National Lampoon’s Vacation, is a 1983 comedy film directed by Harold Ramis and starring Chevy Chase, Beverly D’Angelo, Randy Quaid, Dana Barron and Anthony Michael Hall. The film features numerous others, such as comedians John Candy and Imogene Coca, model Christie Brinkley, and Jane Krakowski, in smaller roles.
The screenplay was written by John Hughes, based on his short story in National Lampoon Magazine, Vacation ‘58 (the screenplay changes the year to 1983). The original story is a (reportedly) fictionalized account of his own family’s ill-fated trip to Disneyland (changed to Walley World for the film) when Hughes was a boy. The success of the film helped advance his screenwriting career.
