#1293 Stars and Bars (1988)
A somewhat annoying art expert (Daniel Day-Lewis) married to an annoying spouse while working for annoyingly demanding boss is send to deep south to purchase a painting from an annoying eccentric hillbilly family whose annoying unmarried son living at home does annoying things to prevent the sales.
The only thing not utterly annoying in the cast of Stars and Bars is the head of the family, played by Harry Dean Stanton who plays the only character in the movie with some dimensions written into it, and Stanton has the acting chops to make his character likeable despite all of its weird personal traits.
