It was Mario Maisto who discovered the unknown objects in the movie, "Milano-Palermo: il ritorno".
After a thorough analysis of the footage, Mario Maisto determined that the UFOs were self-luminous and spherical in shape. Furthermore, he established that due to their manoeuvres, the UFOs cannot be birds, balloons, satellites or known aircraft.
In the Altro Giornale.org and Ufodigest.com articles he presents several stills from the first video. These stills show a second and third UFO sphere (that cannot be seen in the video) to the right of the actor.
One can clearly see that the UFO in the first video stops on a dime.
Mario Maisto presents several videos which show the UFOs:
First scene (11 seconds into the video, to the left of the actor's head):
