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: 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: 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: Kielty's stand-up career began in 1992. He was a finalist on the Late Late Show New Comedy Act of the Year, and co-founded one of Northern Ireland's first comedy clubs at the Belfast Empire. In 1994 he hosted BBC Two special The Empire Laughs Back. Big break came in 1995 when he stole the show on St Patrick's Night Comic Relief in Belfast. Following his live series PK Tonight, he went on to appear on The Stand-Up Show and The Big Breakfast. His other credits include After The Break, The National Lottery Big Ticket, Fame Academy, Celebrity Love Island and his own chat show, Patrick Kielty Almost Live.

Career: After appearing on stage for many years, Cribbins finally made his film debut in 1957's Davy, before going on to work alongside some of British cinema's biggest names in such films as Two-Way Stretch, She, Daleks' Invasion Earth 2150AD, Casino Royale (the 1967 version), and Frenzy. He's also starred in several Carry On movies. Cribbins has also worked extensively in projects aimed at youngsters, making a record number of appearances on Jackanory (17), voicing The Wombles, and appearing in The Railway Children. More recently, he's featured in Coronation Street and the revamped Doctor Who. Over the years, he's also had his own TV show and three hit records, including Right Said Fred.

Career: After leaving school, Deborah studied business at Brighton Technical College, during which time she also worked as a salesroom model in a fashion house. After graduating, she moved to Italy to set up a glass and ceramics export agency, which sold products to high-end retailers including Harvey Nichols. The company failed after just 18 months. But she went on to have several successful leisure and retail businesses. In 1988, she joined her family's business to run its amusement arcade operations, and in 1992 she began working for holiday park operator Weststar Holidays. She led a management buyout of the company in 1999 and sold it in 2005 in a deal worth £33 million. She is most famous for her appearances as a "dragon" on the BBC programme Dragons' Den. She took over from Rachel Elnaugh in 2006. In September 2013, she was a contestant on Strictly Come Dancing.
