Career: While still presenting, Brydon ventured into comedy, and made ends meet by providing voices for adverts and animations. A small role in Lock, Stock and Two Smoking Barrels inspired him to make a short film of his comic characters; series of Marion & Geoff, A Small Summer Party and The Keith Barret Show followed. Other credits include Director's Commentary, Human Remains, Supernova, A Cock and Bull Story, Little Britain, Annually Retentive and Gavin & Stacey. He's also hosted his own BBC chat show and has chaired the comedy panel show Would I Lie to You? since 2009. In 2010, he starred alongside Steve Coogan in the partially improvised BBC Two sitcom The Trip and has since appeared in its follow-up.

Career: His success as a stand-up was crowned when he won an award at the Edinburgh Fringe Festival. He came to the attention of TV bosses after a stint on the radio. Lee was cast in The Sketch show alongside long-term collaborator Tim Vine. After a short-lived stint presenting They Think It's All Over, Mack and Vine began work on Not Going Out. The series revolves around two friends with opposite backgrounds and personalities, much like the two comics themselves. Mack has recently become a regular on comedy panel shows such as Would I Lie to You? and Have I Got News for You. He also has sell-out tours and best-selling DVDs to his name.

Career: After graduating, Mitchell worked an usher at the Lyric Theatre, Hammersmith. He and Webb took a number of shows to the Edinburgh Fringe Festival before being asked to write for Alexander Armstrong and Ben Miller and for surreal comedy series Big Train. In 2001, they made their first sketch show, The Mitchell and Webb Situation, which ran for six episodes on the now-defunct cable channel Play UK. Their next project came in 2003, with the award-winning Channel 4 sitcom Peep Show. They've also worked together on That Mitchell and Webb Sound, That Mitchell and Webb Look and the film Magicians. Solo, Mitchell has appeared on 10 O'Clock Live and numerous panel shows, including Would I Lie to You?, where he's a regular team captain. His autobiography, Back Story: A Memoir, was published in 2012.

Career: Kelly was a news reporter before landing a position as a TV researcher for BBC Scotland in 1983. It was not well paid and she worked as a waitress in the evenings to make ends meet. Despite once being told that her Glasgow accent would prevent her from gaining small screen success she joined TV-am as its senior Scottish correspondent in 1985, but didn't become a household name until she became co-host of Good Morning Britain in 1990. She's hosted her own weekday morning show since 1994; it's been known by various titles but is currently called Lorraine. Other projects include a Sky One show, a regular column for The Sun and her own fitness videos, as well as guest hosting Have I Got News For You and The Paul O'Grady Show.
