In A guy named Joe (1943), Dorinda (Irene Dunn) sees Pete (Spencer Tracy) in Scotland and notices his plane. She asks the question:
Dorinda: Is that your plane?
Pete: The B-25 over there that looks like a ghost? Sure it's my plane. Why?
Dorinda: Nothing. Nothing.
In the Spielberg remake, Always (1989), it happens again (with Holly Hunter and Richard Dreyfus), but less explicitly:
Dorinda: Is that your plane?
Pete: Yeah, that's my plane. C'mon, a shortcut.
Nothing more (that I can tell) is mentioned in either movie about this weird exchange, but Spielberg felt it necessary to translate this seemingly unimportant, trivial exchange to the remake.
Am I missing something? I get the allusion to a "ghost" (though only in the 1943 version), and see that the plane is spooky-looking, but is that all there is to it? Unexplained, tangential foreshadowing?
