The baby's name, Pubert, was the name originally suggested (and rejected) for Pugsley by Charles Addams when he was asked by the producers of The Addams Family to name the hitherto unnamed characters in his cartoons.
David Krumholtz's character says at one point he has every card for his Serial Killer Card Collections "except Jack the Ripper and that Zodiac Guy." Jack the Ripper and The Zodiac Killer are the real world's most famous uncaught serial killers.
The book that Joel Glicker (David Krumholtz) is holding when he enters the Harmony Hut only for it to be taken away is Stephen Hawking's "A Brief History of Time".
Wednesday bitterly quips that "Chippewa" in Camp Chippewa means "orphan". This is pure sarcasm; Chippewa is actually a form of the name Ojibwa (a Native American nation), the original meaning of which is unknown.
After Fester gets his "makeover", his clothing and hairstyle closely resemble those of mad scientist Dr. Janos Rukh, the character played by Boris Karloff in The Invisible Ray.
Michael Jackson was signed on to write and perform a song for the film's soundtrack and to promote it with a video. Although he was able to finish the song, contractual difficulties coupled with the child molestation allegations made against Jackson resulted in the song being dropped from the soundtrack, and the video was never filmed. The song, "Is It Scary," was later included on Jackson's 1997 'Blood on the Dance Floor: HIStory in the Mix' album and was also used in his short film '_Ghosts (1997/I)_'.
Adding more than just make up to the character, Morticia Addams is always lit separate from everyone else in a scene. Her lighting always consists of one beam of light across her eyes that gradually fades outward to add to her grim look.
Nathan Lane has a cameo as a police officer in this movie. He would later go on to portray Gomez Addams in the 2010 Broadway musical version of "The Addams Family."
When Fester announces his engagement, Morticia makes an overt reference to the ring worn by Debbie being the same one in which Fester's grandmother was buried. Debbie slyly whips out a shovel, adding a literal component to her character's "golddigger" status.
David Krumholtz played head elf Bernard in the first two The Santa Clause movies with Tim Allen. Joan Cusack (villian Debbie), Sam McMurray (Becky Buckman's father Don), Kaitlyn Hooper and Kristen Hooper (who both play Baby Pubert) would all go onto to act along side Tim Allen as well. McMurray and the Hooper Twins had guest spots on Tim Allen's sitcom Home Improvement. Cusack plays Jessie the Yodeling Cowgirl in Toy Story 2 and Toy Story 3 with Allen's Buzz Lightyear (Cusack and Allen's characters are love interests.). Tony Shalhoub, who plays Jorge the sailor in the "Macho Man" scene, would later star alongside Allen in Galaxy Quest.
While being brainwashed at camp, one of the films that Wednesday and Pugsley are made to watch is the musical Annie, directed by Anjelica Huston's father, John Huston. That film also featured Tim Curry, who went on to play Gomez Adams in Addams Family Reunion.
Not only is Gary's play puerile and under-dramatized, it's historically inaccurate. The Chippewa are from the Midwest. Pocahontas was a Powhatan, which are indigenous to Virginia. Neither she nor the Chippewa would have bee present at the first Thanksgiving. Moreover, by 1621 (the first Thanksgiving), Pocahontas had married John Rolfe, moved to England, and subsequently died.
