    Chevy Chase

    The fate of NBC’s Community was one of the more hotly-debated topics of 2012, as series creator Dan Harmon was forced out of production and new episodes were delayed for months on end. One thing that prompted all that drama was star Chevy Chase, who became the enemy of nerds worldwide for his diva behavior on the set.

    Chase not only stormed off when a scene wasn’t written to his liking, he also left profanity-spiked voicemails for Harmon (which were then gleefully released to the press). Eventually, Chevy couldn’t deal anymore and just quit the show, calling it “the lowest form of television.” So what’s better for his career? Apparently doing Old Navy commercials.
