The National Lampoon’s Vacation film series is a comedy film series initially based on John Hughes’ short story “Vacation ’58” that was originally published by National Lampoon magazine. The series is distributed by Warner Bros. and consists of four theatrical films and one made-for-television spin-off film. In recent years, the series has been the inspiration for various advertising campaigns featuring some of the original cast members. The series portrays the misadventures of the Griswold family, whose attempts to enjoy vacations and holidays are plagued with continual disasters and strangely embarrassing predicaments.
