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: Morrissey's big break came at the age of 18 when he landed the lead role of Billy Rizley in Channel 4's first drama series, One Summer. After that he trained at Rada. A steady stream of small-screen and theatre roles followed. At the 2004 Bafta awards, Morrissey was nominated for Best TV Actor for his performance in the drama serial, State of Play. In the same year, The Deal, in which he co-starred as Gordon Brown to Michael Sheen's Tony Blair, won the award for Best Single Drama. Projects since include Blackpool, Cape Wrath, Red Riding, Basic Instinct 2, Nowhere Boy, Mrs Mandela, Doctor Who and a starring role in adaptations of Mark Billingham's Tom Thorne books for Sky1. In 2012, he joined the cast of The Walking Dead, and continues to work on stage whenever his busy schedule allows.

Career: Willoughby's big break came in 2004 when she returned to CITV as co-presenter of Ministry of Mayhem. The show was later renamed Holly & Stephen's Saturday Showdown. She has worked on TV series Feel the Fear, Stars in Their Eyes and CD: UK. She earned a prime-time slot as co-presenter of Dancing on Ice in 2006, the same year she won a Bafta for her work on children's TV. Other small screen duties have included Greased Lightnin', The Xtra Factor, Streetmate, Holly & Fearne Go Dating, Here Come the Boys and Celebrity Juice. She has co-presented This Morning with Phillip Schofield since September 2009 and co-presented two series of The Voice UK alongside Reggie Yates. In 2012, she began hosting a revived version of Surprise Surprise, and is also the presenter of sports quiz Play to the Whistle.
