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: Alongside her stand-up work, Bea has carved out a successful career as an actress. She made her acting debut in the comedy series The Savage Eye. She has had recurring roles in Cardinal Burns, Dead Boss, Trivia, The Town, The Delivery Man and Trollied. More recently, she starred in The Fall.

Career: Brown has had a long TV career, and in the 1970s took roles in Coronation Street, Doctor Who, Angels and Survivors. She has been actively involved in the theatre and is recognised as a great Shakespearean actress - but only became a household name when she joined the cast of EastEnders in 1985. She took a break from the soap in 1993, but Dot Cotton returned four years later and has stayed there ever since. Away from the Square, Brown has appeared in the movie Bean, and played Nannie Slagg in the BBC's big-budget production of Gormenghast in 2000.

Career: Chiles rose to become an assistant producer and was soon presenting BBC Two business show Working Lunch, where he became a popular face. He also launched his own show, Chiles on Saturday, on BBC Radio Five Live, which was awarded the sports category Gold Medal at the Sony Radio Academy Awards in 2002. For BBC One, he fronted Royal Millions, an investigation into the Queen's finances, and was the original presenter of The Apprentice: You're Fired. He became a housewives' favourite while co-hosting The One Show with Christine Bleakley. They eventually moved to ITV and had a short-lived spell fronting Daybreak. Chiles has also hosted football coverage on both the BBC and ITV. He is famous for his love of West Bromwich Albion.

Career: Walsh supported Stephen K Amos between 2008 and 2010 and performed his 2012 show Seann to Be Wild at the Edinburgh Festival Fringe before taking it on tour. He has also performed shows with Josh Widdicombe. Walsh is a regular guest on TV comedy panel shows, including 8 Out of 10 Cats, Mock the Week and Virtually Famous.
