Addams Family Reunion (1998)

Gomez (Tim Curry) and Morticia Addams (Daryl Hannah) are horrified to discover that Grandpa (Kevin McCarthy) and Grandma Addams (Estelle Harris) have a rare disease that is slowly turning them "normal". The only chance they have of curing them is to organize a family reunion, hoping that someone knows a home remedy. Unfortunately, due to a printing error, the family arrives at the reunion of an ordinary family named Adams (with one D). While Gomez and Morticia, oblivious to the mistake, search for a cure amongst a family divided by the wish to inherit; Pugsley (Jerry Messing) and Wednesday (Nicole Fugere) are busy making new friends...explode; Uncle Fester (Patrick Thomas) and Thing (Christopher Hart) search for a vicious Chihuahua that lives on human hair; and Lurch (Carel Struycken) falls in love. Meanwhile, a couple going to the reunion are given the wrong address and end up at the Addams mansion, where Grandmama (Alice Ghostley) and Cousin Itt (Phil Fondacaro) are staying. No one's life will ever be the same.
