cast by season

Bill Hader is starting his sixth season on "Saturday Night Live."

Originally from Tulsa, Oklahoma, Hader made an early splash on the show debuting his uncanny impressions and characters, including most notably Al Pacino, James Carville, Vincent Price (hosting macabre and inappropriate holiday specials), Dateline's Keith Morrison, and a fan favorite, the clueless Italian celebrity interviewer Vinny Vedecci, grilling such hosts as Drew Barrymore, Seth Rogen, Jon Bon Jovi, and John Malkovich. Hader recently added Stefon, the hipster New York City nightlife correspondent on "Weekend Update," to his repertoire. In 2009, Hader won an Emmy Award for Best Animated Series for his work on "South Park."

Hader has acted in numerous films, including several Apatow productions such as the hit comedies "Superbad" and "Forgetting Sarah Marshall." Hader has also appeared in Apatow's "Knocked Up" and "Pineapple Express." In the feature film "Hot Rod," directed by Akiva Schaffer, he was seen alongside "SNL" castmate Andy Samberg. In 2009, Hader co-starred in Greg Mottola's critically-acclaimed feature film "Adventureland," opposite SNL co-star Kristen Wiig; Hader co-starred in the box office hit "Night at the Museum: Battle of the Smithsonian" with Ben Stiller, and "Tropic Thunder" opposite Tom Cruise. Hader was the lead voice in the 3-D animated film "Cloudy With a Chance of Meatballs" opposite Anna Faris, and he recently completed production on the comedy feature film "Paul," with Simon Pegg, Nick Frost and Kristen Wiig, directed by Mottola, the third collaboration between the actor and director, due out later this year. Hader can also be heard as "The Voice" in the action comedy "Scott Pilgrim vs. The World" starring Michael Cera.
