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: 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 originally intending to pursue a career as a serious actress, her comic abilities saw her quickly noticed by talent scouts. She landed a role in ITV's Doc Marten before The IT Crowd came along. Other recent roles include hit movie The Boat That Rocked and sitcom The Old Guys. She also has several theatre credits.

Career: After a spell working in Italy, Spence returned to London to pursue a career as a commercial dancer. During the 1990s, he toured and worked with Take That, E17, Boyzone and Bjork and was one of only five male dancers selected to accompany the Spice Girls on their debut world tour. Further work in London followed when he joined the West End cast of Cats and the Pet Shop Boys's musical Closer to Heaven. After becoming disheartened by the West End's eight show weeks, he started Edit Agency at Pineapple Dance Studios, where he is currently Artistic Director. TV beckoned when Trouble TV cast him as their Boot Camp mentor for three series of Bump N Grind. Other TV work followed and his big break came on Sky1's fly-on-the-wall documentary series Pineapple Dance Studios. More recently, he was a judge on the seventh series of Dancing on Ice, alongside Robin Cousins and Katarina Witt. In August 2013, he entered the Celebrity Big Brother house. In early 2015, he was a contestant on Channel 4 reality series The Jump.
