scripts he submitted earned him a job as a writer from 1995, and within a year McKay became head writer at age 27, a position he held until 2001. He also directed a number of short films for the show, including the original SNL Digital Shorts. McKay encouraged his Second City friend Tina Fey to submit some of her scripts to Saturday Night Live, and she later succeeded him as head writer. Though McKay was never an actual SNL cast member, he did make several on-camera appearances over the years and had a recurring role as an obnoxious audience member "Keith" who would often shout insults at the celebrity hosts during their opening monologue. Shortly after leaving SNL, McKay teamed up with comedian Will Ferrell to form Gary Sanchez Productions and write the comedy films Anchorman: The Legend of Ron Burgundy (2004), Talladega Nights: The Ballad of Ricky Bobby (2006), Step Brothers (2008), and The Other Guys (2010), all of which he also directed, produced and made cameo appearances in as an actor. Ferrell and McKay co-produced the HBO series Eastbound & Down. McKay was one of the writers for the film The Campaign (2012), and produced the film Daddy's Home (2015), the latter of which reunited The Other Guys stars Ferrell and Mark Wahlberg, and was directed by Sean Anders. McKay wrote the screenplay for and directed The Big Short (2015), the film adaptation of Michael Lewis' book of the same name about the financial and subprime mortgage crisis of 2007-2008, and the build-up of the financial and credit bubble; the film starred Brad Pitt, Christian Bale, Ryan Gosling, Steve Carell, Melissa Leo, Marisa Tomei, and Byron Mann. McKay rewrote the script for the Marvel Studios feature film Ant-Man, directed by Peyton Reed. McKay also worked with Reed, Paul Rudd, Gabriel Ferrari & Andrew Barrer on Ant-Man and the Wasp to flesh out the story. He has also expressed interest in helming a Silver Surfer movie for Marvel Studios. He produced the films Land of the Lost (2009), The Goods: Live Hard, Sell Hard (2009), The Virginity Hit (2010), Casa de Mi Padre (2012), Bachelorette (2012), Tim and Eric's Billion Dollar Movie (2012), The Campaign (2012), Hansel & Gretel: Witch Hunters (2013), Tammy (2014), Welcome to Me (2014), Get Hard (2015), Sleeping with Other People (2015), Daddy's Home (2015), and The Boss (2016).
