Film, like the railways, is one of those industries that a few years ago nobody would have predicted would get a new lease of life, and how! through technological evolution.
Up to digital, film had reached the limits of what it was capable. The movie 2001: A Space Odyssey still seems quite effective today, but the end of film effects are limited and seem like something out of the ark.
I was talking to a young person recently about how wonderful it was when self-recording was first available. We could record a TV programme or film on TV and watch it again and again at our leisure. A revolution! To pause live recordings and replay while recording something seemed like complete fantasy.
