The idea of relive the same story in different ways has already been dealt with many times in different movies. 
Among the most famous: “Sliding Doors”, “Run Lola Run”, “Groundhog Day”, until the most recent “Edge of Tomorrow”.    

Mostly in the last two cited movies, the story besides changing “evolves”, and the protagonist, just like into the MULTIFILM, succeeds progressively to come closer to its final objective. In the case of “Groundhog Day”, Bill Murray succeeds, after numerous tries and errors, to fall in love together with Andie Macdowell. In the case of “Edge of Tomorrow”, Tom Cruise, after being dead and having started from the beginning again, finds the way to save the planet defeating the alien invaders.

These, however, are normal movies that if reviewed from the beginning to the end will always be the same. Moreover they will look identical to anyone who sees them.    

On the contrary the MULTIFILM will be different for each one; as every viewer will gather pieces of the mosaic in different order. 
Two people that watched the first 100 visions of a MULTIFILM, would realize, confronting each other, they hadn’t been shown the same thing; for it is a work that assembles randomly each vision, drawing from millions of possible combinations and presents itself in an almost unique way for each viewer.     

Furthermore the MULTIFILM entertains longer (hundreds, if not thousands of hours; instead of two hours for a normal movie) and offers a greater productive optimization.
