I love that film so thanks to Colinbellsjockstrap for the link. I hadn't realised much of it was shot around Bradford. Always thought it was mainly Salford.
A couple of interesting snippets. The first is that the Assistant Director was Peter Yates, who was most famous for Bullitt but whose first film as Director was Cliff Richard's Summer Holiday. The other snippet is that I interviewed an author called John Harding about 18 months ago. John wrote the superb biography of Billy Meredith, which had just been revised and re-published, but was in Salford to give a talk about Shelagh Delaney, who he'd also just finished a book (Sweetly Sing Delaney) about. Delaney had been denounced by the great and good of Salford originally as it was thought she portrayed a very negative image of Salford.
After we'd talked about the Meredith book John told me that the leading figure on Salford Council, Sir Sidney Hamburger (who was a leading figure in the Manchester Jewish Community and who I knew as did everybody who played some part in that community) had absolutely lambasted her over the "persistent denigration of Salford and its people ... which makes me want to vomit." Now of course she's recognised for the talent she was and there is an annual Shelagh Delaney Day in Salford.
