Chevy Chase has harbored some regrets about his exit from Saturday Night Live. "It was a mistake to leave SNL," Chase, 82, said in the Thursday, November 20, trailer for the upcoming CNN Films documentary I'm Chevy Chase and You're Not. Chase left SNL in late 1976 in the middle of the sketch comedy show's second season, becoming only the second original cast member to do so after George Coe left during season 1.
