Matty Simmons, a co-producer of the 1978 megahit “Animal House” and longtime publisher of the magazine that spawned it, takes a fond look back on the “little movie” that turned into a blockbuster, made John Belushi a star, and spawned dozens of badly made imitations. As the moneyman behind the success of the legendary National Lampoon, Simmons draws from exclusive interviews with actors including Karen Allen, Kevin Bacon, Peter Riegert, and Mark Metcalf, director John Landis, fellow producer Ivan Reitman, and other key players-as well as behind-the-scenes photos-to tell the movie's outrageous story, from its birth in the New York offices of the National Lampoon to writing a script, assembling the perfect cast, the wild weeks of filming, and, ultimately, to the film's release and megasuccess. This is a hilarious romp through one of the biggest grossing, most memorable, most frequently quoted, and most celebrated comedies of all time.
