In National Lampoon’s Christmas Vacation, Clark Griswold (Chevy Chase) gets his wish for a big family Christmas. When his wife Ellen (Beverly D’Angelo) worries that it might not be quite as perfect as he imagines, he says, “Christmas is about resolving differences and seeing through the petty problems in life.” He spends the rest of the movie trying to do just that!

National Lampoon’s Christmas Vacation is based on a short story written by John Hughes titled Christmas ’59. Published in December 1980 it was the second Vacation story to be published in National Lampoon’s Magazine. The first was Vacation ’58, the basis for the first Vacation movie. Hughes would later adapt the short story into a screenplay for the movies.
