Nicole Fugere, who played Wednesday Addams, was the only cast member from Addams Family Reunion to return for this series.

John Astin, who originated the role of Gomez Addams in the 1960s original series, appeared in a recurring role in later episodes as Grandpapa Addams, Gomez's grandfather.

Glenn Taranto, who took over the role of Gomez Addams, was a fan of the original show and modeled his performance on John Astin's portrayal of the character.

The series reworked several storylines from the original 1960s Addams Family show while adding modern elements, jokes, and references to the earlier episodes.

Unlike the original series where Fester was Morticia's uncle, this show followed The Addams Family film's approach by making Fester Gomez's brother.

Wednesday and Pugsley were given expanded roles highlighting violent and sadistic personalities, a trait popularized by The Addams Family film rather than the original 1960s series.

The new theme song departed from the classic tune, keeping the finger-snapping but at a faster pace, with characters Lurch and then Gomez saying 'snap' twice in rapid succession; it was written by Barron Abramovitch, Jeremy Sweet, and Michael Whittaker.

A Game Boy Color game based on the series was developed by 7th Sense and released in Europe in 2001 by Microids, while a planned American release by Titus Interactive under the same title was cancelled.
