depends on whether or not we are saying there is an objective reality. If there is, then the film did exist. If there is not, then the film does not exist, as it did not significantly change any observer's experience and left no record. I believe in a soul which will arrive in an afterlife, but an also sometimes alarmed at the prospect the library of my knowledge and experiences will disappear, and, if my faith is wrong, there is no other form of it except what I impart to others. I hope to do things which will be remembered for many generations, but know this too will eventually erode into oblivion. I think of my life as a good meal, which is just as good if one person eats it as it is when eaten by a great party.
