She might have the same producer as Graham Norton, but will Claudia Winkleman’s new series succeed? Seasoned pros from Esther Rantzen to Kirsty Wark for the tips and tricks of creating interview gold

Claudia Winkleman’s new chatshow will land next month, and its enthusiast army are already excited. Winkleman herself, who doesn’t come off at all breathy, said: “I can’t quite believe it and I’m incredibly grateful to the BBC for this amazing opportunity.” Kalpna Patel-Knight, who commissioned The Claudia Winkleman Show, observed: “Claudia is a true national treasure – warm, witty and endlessly entertaining.” Graham Stuart, long-term producer/buddy of Graham Norton, who runs So Television, which produces both, said of his new venture: “How can you possibly follow [Graham Norton]? By booking a host equally as brilliant. So we have.”

And if anything proves how hard it is to create great chat, it’s those quotes. If anyone was ever that bland and blow-hard on one of their chatshow sofas, most TV people would punch themselves in the head. No wonder so many chatshows struggle when they first come out – it’s not that the expectation is too high, exactly, so much as the fanfare is too boasty. Brilliant as she is, then, the success of Claudia’s new series is far from given. But how exactly do you go about creating chatshow magic?
