Chevy Chase
National Lampoon and SNL star Chevy Chase has a pretty tumultuous history in Hollywood. Despite being one of the most in-demand comedy actors in the 1970s and 80s, he was a trainwreck of a person to work with. He had troubles with addiction and was known for being callous (and sometimes racist) on set. Despite being a funny guy, he doesn't know how to take a joke, and hated his time during a celebrity roast.
