs to be loved and to love, no matter how strange, freaky and weird they may be. That, incidentally, is the difference between Margaret and Debbie: both needed love and someone to love, but where Margaret could accept the weirdness and see the loving person under Itt's strangeness, Debbie couldn't see past it-hence Margaret finding happiness and Debbie finding a messy death.
The Addamses family motto is "Sic Gorgiamus Allos Subjectatos Nunc" - "We Gladly Feast Upon Those Who Would Subdue Us". In Addams Family Values, the camp counselors who attempted to subdue Wednesday and Pugsley were shown being roasted alive.
Wednesday says in the first film that homicidal maniacs "look just like everybody else." You could argue that Tully and Abigail were homicidal maniacs as they were willing to kill for their plans and also Debbie from the second movie definitely was and they look just like regular people.
In Addams Family Values, why did Becky and Gary's arduous movie marathon for Wednesday, Pugsley, and Joel ultimately fail to change them? Two of the movies are Annie and The Sound of Music, which have large amounts of what the Addams dislike, but also have the unsavory villains of Agatha and Rooster Hannigan and freaking Nazis, respectively.
In the series, Wednesday was serious but not cynical, however, she was cynical in the movies. Maybe that's because a lot of things she didn't like were going on, and that made her unhappy. When she said "I hate everything", it might have meant that she hated everything that was going on right then.
In one episode, Gomez says that Cousin Itt speaks a different language. In another, Morticia says he talks too fast for people to understand. Maybe it's both. After all, his actor provided the voice by recording gibberish and speeding it up. Cousin Itt probably invented his own language that he taught his family so they understand him, but he believes English is a ludicrous language and doesn't speak it anymore. He also speaks very quickly so when he isn't able to be understood, they reckon "Either they don't speak his language or he's speaking too fast". Add that to the fact that people who cannot speak a language fluently sometimes have difficulty understanding a native speaker who is speaking quickly.
In one of the movies, it's revealed that Fester got his electrical abilities from being struck by lightning. This makes more sense if you realise that maybe Fester was always able to store and exploit electricity, he just hadn't discovered it until being struck by lightning as that was his first experience with electricity.
Maybe Wednesday told the nanny to "be very afraid" because she assumed the nanny enjoyed feeling afraid.
1977's Halloween With The New Addams Family introduced two new children, Wednesday Jr. and Pugsley Jr., who were never heard from again afterwards. Seen in the light of the Addams traditions from the second movie (i.e. when a new baby enters the household, one of the children has to die) - well, that's a nasty possibility, isn't it?
According to The New Addams Family, Pugsley ate one of the kids...
The children in the hospital are probably traumatized for life after hearing Wednesday's parents "had sex".
How is telling a child that two adults had sex horrifying? It's not like they pulled out some porn magazines. Then again, different people have different views on this.
Hell, given all that 'diamond patch stork' crap the kid was spewing, I doubt they even knew what sex was.
Just how much violence and property damage was involved in that summer camp uprising? Did Amanda get burned alive? Perhaps Wednesday and even the other Addams do not realize others are not as difficult to kill as they themselves are.
What did Pugsley do in order to be given probation?
Amanda survived unharmed - at least in body; after nearly being burned alive, who knows what her mental state is right now? Anyway, she's shown in a plane with her parents when Baby Pubert is propelled into the atmosphere.
Did the outcasts really eat the camp counselors?
Is Cousin Itt naked under all that hair?
Are you naked under all those clothes?
Its been implied several times that It IS the hair.
Well, we do know that Itt at least wears gloves.
And it's probably best not to ask how he and Margaret had a child.
More of a Fridge Tearjerker: Fester was gone for 25 years, because Gomez fought him for Flora and Fauna's affection. Gomez is definitely not the kind of man to cheat on his wife, and is so obviously in love with Morticia he wouldn't think of it. He obviously met Morticia after Fester disappeared, and Wednesday and Pugsley were born a few years after. Gomez's beloved brother missed out on the three most important parts of Gomez's life because of Gomez.
A small one, but just think how many times Gomez must have called The Sally Jessy Raphael show for Sally for him to be able to recognise his voice from just two words. They were in that nasty little motel a lot longer than we're shown.
