Potentially the most popular of all of Chevy Chase's films, National Lampoon's Christmas Vacation has become a perennial family favorite despite the Griswolds not actually going on vacation but their extended family visiting them in the suburbs of Chicago during a year where Clark counts too heavily on his Christmas bonus.

With a stand-out performance from Randy Quaid returning as Cousin Eddie, the film layers slapstick chaos with sharp holiday satire. Beverly D’Angelo anchors the madness as Ellen Griswold and new kids Juliette Lewis and Johnny Galecki provide memorable turns.

Written by John Hughes and directed by Jeremiah S. Chechik, the movie captures both the warmth and the frustration of family gatherings, becoming a December staple for generations who can’t help but sympathize with Clark’s doomed quest for the “perfect” Christmas.
