10 Best Bill Hader roles One of the strongest performers to come out of Saturday Night Live in the show’s history, Bill Hader has proven himself to be so much better than his sketch comedy roots. Throughout his eight years on the show, Hader created all kinds of memorable characters (including Stefan, the inimitable New York nightclub enthusiast, who might be one of SNL’s greatest creations) but gave it all up in exchange for a career in Hollywood. He was always destined for greatness, though: even before he made a name for himself on SNL, Hader was giving memorable performances in films and television shows.
