In 1976 the creators of National Lampoon, America's most popular humour magazine, decided to make a movie set on a college campus in the 1960s. They called it Animal House, and the story they produced was rejected and ridiculed by Hollywood studios - until at last Universal Pictures agreed to produce the film with a tiny budget. The hilarious, unforgettable movie they made would become one of America's most beloved comedy classics. It launched countless careers, made a household name of John Belushi, and paved the way for today's comedies from directors such as Judd Apatow and Todd Phillips. Bestselling author Matty Simmons was the founder of National Lampoon and the producer of Animal House. In Fat, Drunk, and Stupid, he draws from exclusive interviews with actors including Karen Allen, Kevin Bacon, Peter Riegert, and Mark Metcalf, director John Landis, and fellow producer Ivan Reitman - 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 mega success.
