Not long afterwards, I got a message to say Raynor Winn had written a memoir called The Salt Path, recounting her journey along the same route at a similar time, during which her husband, Moth, occasionally enjoyed the benefits of being mistaken for me. I gave it my blessing – if that’s what was being sought – because the couple sounded down on their luck. Millions of sales, a clutch of literary prizes and several years later, I got an email from a production company, seeking a similar blessing and sending pages of a script for The Salt Path movie. Once again I was the running gag, but this time Moth is confused with the poet laureate, because it’s funnier if the person he is mistaken for holds that office. When I pointed out to the producer that I wasn’t the poet laureate when I made the trek, she said, “It’s not real.” To which I replied, “But I am.”
Sorry for long quote from the New Statesman article, but it has occurred to me that the original "message" re TSP book was from PRH or someone associated with them. Now, SA is a public figure and was before he became PL, so was that why he was contacted when people who were talked of very badly in the book (guy running campsite, cafe owner) weren't, even though a couple of them have come forward after the scandal broke as they were able to identify themselves and spoke of the effect the book had had?
I think from the film makers POV they risked inviting the public wrath of someone with a voice and clearly thought better of it. The "It's not real" "but I am" is very, very telling in the context of what we now know and I greatly respect SA for saying it.
