The National Lampoon’s Vacation series is a beloved comedy franchise, but it has been up and down in terms of quality. The series kicked off in 1983 with National Lampoon’s Vacation, starring Chevy Chase and Beverly D’Angelo as Clark and Ellen Griswold taking their kids Rusty and Audrey on a road trip to Walley World. Chase and D’Angelo reprised their roles in three direct sequels – European Vacation, Christmas Vacation, and Vegas Vacation – before Randy Quaid took the lead role of a made-for-TV spin-off, Christmas Vacation 2, and Ed Helms played an older Rusty taking his own family to Walley World in 2015’s nostalgic legacy sequel, simply titled Vacation.
