House of Yes (1997)

A screwball comedy ft a mentally unbalanced Parker Posey who believes she’s Jackie-O. Set during Thanksgiving, her twin brother (Josh Hamilton) arrives home with his new fiancée (Tori Spelling) sending Jackie (Posey) into a delightfully comedic spiral of rage, but she isn’t the only one in the family with issues. Posey is the star of the movie, and the reason I love it. She’s unhinged, dramatic, and delivers every line with perfection (“Were you poor? Did you eat chicken pot pie?”). I love chicken pot pie btw. The writing is so witty I still think about it.
