The first breakout star of SNL, Chevy Chase defined the show’s initial tone with his smug, pratfall-prone coolness and his iconic ‘Weekend Update’ catchphrase, ‘I’m Chevy Chase… and you’re not.’ His portrayal of a clumsy, bumbling Gerald Ford set the template for all future political impressions on the show. Despite leaving after only one season, his impact was monumental. He immediately launched into a successful film career with hits Caddyshack, Fletch, and the National Lampoon’s Vacation series. While his reputation has been complicated over the years, there’s no denying that his brief, meteoric tenure at SNL made him the show’s first true superstar.
