Quiz on ITV was hugely popular with viewers thanks to its real-life and extraordinary plot, but it was also lauded for its casting. Hollywood star Michael Sheen took on the role of Who Wants to be a Millionaire presenter Chris Tarrant in the three-part-drama, and it seems the Welsh actor put on such a convincing performance, even Chris' grandson was duped!

Chris himself recently spoke out about his thoughts on the show
Quiz on ITV saw Michael star alongside other acting heavyweights Matthew MacFayden and Sian Clifford playing Major Charles and Diana Ingram. The drama told the story of the former Who Wants to be a Millionaire contestants who were accused of cheating as part of the now infamous 'coughing scandal' after bagging the million pound jackpot back in 2001.
Speaking on Radio X recently, Chris said: "It was very well made wasn't it? It was actually very well done but it is a drama, it's not factual. So most of those conversations were made up because that's what playwrights do. I mean the bottom line is he's a rotter and a cad and a bandit and he was guilty. No question in my mind at all that he was guilty!"
