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: Gorman followed up his breakthrough success with other similarly zany projects. His astrology experiment saw him living his life entirely at the whim of his horoscopes, while his googlewhack adventure saw him travelling the world to meet people whose websites possessed the mysterious "googlewhack" - returning just one search result on the website Google. In 2003, he was listed as one of the 50 funniest comedy acts in The Observer, and he is a regular performer on Radio 4. He also regularly appeared on the BBC Three show Rob Brydon's Annually Retentive, and presents a TV version of his own radio show, Genius. He continues to tour as a stand-up comic.

Career: Davina started out as a singer (her demo was produced by Eric Clapton) and worked for the Models One agency before securing a presenter's job on Ray Cokes' Most Wanted on MTV Europe. ITV's middle-of-the-night series God's Gift led to the higher profile Streetmate, Don't Try This at Home and Popstars: The Rivals, although she tasted failure with her sitcom Sam's Game, series He's Having a Baby, and her self-titled BBC chat show. She's also fronted Love on a Saturday Night and co-hosted both Sport Relief and Comic Relief. Big Brother remains her biggest hit (she quit after 11 series as host in 2010), but has another hit on her hands with The Million Pound Drop. In August 2013, she began presenting ITV's dancing reality series Stepping Out, and in January 2014 began co-hosting Channel 4 reality series The Jump alongside Alex Brooker. The following month she ran, swam and cycled her way across the UK for Sport Relief.

Career: Street-Porter's first job was as a writer for a girls' magazine. She then worked on the Daily Mail and various glossies. In 1973, she featured on LBC Radio, before hosting TV's The London Weekend Show. Eight years later she became a producer, then became responsible for around 35 series at the BBC. In 1995, she helped set up short-lived TV station L!ve TV. In 2004, she took part in I'm a Celebrity... Get Me Out of Here! She's also appeared in So You Think You Can Teach, So You Think You Can Nurse, Deadline and as Gordon Ramsay's roving reporter on the The F Word.
