The Nutt House, initially titled The Nutty Nut, is a 1992 comedy film directed by Adam Rifkin.

Philbert is married to a wealthy heiress with a mistress and a political campaign for President of the United States.

Nathan suffers from a severe case of multiple personality disorder and has spent his life in a lunatic asylum.

Nathan shows up on his brother's doorstep and what begins as a case of mistaken identity spirals out of control.

Entertainment Weekly and TV Guide both panned The Nutt House, with the former writing that "the plot of The Nutt House, such as it is, serves merely as an excuse for uninspired slapstick that makes Pauly Shore look like Buster Keaton.
