4. 'Animal House'
Long before the title "National Lampoon's" signified a low budget, crap fest of a movie like National Lampoon Presents Dorm Doze or National Lampoon's Van Wilder: The Rise of Taj, it was a mark of impeccable quality. National Lampoon magazine churned out one brilliant issue after the next in the 1970s, and since many of the writers were recent college graduates they decided to write a screenplay based on their own experiences. John Landis signed on to direct the picture and he cast largely unknowns as the students, with the rather large exception of Saturday Night Live star John Belushi. He did attempt to also cast Chevy Chase, Bill Murray and Dan Aykroyd, but they all turned it down. That was a poor decision since the movie became an instant sensation and laid the groundwork for countless 1980s knock-off films about a crazy bunch of college kids that battle an evil dean.
