In 2023, Hitchon sent producer Claire Lewis an ‘almost coded email’ telling her that he intended to be here for the 70 Up series, but Lewis said ‘reading between the lines of his emails, I realised how extraordinarily ill he was’.While the final series hadn’t yet been commissioned, Lewis persuaded ITV to fly her and a camera crew out to visit 65-year-old Hitchon in 2023, where he recorded a final interview.

I have a cancer in my throat and I don’t know what the prognosis… I don’t know what’s going to happen,’ he told the show.’So I’m not really focused on the long-term future. I’m focused on fairly short-term futures at the moment. I’m just keeping going and not asking too many questions about the long term.’ The programme was actually meant to conclude with 63 Up in 2019, following the death of director Michael Apted, but it was participant Nick Hitchon’s devastating cancer diagnosis which prompted the filmmakers to return (pictured in 63 Up in 2019) The son of a Yorkshire farmer, Hitchon went on to study at the University of Oxford before moving to the US in the early 80s where he worked as a nuclear fusion expert (pictured in 21 Up in 1977)’This section with Nick is hard, and I think we all know that he’s no longer with us. God bless him. I am currently in remission, and Nick is right. Focus shifts to the short term. What can we – all of us – do with the time we have left? Not waste it, would be a start,’ wrote one emotional viewer on X.’Kleenex at the ready for the final 10 mins? Nick,’ added another, whilst one wrote: ‘I’m bawling already knowing Nick is no longer with us.’ ‘All of it is making me very emotional. In the blink of an eye, hopes and aspirations are just distant memories and time has run out. Life is over so very quickly. Too quickly,’ agreed one more. In the final episode viewers will see Hitchon’s last interview in which he reveals that he had a stroke in 2022. ‘It’s a surprise to my doctors that I’m still around. Curious really,’ he tells the cameras. ‘One was saying: “It does happen that people survive” but made it clear he didn’t expect it. They should train them to be more tactful.’Admitting that he was so weak he could barely walk more than a few steps, he says that his illness has been hard on his family, including his second wife, Cryss Brunner. ‘Everybody has had to pick up the slack and I feel awful about it,’ he says. ‘This section with Nick is hard, and I think we all know that he’s no longer with us.

Most of all, I hope filming that last interview did the same for Nick.’The final episode of 70 Up featuring Hitchon’s final appearance will air on September 22 on ITV.
