Career: Carr began performing on the stand-up circuit, doing up to 300 shows a year for three years, before taking his act to the Edinburgh festival in 2002. This brought him to the attention of TV bosses, and before long he was presenting series such as Your Face or Mine and Distraction. Since then, he's rarely been off TVscreens, hosting the first run of the Friday Night Project, 8 Out of 10 Cats and numerous Channel 4 list shows.

Away from the numbers and letters on Countdown, she began co-hosting The Gadget Show alongside Jason Bradbury in June 2013. She was a contestant on Strictly Come Dancing in 2013 and was the fifth celebrity to be eliminated.

He made his big-screen directorial debut with the acclaimed Submarine (which he also wrote, adapting it from the novel by Joe Dunthorne), and has since directed The Double as well as numerous music videos for acts such as the Arctic Monkeys, Super Furry Animals, the Yeah Yeah Yeahs and Kasabian.

Career: In 2003, Richardson won his heat of the BBC New Talent Comedy Search, and a year later did well in the Laughing Horse New Act of the Year competition and J20 Last Laugh Comedy Search. Encouraged by these successes and kind words from Jasper Carrott and Dave Spikey for a performance at the Criterion Theatre in London, his confidence grew. More stand-up followed, including appearances at the Edinburgh Fringe Festival. He went on to feature on numerous radio shows before moving into TV. Richardson appeared on Never Mind the Buzzcocks and Have I Got News For You before becoming a team captain on 8 Out of 10 Cats.
