the truth was adapted for the purposes of the plot. For example, in there is an account of Sinclair letting a car run away and demolishing the local golf club hut. He read this and the next time he met Wight he said "'I don't remember doing that', and he said, 'You didn't it was me.' You see, it didn't fit James Herriot's image in the book, so he put it on to Tristan." In 2017, Alf Wight's son, Jim Wight, was interviewed and he discussed the James Herriot franchise. He made these comments about Sinclair: The 1975 film All Creatures Great and Small was the first adaptation of Wight's semiautobiographical novels of James Herriot. It was directed by Claude Whatham, and starred Simon Ward and Anthony Hopkins as James Herriot and Siegfried Farnon, with Brian Stirner taking the part of Tristan. At the time of filming, Stirner had played the lead role in Overlord, Stuart Cooper's 1975 film about the D-Day landings. From the first film onwards, Wight gave a percentage of his income from film and television rights to Sinclair and his brother. The sequel, It Shouldn't Happen to a Vet, premiered in 1976, but did not feature a Tristan character. Encouraged by the cinematic success of the films, the BBC commissioned a television adaption of All Creatures Great and Small. Christopher Timothy starred as Herriot, Robert Hardy as Siegfried, and Peter Davison as Tristan. After the first rehearsal, Davison met Sinclair, and stated that meeting him "was useful because I'd worried about how to make my Tristan endearing even though he behaved appallingly." In return, Sinclair has said that he was "flattered that someone as tall and handsome as Peter Davison would play him on screen." The series premiered in 1978, and ended in 1980, when Herriot and Tristan were shown to leave Darrowby to join the war effort. A new series was commissioned in 1988, but Davison had other acting commitments, and was only able to make a few appearances as Tristan in that series. All Creatures Great and Small has been adapted for the stage by Simon Stallworthy. The play was first staged in 2010 at the Gala Theatre, Durham, with Jack Wharrier playing Tristan. In 2014, a provincial tour of the play was produced by Bill Kenwright, with Tristan being played by Lee Latchford-Evans. Since 2020, a new television adaptation of All Creatures Great
