Yeah, I haven't been involved in film projection since late 1998. Back then, it was at my university student cinema, we had 70mm capability but only showed one or two films a year in 70mm because there were so few films available for us to hire in that format. If I recall, the main one we showed every year was Backdraft. By comparison, there were 2 showings per day during term time (so 7x10x3 days per year) and most films would only be shown 1 or maybe 2 nights. I was told then that we were very lucky to have that projector as there were only around 4 or 5 cinemas in the country with 70mm projectors (other than IMAX), and I can only imagine it's gone down since then. That said, it's hard to find information on it now - the only list of 70mm cinemas I could find had 5, but included IMAX and not my university cinema even though they showed Interstellar in 70mm last year so probably are just not listed because it's not open to the general public.
