The Addams Family

The Addams Family is a 1991 American supernatural black comedy film about a bizarre, macabre, aristocratic family who reconnect with someone they believe to be a long-lost relative. Gomez's lawyer Tully Alford proposes that his son Gordon pose as the disappeared brother Fester to infiltrate the Addams household and find their hidden vault. However, things take a turn when Gomez starts to suspect "Fester" is an impostor, and the family must navigate a series of booby traps and Abigail's sinister plans to break into the vault. In the end, it's revealed that Gordon was actually Fester, who had suffered from amnesia, and the Addams family is whole again as they play "Wake the Dead" with the news that Morticia is pregnant.
