Career: Davies performed his first stand-up gig in 1988, and by the early 1990s was a rising star, picking up rave reviews at Edinburgh. He later gave up playing clubs to concentrate on radio. His Radio 1 series, Alan's Big One FM, led to TV appearances on shows such as One Foot in the Grave, before he was cast as the lead in Jonathan Creek, the light-hearted mystery drama that made him a household name. Other acting work includes Bob and Rose, A Many Splintered Thing, The Brief, Marple, Angus, Thongs and Perfect Snogging (2008), Lewis and Whites. He presented the three-part documentary Alan Davies' Teenage Revolution for Channel 4 in 2010 and was a judge in 2011 on ITV talent show Show Me the Funny. He's also appeared in West End hit Auntie and Me. He has been a permanent panellist on irreverent quiz QI since the show began in 2003.

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: Osman has worked behind the scenes as an executive producer on a number of TV programmes, including Deal or No Deal, 8 Out of 10 Cats, and 10 O'Clock Live. As the UK creative director of TV production company Endemol, he pitched the quiz Pointless to the BBC. As a way of explaining the rules, he played the co-host during a run-through. He was asked to do the role for real when the show was commissioned. Pointless started on BBC Two in 2009 and was an immediate hit. It quickly made the switch to BBC One. Since being in the spotlight on Pointless, he has made guest appearances on QI, Have I Got News for You and Would I Lie to You? He also guest presented an episode of The One Show alongside Alex Jones.
