Is there a list of which ones are vulnerable?

15/70mm film to be exact. IMAX 15/70mm is different to standard 5/70mm you would get in a normal cinema.

He uses the camera negative as much as possible and avoids CGI as much as possible so a lot of film hasn’t been digitised and reprinted it’s from the actual source.

Computers are designed to run 24/7 so as long as you have proper cooling your PC will be fine. It would be good to post your specs too.
