Title: National Lampoon's Vacation (film series)
Content:  After the success of National Lampoon's Animal House in 1978, it was decided that another story from the National Lampoon magazine should be adapted into a film. One of such stories chosen for development was John Hughes' "Vacation '58" that was originally published in the September 1979 issue of National Lampoon. Hughes wrote the screenplay for the first Vacation film as "a fairly straight adaptation of the short story", with the exception of the ending that was rewritten and reshot after being "thoroughly despised by preview audiences". In addition to Hughes, Vacation involved the crew of many people connected to National Lampoon. The film was produced by Lampoon co-founder and Animal House producer, Matty Simmons, and directed by Lampoon alumnus and Animal House co-writer Harold Ramis. Released on July 29, 1983, National Lampoon's Vacation proved to be a financial and critical success.
