Here's a short film produced by Eastman Kodak showing the care and handling of a film, from printing in the laboratory to distributor to film stations to projector. It's offered as a DRAGNET-style story, with a murder victim (a tattered reel of film) and witnesses, each explaining what they are supposed to do to maintain the perfection of the print -- with views of them in operation -- and their denials that they did anything wrong.
In this post-film world, where even theaters mostly use disks or even internet-connected data to produce images, it's good to take a look backwards and see how film, the medium for movies for almost a century, needed to be handled.
