Chevy Chase
Chevy Chase has a reputation. He is notoriously difficult to deal with, and even more difficult to drink with (he's got a problem with alcohol, but he's getting the help he needs). Despite all of his shortcomings, he is still one of the most important figures on American television.
He's an Angry Grandpa
Chevy Chase isn't getting any younger. Part of his aging has changed his personality to that of a bitter, angry, spiteful old man. When he's not yelling at his costars and taking low blows at them about their real insecurities, he can be found angrily mumbling to himself at the craft table.
