Other mistake: When Alfredo projects the movie through the window on the facade on the far side of the piazza, the picture could not be as well-focused as we see it. Besides, there would not be a picture on the theater screen (at best a very faint one), resulting in a mayhem in the audience. (00:46:50)NancyFelix
Continuity mistake: When the fire starts in the projector room Alfredo is standing in a heap of burning celluloid and his pants catch fire. Then the projector explodes knocking him unconscious. However, when Toto comes to rescue him Alfredo is lying on the floor, not burning anywhere and the fire not anywhere near him. (00:50:55)NancyFelix
Continuity mistake: When Salvatore is waiting night after night under his beloved's window he ticks off a 1954 calendar, but some time before that we saw adolescent movie aficionados masturbate over Brigitte Bardot in "Et Dieu... créa la femme", which was released in 1956.

Other mistake: In a brief scene we see Toto, as a young projectionist, in the projection room rewinding one reel of film by hand from the used [A projected] reel onto a new [B ready to be projected] reel. However, the film is being rewound from A to B in a straight line. This is incorrect. The film has to be rewound top to bottom like a figure 8, if not, it will be projected with a reversed image. Of course, it has to be rewound, if not, the film would be projected from end to beginning.
