National Lampoon's Christmas Vacation. Clark Griswold (Chevy Chase) wants to create the perfect Christmas holiday for his family... but that doesn't seem very likely with his family, or him running it! Beverly D'Angelo, Randy Quaid, Julia Louis-Dreyfus and a young Juliette Lewis and very young Johnny Galecki star in this fun and entertaining late 80s comedy that, while not in the top tier of 80s comedies, is still infinitely preferable to what passes for comedy these days.
