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: Hart did a stint at the Edinburgh Festival and unsuccessfully tried to pitch a show to BBC executives in 2004. It was attended by Jennifer Saunders who loved her performance so much, she cast her in both French & Saunders and Absolutely Fabulous. Hart also had roles as various characters in sketch show Smack the Pony, and starred in BBC Three's Hyperdrive alongside Nick Frost, which was met with an indifferent response from critics. She was then cast as clumsy cleaner Barbara in Lee Mack's Not Going Out and as 'Tall Karen' in 2007's Monday Monday. After gaining further success with radio shows, she was given her own eponymous series by the BBC. It was to prove a hit with viewers who liked its retro and family-friendly style. She's also enjoyed dramatic acting success with Call the Midwife.

Career: Mangan became a regular on the West End stage, and apart from some foreign adverts, steered clear of TV work for years. He made his film debut in Martha, Meet Frank, Daniel and Laurence in 1998, and had a small role in Billy Elliot. Early TV appearances came in Big Bad World, Sword of Honour, In Defence and Human Remains before his big break as the lead in Adrian Mole: The Cappuccino Years. He's worked consistently in movies and on TV ever since, with roles in Jane Hall, Marple, Never Better, I'm Alan Partridge, Hyperdrive, and the acclaimed Green Wing. His recent work includes Dirk Gently and Episodes on TV, as well as several well-received stage performances.

Career: His stand-up career started to take off _ he won the So You Think You're Funny? competition in 2001 and two years later was nominated for the Best Newcomer Award at the Edinburgh Fringe Festival. In 2002, he also won over a younger audience when he was cast as Archie the inventor in the children's TV series Balamory, which ran for three years. Since then, he's gone on to appear in acclaimed sitcoms such as The Thick Of It and Rev, and has cropped up on numerous panel shows. He's also appeared in films ranging from Johnny English Reborn to Grimsby and The Legend of Tarzan, and took over from Sandi Toksvig as the host of Radio 4's The News Quiz.
