National Lampoon’s Vacation (1983)

The Griswold Family

The first in a now five-part film series (with one direct-to-video entry and one reboot), the one that started it all. Featuring Chevy Chase, Beverly D’Angelo, Anthony Michael Hall, Jane Krakowski, and the great Imogene Coca, among others.

As mentioned in the episode, the soundtrack by Lindsey Buckingham is awesome, including the quintessential road trip song, “Holiday Road“.
