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.

Career: Started as a stand-up comedian, presented short-lived game show Carnal Knowledge and appeared on Father Ted. Got his big break in 1997 presenting The Jack Docherty Show while the regular host was on holiday. Norton won Best Newcomer at the British Comedy Awards, beating Docherty who had been nominated for the same plaudit. In 1998, he landed his own chat show, So Graham Norton, and started the production company, So Television. He signed a multi-million-dollar contract to host an American version of his chat show, The Graham Norton Effect, before moving to the BBC in 2004, presenting programmes including Strictly Dance Fever and The Bigger Picture. Since then, his star has gone into orbit, fronting endless musical reality shows, resurrecting his chat show, and recently taking over as the voice of Eurovision.
