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.

Career: Despite a healthy stand-up career, O'Hanlon didn't become famous until he took the role of nice-but-dim Dougal in the acclaimed Channel 4 sitcom Father Ted. The series ended in 1998 following the sudden death of co-star Dermot Morgan. Since then, O'Hanlon has been associated with a number of projects, including roles in the sitcom My Hero and light-hearted drama Big Bad World. He also provided the voice of Robbie the Reindeer in three animated films. He's written novels that were well-received by critics, and starred in West End hit See You Next Tuesday. Other projects include Blessed, Doctor Who, The Adventures of Greyfriars Bobby, the RTE sitcom Val Falvey TD, and Dublin's Gate Theatre production of God of Carnage.
