Peter walks slowly up a very wet beach, shedding his flying gear and one boot. The camera switches to a long shot showing a line of gear and Peter in completely dry sand, the surf a long way off. Also, his shadow jumps to a different direction, indicating the passage of at least 3 hours. The pile of clothes behind him also differs between the close and the long shots.
While Peter is riding up the stairway with Conductor 71, they pass by the statues (on the left side of the staircase) of Lincoln, then Plato, then Mohammed, and then Solomon. When Peter realizes he needs to go back down the stairs, the statue of Lincoln can again be seen as the next statue coming up. Then, after he stands up to leave, the statue of Mohammed is once again next to him.
The opening voice-over states that the movie opens on May 2nd 1945 an hour after a 'thousand-bomber raid' (shown as somewhere in the area of Berlin). However, the last area bombing raid of the war in Europe took place on the 15th April 1945 against Potsdam (just west of Berlin).
The prologue narrator refers to stars and regions of gas between them, then says that "the starlight makes the gas transparent, and where there are no stars, it appears as dark obscuring clouds." Transparency is actually caused not by starlight but by the absence of dust; starlight will either have no effect on the appearance of gas, or will cause it to be illuminated or perhaps to fluoresce. Dark obscuring clouds are those that contain dust and are not illuminated.
When the prologue shows the Earth and moon, the sunlight is falling on them from different directions. Also, their motion is in the wrong perspective with that of the stars as the viewpoint moves; some stars seem to be farther away than the Earth, but closer than the moon.
After Peter's second encounter with the Heavenly Messenger, this time in Frank's library, the doctor and June desperately attend to Peter's condition. June kneels in front of Peter and begins to giggle uncontrollably, then expertly hides herself behind Frank to avoid the camera.
