Addams Family Values (1993)

This is an okay movie. Gomez (Raúl Juliá) and Morticia Addams (Anjelica Huston) welcome the birth of their third child, Pubert. Wednesday and Pugsley do not like their new baby brother and try several schemes to maim him. Their parents decide they need a nanny to keep the children safe. Most of the applicants are immediately scared off by the family, but finally Debbie is hired. Her real intention is to marry the wealthy Fester and steal all of his money. She convinces the family to send the two older children away for summer camp.

This is the sequel to the The Addams Family (1991). The baby Pubert Addams was actually played by two sisters.
