Bobcat Goldthwait doesn't make movies for morons "When you make a comedy now, if it's an R-rated comedy, it's really trying to get 13-year-old boys to buy it or see it," said Bobcat Goldthwait, writer and director of the new R-rated comedy "World's Greatest Dad." So does that thinking mean Goldthwait tailored that film to appeal to this big ticket-buying demographic? Um, not so much.
