 "Saturday Night Live" regulars Will Ferrell, Chris Kattan, Molly Shannon, Mark McKinney and Colin Quinn star.

 On the television side, SNL Studios produces "Saturday Night Live" in association with Broadway Video.
 Film productions, typically offshoots of Saturday Night Live' sketches, include, among others, "A Night at the Roxbury" and "Superstar".

 The "Saturday Night Live" sketch spawned two films, and several catchphrases which have since entered the pop-culture lexicon.
 The sketch centered on a local public-access television program in Aurora, Illinois, hosted by Wayne Campbell (Mike Myers, the same actor from "Wayne's Power Minute"), an enthusiastic and sardonic long-haired metalhead, and his timid and sometimes high-strung, yet equally metal-loving sidekick and best friend, Garth Algar (Dana Carvey).
 Wayne lives with his parents and broadcasts his show "live" from the basement of their house every Friday evening at 10:30.
 The first "Wayne's World" sketch appeared in the 13th "Saturday Night Live" episode of 1988/1989.

<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!
