The new CNN documentary I'm Chevy Chase and You're Not revisits Chevy Chase's controversial exit from Community in late 2012. Chase notoriously departed the NBC sitcom midway through its fourth season after a series of creative clashes with Community creator Dan Harmon and an alleged on set meltdown. His feud with Harmon reached a boiling point when the writer allegedly asked the cast and crew of Community to chant "F*** You" toward Chase and his family at the season 3 wrap party in April 2012. Harmon was fired at the end of season 3, though trouble on the Community set only intensified.
