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: After graduating, Jones worked as a TV researcher before stepping in front of a camera. She went on to present a number of programmes on S4C, including Can i Gymru, Salon, and Tocyn. Her big break came in 2010 when she became the co-host of The One Show. Since then, she has co-presented Let's Dance for Comic Relief, and in 2011, she partnered with professional dancer James Jordan on Strictly Come Dancing - they were eliminated a week before the final. In August 2014, she began presenting BBC One celebrity gymnastics contest Tumble. Jones began presenting daytime BBC One series Close Calls: On Camera in 2015 and she started co-hosting BBC series Shop Well for Less? in 2016.

Career: Armstrong made his film and TV debuts in 1994 in There's No Business and A Breed of Heroes. He was introduced to Ben Miller in 1996 and their subsequent success at the Edinburgh Festival Fringe led to their first sketch series in 1997; they've worked together a number of times since on various projects. Armstrong played the lead in short-lived sitcom Beast. He has also appeared in Birthday Girl (2001), I Saw You, TLC, Saxondale, Life Begins, The Trial of Tony Blair, Mutual Friends, Woody Allen's Match Point (2005) and Scoop (2006). Armstrong was the voice of supercomputer Mr Smith in The Sarah Jane Adventures, appeared in the 2011 Doctor Who Christmas Special and has presented the BBC game show Pointless since 2009. In recent years, he has also voiced Danger Mouse in the revival of the animated series and presented Rome's Invisible City, Land of the Midnight Sun and Don't Ask Me Ask Britain.

Career: After attending Birmingham University, Tarrant wrote a series of letters to TV companies which stated "I am the face of the 1970s and you should snap me up now". Eventually he landed a reporting job on ATV, before presenting Saturday morning children's show Tiswas from 1974 until 1981. In the 1980s he took on some entertainment slots on TV-am and began a long career as a DJ with London's Capital FM. Small-screen work has included his own show, Tarrant on TV, The Main Event, Man O Man, and of course, Who Wants to Be a Millionaire?, which became a global phenomenon. He has recently branched out into documentaries with Chris Tarrant - Extreme Railways, and Chris Tarrant Goes Fishing.

Career: Like bread and butter, Giedroyc and Sue Perkins go well together - in fact, they're almost inseparable in professional terms. They were a hit at the Edinburgh Festival in 1993, and went on to write scripts for French and Saunders before presenting comedy chat show Light/Late Lunch and RI:SE. She was also in the children's sketch show Sorry I've Got No Head. More recently she has scored another hit with The Great British Bake-Off, alongside Sue, and daytime ITV show, Mel and Sue. Her radio work has included The 4 O'Clock Show on Radio 4 Extra.
