Years before comedians like Chris Farley made their reputations with a particularly physical form of humor, there was John Belushi, the legendary comedian known for iconic performances in Animal House, The Blues Brothers, and as one of the original cast members of Saturday Night Live. Not surprisingly, posters of Belushi as Bluto Blutarsky wearing a shirt that simply says "College" still adorn the walls of countless dorm rooms over 35 years after Animal House came out, and The Blues Brothers is still a cult classic.

Belushi made people keel over in laughter in different roles, but there was always a question of how much of the performance was an act, because Belushi's behavior both on and off the set amazed friends and strangers alike, whether it was through hilarious routines or bizarre antics. Indeed, Belushi's escapades in real life actually provided material for Saturday Night Live skits, including an extended spoof called "The Thing That Wouldn't Leave."

At the same time, however, his abuse of drugs and alcohol made him unreliable to work with, and he quickly forged a reputation for causing headaches on the set. That reputation already preceded him by the time he began working on Animal House in the late '70s, and the delays he caused on The Blues Brothers contributed to making it one of the most expensive comedies ever produced at the time.
