I once had breakfast with Dustin Hoffman and others at the Old Swan hotel in Harrogate in 1978. Our company had a convention there at the same time as the movie "Agatha" was being filmed there. It told the story of Agatha Christie's famous disappearance from her home in the 1920s owing to marital and mental problems. This was front page news at the time and she stayed at the hotel revisiting the place, scene of lovers' trysts involving her unfaithful husband and his mistress. Hoffman was quite happy to discuss his past filming experiences. Also at the bar we did have a couple of drinks in the company of Vanessa Redgrave (Agatha) and Timothy Dalton (her husband and a staunch City supporter). We did witness several movie scenes lined up. Extras were scrutinised for unsuitable clothing, watches etc for the period. Good and unexpected experience.
