“The Assembly’s had more response than anything else I’ve ever done,” Sheen tells me. “Almost every day someone will come up to me and mention it, particularly people who have children with autism. They say it was just so lovely to see something where the interviewers were empowered. I had a fantastic time.” He replays some of his favourite moments: the young man Leo who took an age to start talking, and then delivered the most beautifully phrased question about the influence of Dylan Thomas on Sheen’s life; the woman who asked what it was like to be married to a woman only five years older than his daughter; and the question that came at the end: “What’s your name, again?” He smiles: “And Harry with the trilby on. Just the nicest man ever.” You came across as an incredibly nice man, too, I say. “Aw well, it’s hard not to be when you’re among all those amazing people, innit.”
Today we meet in London, ostensibly to talk about A Very Royal Scandal, a gripping mini-series about Prince Andrew’s infamous Newsnight interview with Emily Maitlis – the disastrous attempt to defend his honour that sealed his fall from grace. But we don’t get to the show till it’s almost going home time. Sheen’s too busy discussing all the other stuff that matters to him, away from business.
