William Thomas Hader Jr. (born June 7, 1978) is an American comedian, actor, voice actor and writer.
 He is best known for his work on "Saturday Night Live" (2005–2013), for which he has received three Emmy nominations, "South Park" (2009–present), and his parody series "Documentary Now!
" (2015–present).
Vanya on 42nd Street is a 1994 film directed by Louis Malle and screenplay by Andre Gregory.
 The film is an intimate, interpretive performance of the play "Uncle Vanya" by Anton Chekhov as adapted by David Mamet.
 The film stars Wallace Shawn and Julianne Moore.
Mistress America is a 2015 American comedy film directed by Noah Baumbach.
 It was written by Baumbach and Greta Gerwig, and stars Gerwig and Lola Kirke.
 The film was released on August 14, 2015, by Fox Searchlight Pictures.
Northern Comfort is a 2010 American improvisational film starring Rod Webber and Greta Gerwig.
 Shot primarily in three days for a paltry three thousand dollars, the film is the second of Webber's films based on a manifesto which has been likened to DIY Dogme films which use limited equipment and other resources in an attempt to create an atmosphere of realism not present in most traditional schools of film-making. "
The Boston Globe"’s Ty Burr called it "DIY Dogme dedicated to Webber’s guiding maxim: 'The movie already exists, it’s just waiting to be found.’"
 During an interview for Gerwig's Greenberg starring Ben Stiller (Gerwig's first mainstream movie) she was asked whether she'd be doing more films for $3000 and replied, "[Laughs] Maybe not $3,000 budgets but maybe $50,000 budgets.
 I'm interested in making low-budget films not for the sake of making low-budget films but because a lot of filmmakers that I want to work with and that I like are working on a smaller scale."
A Night at the Roxbury is a 1998 American comedy film based on a recurring skit on television's long-running "Saturday Night Live" called "The Roxbury Guys".
 "Saturday Night Live" regulars Will Ferrell, Chris Kattan, Molly Shannon, Mark McKinney and Colin Quinn star.
 This film expands on the original Saturday Night Live sketches where the Roxbury Guys were joined by that week's host, and bobbed their heads to Haddaway's hit song "What Is Love" while being comically rejected by women at various clubs.
Marie and Bruce is a 2004 American comedy drama film directed by Tom Cairns and starring Julianne Moore and Matthew Broderick.
 It was based on the 1978 play of the same name by Wallace Shawn, who also wrote the script with Cairns, and premiered at the Sundance Film Festival on January 19, 2004.
 Although the film was well received and starred many major motion picture stars, it failed to receive distribution and remained obscure, until it was released on DVD in March 2009.
 The music was done by Mark Degli Antoni, of the band Soul Coughing.
MacGruber is a 2010 American action comedy film based on the "Saturday Night Live" sketch of the same name, itself a parody of action-adventure television series "MacGyver".
 Jorma Taccone of the comedy trio The Lonely Island directed the film, which stars Will Forte in the title role; Kristen Wiig as his love interest/partner, Vicki St. Elmo; Ryan Phillippe as Dixon Piper, a young lieutenant who becomes part of MacGruber's team; Maya Rudolph as MacGruber's dead wife, Casey; and Val Kilmer as the villain, Dieter von Cunth.

<section begin=head />"Saturday Night Live" ("SNL") is a late-night sketch comedy and variety show created by Lorne Michaels.
 It premiered on NBC, a terrestrial television network, on October 11, 1975 under the title "NBC's Saturday Night".
 The show often satirizes contemporary American popular culture and politics.
 "Saturday Night Live" features a two-tiered cast: the repertory members, also known as the "Not Ready for Prime-Time Players," and newer cast members, known as "Featured Players."
 Each week, the show features a host, often a well-known celebrity, who delivers an opening monologue and performs in sketches with the cast.
 A musical guest is also invited to perform several sets (usually two, and occasionally more).
 Every so often a host or musical guest will fill both roles, such as was the case with Britney Spears in 2000 and 2002, Jennifer Lopez in 2001 and 2010, Justin Timberlake in 2003, 2006 and 2013, Taylor Swift in 2009, Bruno Mars in 2012, Lady Gaga in 2013, Miley Cyrus in 2013 and 2015, Drake in 2014 and 2016, Blake Shelton in 2015, and Ariana Grande in 2016.
 With the exception of Season 7 and several other rare cases, the show has begun with a cold open that ends with someone breaking character and proclaiming "Live from New York, it's Saturday Night!
