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: Eternal released their hugely successful debut album, Always & Forever, in 1993. It was the first album to sell more than one million copies in the UK by a female group. Redknapp left in 1995 to pursue a solo career and Eternal continued as a trio. Things turned sour for Bryan in 1998 when she was sacked from the group by the other two members. A year later, she was struck down with lupus. The group reformed with Bryan and without Redknapp in 2013 for the ITV2 series The Big Reunion. They performed a one-off concert at the Hammersmith Apollo in March 2014. Since 2005, Bryan has starred in a number of pantomimes. In 2015, she was a contestant on ITV's celebrity sheepdog trials programme Flockstars.

Career: Sayle first came to the attention of TV viewers in 1982 on the adult incarnation of Tiswas. Fronted by Chris Tarrant, OTT (Over the Top) lasted just a season, but nevertheless provided a good grounding for Sayle whose off-the-wall comedic spot proved memorable, if not overwhelming. Later that same year, a guest role in BBC sitcom The Young Ones reinforced his angst-ridden persona with audiences. Sayle proved well-suited to TV and Alexei Sayle's Stuff, his first starring vehicle, reached screens in 1988, and was well received. He racked up further appearances in Doctor Who and Lovejoy, and has given convincing performances on the big screen as the Sultan in Indiana Jones and the Last Crusade (1989) and Achmed in Carry On Columbus (1992). He starred in the oddball sitcom Paris and resurrected his sketch show in the early 1990s. Sayle featured as impresario Charles Frobisher in the BBC's adaptation of the Sarah Waters novel Tipping the Velvet. Since then, his TV acting credits have included Keen Eddie, Agatha Christie's Marple and Holby City. His various novels have been acclaimed and he has fronted several BBC documentaries.
