There were questions raised in this thread (too many pages for me to find it) asking when UK production switched from 1.75 to 1.85. I had suggested that it was sometime in the late ‘60s to early ‘70s but that it didn’t seem to happen suddenly. 1960s copies of Kine Weekly show that in 1964 almost all British films were 1.75. By 1967 there had been a change with about half of Pinewood Studio’s films being 1.85 and all Twickenham and Lee Studios being 1.85 although at the end of the ‘60s there were still a number of films at 1.75. There is hardly any mention of 1.66 throughout the ‘60s yet people continue to maintain that 1.66 was the UK standard until the change to 1.85. A couple of examples; REPULSION (1965) is 1.85 (the Criterion is 1.66) and DARLING is 1.85 (MGM DVD is 1.66). I’ll provide a more detailed report when I’ve had time to peruse Kine Weekly more closely – possibly next week (my research has to be carried out on Mondays!).
